NEWS: STATISTICS, LAWS AND ALL OTHER LASER POINTER NEWS
This webpage has a chronological list of general laser pointer news. There are separate pages for specific aviation-related incidents and non-aviation-related incidents. In addition, the What’s new at the website page lists major changes, updates, and additions to LaserPointerSafety.com.
We sometimes add older news items; since the list is chronological, items new to this page won’t always appear at the top. You may want to scroll down to see if there are new items since the last time you visited.
If this pace continues, there would be over 11,977 laser incidents reported for 2016 (e.g., if 2016’s total incidents were to rise 55% higher than 2015’s incidents).
In a social media post around late March 2016, Kaye posted photos of a dinosaur’s eye that is only visible with his technique.
A science story notes that Kaye is “maybe the only person on Earth not named Sam Neill who can say he’s looked into the eyes of a pterosaur.”
In previous studies he used green (532 nm), blue (457 nm) and violet (407 nm) laser modules with powers from 150 to 500 milliwatts. This provides much brighter illumination of the subject. For example, a standard 20 watt ultraviolet fluorescent lamp has an irradiance (power over a given area) of 510 milliwatts per square centimeter. A 500 milliwatt (1/2 watt) laser, by comparison, provides an irradiance of around 4000 to 8000 milliwatts per square centimeter.

The story “What Did Dinosaurs Look Like? Tom Kaye Finds Answers, Feathers With Lasers” appeared online at Inverse.com on April 19 2016. Inverse also featured a previous story, “Lasers Can Tell Us More About Fossils Than Before” on October 8 2015. A May 27 2015 paper by Kaye and associates, written for the online journal PLOS ONE, “Laser-Stimulated Fluorescence in Paleontology”, is here.
But in addition to this declaration, the authors also provided a succinct summary of the current state of consumer laser pointer misuse, and how ophthalmologists should proceed when studying a patient’s laser exposure.
Experts John Marshall, John O’Hagan and John Tyrer began by noting that low-powered Class 1 (less than 1 milliwatt) and Class 2 (1-5 mW) lasers “are not an eye hazard, and even if used inappropriately will not cause permanent eye damage.”
However, consumer laser devices with Class 3B (5-500 mW) and Class 4 (above 500 mW) powers have begun to cause injuries. “….[C]lass 4 devices are capable of causing irreversible retinal damage if directed into the eye over short ranges, up to several metres. Such devices have resulted in foveal injuries in children with current estimates of 150 cases in the UK. The [UK] media has given significant coverage to this growing problem.”
Ophthalmologists were advised that in cases of close up exposure, there may potentially be permanent damage. A detailed examination would be warranted, although there is no treatment to reverse permanent damage.
The hazards from this short range misuse differ from the hazards of aiming a laser towards pilots. Because the laser-to-aircraft distance is typically “hundreds to thousands of metres”, and because of scattering from the windscreen, eye injuries are nonexistent: “Fortunately, these exposures are at irradiances that are incapable of producing irreversible retinal damage even at distances of 100 m.”
They said that only one case of alleged retinal damage has been reported in pilots. [LPS.com note: this is for publicly available reports involving civilian pilots.] The experts concluded the case is suspect for a number of reasons; they do not believe laser targeting caused the alleged injury.
Marshall, O’Hagan and Tyrer turned from injuries to the hazards of distracting pilots with bright laser lights: “Obviously, if such a distraction occurs at a critical time such as during landing then the result could be devastating.”
For ophthalmologists examining pilots, if there are no permanent abnormalities on an Amsler grid test, the physician should not do any detailed eye exam, as this “would only serve to compromise the pilot's vision for a longer period.” The authors noted that pilots may delay seeing an expert for “many hours or a day or so during which there may be a growing psychological element.”
In an interview with CNN, Marshall said the findings on pilot hazards are based on previous laser safety research as well as a new study done with field experiments at a military base over about three years.
In the BJO editorial, the three experts agreed that current laser safety standards and guidelines are based on valid experiments and science. The standards do not need to be revised, “…but clearly further attempts must be made to educate the public.”
The editorial concluded “The European Commission has mandated the European Standardisation bodies to produce a standard specifically for consumer laser products. This should allow enforcing authorities to remove unsafe products from the market. However, compliance by manufacturers will remain an issue, as will direct imports by the public purchasing unsafe laser products over the internet.”

Dr. John O’Hagan said that many of the handheld laser pens and pointers being sold on eBay “are very clearly not one milliwatt.” According to eBay guidelines, such lasers above 1 mW are not supposed to be listed. O’Hagan noted that the pens may be “misleadingly …. designed to look like less powerful lasers, and are priced at only around £5 [USD $7], so people may not even be aware of what they are buying.”

Loudon estimates that eBay sales “are in the thousands” each day. According to the statement, “Currently there are over 2000 laser pens for sale on eBay UK. It appears 90% of the listings are for products that are clearly over 1mW and often with sales histories of thousands in a single listing. Multiply that and it becomes really obvious where all these overpowered lasers are coming from that idiots are abusing.”
He calls for eBay to begin “monitoring and delisting all these crazy hyped up laser listings”.

The head of the Air Canada Pilots Association said that the figures show that education is not working, and handheld lasers should be designated as prohibited weapons.
From CBC News. Note that a few days later, the Ottawa Citizen did an analysis of Transport Canada’s database which shows different figures: 663 laser incidents in 2015, which is up 32% from the 2014 total of 502.
The following is from the BALPA website, Feb. 15 2016. More news items referencing BALPA are here.
LASER INCIDENT SHOWS MORE ACTION IS NEEDED
Last night’s laser attack incident clearly shows why more needs to be done to tackle the growing use of lasers against aircraft.
The crew of Virgin Atlantic flight VS25 bound for New York took the decision to return to Heathrow after reportedly being attacked with a laser shortly after take off.
Jim McAuslan, General Secretary of BALPA, said,
“This is not an isolated incident. Aircraft are attacked with lasers at an alarming rate and with lasers with ever-increasing strength.
“It is an incredibly dangerous thing to do. Shining a laser at an aircraft puts that aircraft, its crew and all the passengers on board at completely unnecessary risk.
“Modern lasers have the power to blind, and certainly to act as a huge distraction and to dazzle the pilots during critical phases of flight.
“We are sure the police will do everything in their power to find the culprits of this attack and prosecute them.
“We repeat our call to the Government to classify lasers as offensive weapons which would give the police more power to arrest people for possessing them if they had no good reason to have them. This incident shows why this is becoming more-and-more urgent.
“Pilots across the world know how dangerous laser attacks are and therefore will join with me in commending the actions of the crew of VS25 who put their passengers’ safety first and took the decision to return to Heathrow.”
For comparison, in the United States from January 1 2009 through May 31 2015, there were 21,414 laser incidents reported to the Federal Aviation Administration. (An additional 457 incidents were reported during June 2015.) From January 1 2004 through December 31 2015 there were 29,097 laser incidents reported to FAA.

As of February 4, Califf’s nomination still awaited Senate approval.
Sen. Schumer, a Democrat from New York State, issued a statement saying “We’re only one month into 2016 and already there has been a green laser strike targeting aircrafts in the New York metropolitan area. We need to do something, and that is why I am pushing the FDA Commissioner nominee to act ahead of his confirmation. Green laser pointers have been a repeated danger to pilots across the country and I will continue to urge the FDA to use its authority and finally ban green, long-range, high-powered laser pointers once and for all.”
According to Newsday, there would be an exemption for professional uses. No additional details on the exemption criteria were available.

Examinations were done within three days of the strikes: “Early Treatment Diabetic Retinopathy Study visual acuity, colour vision, visual fields, intraocular pressure, slit-lamp examination, dilated fundus examination, colour fundus photographs, and ocular coherence tomography.”
The paper concluded, “Our study revealed that laser strikes on aircraft did not result in permanent visual functional or structural deficits. However, laser strikes cause immediate visual effects, including glare, flash blindness, and ocular irritation that can interfere with a pilot’s visual function.”
From the Canadian Journal of Ophthalmology, December 2015, Volume 50, Issue 6, pages 429-432. For the full abstract of the study, click the “Read More…” link.
Here is the same data, presented to show the number of incidents per day:
Below is a closeup of the 2014-2015 data. The thin light blue line represents the number of incidents on each day. Note the wide variability, from as few as no reports in a day (May 27 2014) to as many as 65 on December 11 2015.The thick blue line is a 30-day moving average, to smooth out the data.
Both charts show identical data. On the second chart, two dates have been highlighted. Around July 1 2015, the number of incidents per day (light blue line) starts to increase. The only significant change that LaserPointerSafety.com can find around that time, is that on July 16 (purple line) there was widespread nationwide publicity about 11 flights that were illuminated on July 15 in and around New Jersey.
However, this event is not a full explanation. While the publicity may have triggered a “copycat” effect, it is apparent from both the thin and thick lines that incidents had been increasing at least two weeks prior to July 16.
Another date with widespread nationwide publicity is marked, November 12 2015 (red line). Three news helicopters and a police helicopter were illuminated in New York City the night before. Again, while there is some increase in incidents after that date, there also was a consistent increase from July through November.
Based on this analysis, “Copycat” laser use does not seem to be a significant factor in the near-doubling of 2015 laser incidents.
“An airline pilot presented to our department complaining of a blind spot in the upper left area of his visual field in the right eye (right supero-nasal scotoma) following exposure to a laser beam while performing a landing maneuver of a commercial aircraft. At around 1300 ft (396 m), a blue laser beam from the ground directly entered his right eye, with immediate flash blindness and pain. Spectral domain ocular coherence tomography highlighted a localized area of photoreceptor disruption corresponding to a well demarcated area of hypofluorescence on fundus autofluorescence, representing a focal outer retinal laser injury. Fundus examination a fortnight later revealed a clinically identifiable lesion in the pilot’s right eye commensurate with a retinal-laser burn.”
The paper said the pilot’s symptoms “fully resolved 2 wk later” and that there was no “deficit in visual function.”

The April 30 2015 decision by three judges of the Ninth Circuit found that prosecutors had not presented evidence of “reckless endangerment” of aircraft. The judges sent the case back to the U.S. district court in Los Angeles for a new sentencing hearing under a new judge. Under the original sentencing guidelines, Gardenhire had been recommended for 27 to 33 months in prison taking into account the reckless endangerment charge, or 4 to 10 months in prison without the charge.

An AirSafe summary noted that from 2010 through 2014, there were only eight days with no laser encounters reported in the U.S. The graph below shows the distribution of incidents, with most days having between 7-12 laser strikes:
Analysis by day of the week, and by month of the year, showed Friday and Saturday evenings as having a greater likelihood of illuminations. July through November saw higher-than-normal numbers of incidents.
The AirSafe study also looked at six selected metropolitan areas. It compared the number of flights to the number of incidents. Phoenix, Los Angeles and San Francisco had higher-than-normal numbers of incidents; Chicago and New York were about average, and Atlanta was below average.

Between November 18 and December 6 2015, there have been at least three incidents, involving six aircraft, where pilots were illuminated with light from “Star Shower” laser projectors. In all cases, the illumination appeared to be inadvertent. The devices were being used for holiday decorating, and stray beams went into airspace. (E.g., a person was not knowingly aiming the Star Shower at an aircraft, or the flight path of an aircraft.)
The Star Shower emits “thousands” of laser beams from two sources, one green and one red. A homeowner can simply aim the Star Shower at her house or foliage, and instantly cover it with green, or green plus red, laser dots.

According to a comprehensive story in Inquisitr, Star Shower is so popular that it is sold out in many locations. TravelPulse calls it a “laser cannon.”
The Federal Aviation Administration on December 8 2015 tweeted “Decorating for the holidays? A stray laser could blind a pilot.” They then provided a link to general information about laser/aviation safety. An FAA spokesperson told CBS Philly, ““I don’t think anybody who buys these devices even think they have enough power to hit an aircraft in the sky…. If the box is aimed a little high, some of the lasers will not hit the roof of the house, they’ll keep going into space.”
While there is no warning on the outer packaging, the Star Shower instruction sheet says: “NOTICE: Lasers should not be projected at or within the flight path of an aircraft within 10 nautical miles [11.5 miles] of an airport. If your intended surface is within 10 nautical miles of an airport, lower the angle of the Star Shower so that no lasers point into the sky.”
In a December 9 2015 statement to NBC Los Angeles, the manufacturer added: “Star Shower Laser Lights operate by taking a single laser beam and diffracting it into thousands of individual laser beams. Each beam emitted by Star Shower is much lower in power than a typical laser pointer. Each individual laser beam is 10 times less than the maximum permissible exposure (MPE) allowed by the FAA normal flight zone (NFZ) criteria.”
In an urban or suburban environment, it is likely that most homes are within 10 NM of some type of airport. It may not be a major metropolitan airport; it could be a small general aviation facility. In a December 3 2015 incident, a Boeing 737 at 13,000 feet and 22 miles east of Dallas-Fort Worth Airport, reported seeing lights from what was believed to be a “laser holiday light display.”

ADVICE FOR OUTDOOR USE
After purchasing and testing a Star Shower, here is our summary advice for consumers. Details then follow.
The Star Shower is essentially eye-safe, and does not cause direct interference (glare) with pilots’ vision after about 411 feet. However, a single beamlet can be a distraction to pilots at least 3/4 of a mile away, and possibly further away due to the large number of laser dots aimed into the sky causing a flashing effect.
For this reason, a Star Shower needs to be aimed so that beams don’t go into airspace. You do not want an officer knocking on your door because a pilot saw and reported your home laser projector. While it is unlikely you would be arrested for an unknowing aircraft illumination, federal penalties for laser pointer misuse range up to five years in prison and up to a $250,000 fine.
Putting the projector closer to a house will keep more of the beams on the structure. Similarly, don’t aim it up into a tree unless the tree is very dense, such as an evergreen.
It should also be noted that there are reports such as this and this of Star Showers being stolen from yards. If you put your projector on a roof or up in a tree, aiming downwards, this both helps aviation (no beams going up into the air) and makes it harder to steal the projector. Finally, if you are in a heavy air traffic area, you might want to consider restricting it to indoor use only.
IS A STAR SHOWER LEGAL?
Under U.S. federal law, the Star Shower is legal to own and operate. As a Class IIIa (3R) laser, there are no federal restrictions on its use. The federal law prohibiting laser pointer misuse may not apply, for two reasons. 1) It prohibits knowingly aiming at an aircraft or its flight path, and 2) the law applies to “laser pointers…designed to be used by the operator as a pointer or highlighter….” This definition would not seem to apply to a device that is not a pointer, and is not used “…to indicate, mark, or identify a specific position, place, item, or object.”
A few states or localities may have restrictions on lasers that would affect Star Shower. Since it is not a laser pointer, and is not used for pointing, restrictions that cover laser pointers may not apply (depending on the exact definition). Some selected state and local laws are here.
Common sense says that a person should not stare into the beams, and that they should not be aimed to harass others. Similarly, the beams should not be aimed down a road or up into the sky, where they could interfere with drivers or pilots.
PURCHASING AND PACKAGING
In early December 2015, we purchased a Star Shower for $40 from a CVS drugstore. The box lists a sales website at BulbHead.com, and the distributor as Telebrands. It also says “Made in China.”
Both the box and the device have the proper FDA-mandated laser safety labeling. The device is FDA Class IIIa, meaning less than 5 milliwatts output. There are two apertures, one for 532 nm green laser beams and one for 650 nm red beams. A diffraction grating in front of each laser breaks the single beam into dozens or “thousands” of less-powerful beamlets. In a foggy or smoky environment, it is possible to see the beamlets in the air, but they are too weak to be seen in clear air.
Although the Star Shower has been popular for the Christmas 2015 season, the packaging does not emphasize this. Instead it says the Star Shower is “great for” indoor, landscaping, holiday, winter and summer uses. The advantages are: “No ladders, no hanging, no dead bulbs, no mess — just plug it in.”
We took it to laser expert Greg Makhov of Lighting Systems Design Inc. for testing. Keep in mind that he tested just this one sample unit; we assume it is representative of the other Star Showers that have been sold.
Makhov used two different types of power meters, both which could measure in the microwatt and milliwatt region. He found that the maximum power of a single beam was 0.4 milliwatts. The chart below shows details.
ESSENTIALLY NO EYE INJURY HAZARD
The brightest single beam, at 0.4 mW, is below the 1.0 mW Class II limit. Class II laser pointers are generally considered to be safe for accidental exposure. Eye injury from a Star Shower would be almost impossible unless a person at close range deliberately overcame his aversion to bright light and stared for many seconds into one of the beamlets, keeping it at the same spot in his visual field.
While the chart shows the Nominal Ocular Hazard Distance to be as far as 19 feet, keep in mind this is a “nominal” hazard. This does NOT mean that beams will cause injury at this distance. There is a kind of safety factor built in to the NOHD. A quick approximation is that at about 1/3 the NOHD (about 6 feet in this case), there is a 50-50 chance of a laser kept steady on the eye causing the smallest medically detectable lesion on the retina, under laboratory conditions.
GLARE UP TO 411 FEET, DISTRACTION TO 3/4 MILE
The chart also shows the visual interference hazard distances. For example, a pilot could experience veiling glare (she can’t see past the light) up to 411 feet away from the Star Shower projector. The light does not interfere with vision, but is a mental distraction, up to 4,105 feet away — a little over three quarters of a mile.
The above eye and visual interference calculations are for a single beamlet, for two reasons. First, at aviation distances, only one beamlet would enter the eye at a time. They are not so close together that two separate beamlets of the same color would be within one pupil diameter. The second reason is that even a person is so close to the Star Shower that two separate beamlets enter his pupil, each one will be focused onto a different area of the retina. This means that the beams don’t overlap — they are heating different areas. This is why we are primarily concerned — both for eye safety and for aviation interference — with the hazard of a single beamlet.
Now, when a helicopter flies through the dozens or “thousands” of laser beams, this can be more distracting than a single beam. It is no wonder that a pilot might report the laser display, and have it re-aimed or shut down.
Although an FAA spokesperson said a Star Shower was reported by a pilot who was at 15,000 feet, at this distance any single beamlet would be far below the FAA’s distraction limit. This means any beamlet would be no brighter than surrounding city or airport lights. It could be that the large number of beamlets caused flashes as the aircraft flew through them, and that this flashing was itself a distraction. Either way, no competent pilot at 15,000 feet should have any visual interference from a Star Shower. The only problem could be mental distraction, if the pilot paid more attention to the light than to flying the aircraft.

The following is a press release issued by the Senator, followed by (after the “Read More:” link) a copy of the Senator’s letter to the FDA Commissioner:
Standing in the terminal at Buffalo Niagara International Airport in Cheektowaga, NY, U.S. Senator Charles E. Schumer today called on the Food and Drug Administration (FDA) to ban the sale of high-powered, long-range green laser pointers to the public. Schumer’s push comes on the heels of multiple incidents in which green lasers were pointed at aircraft and temporarily blinded and disoriented pilots mid-flight. This includes the recent incident two weeks ago when the pilot of a FedEx plane flying over Jamestown reported a green beam of light coming from a laser on the ground lighting up the aircraft. Schumer said that while it is lucky no one was harmed in the Jamestown incident or any other green laser attack, the federal government should act before a horrific event occurs, not after.
“Simply put: these green, long-range, high-powered laser pointers are a danger to our pilots and the hundreds of passengers whose lives depend on their eyesight and training. While we are very lucky the recent incident in Jamestown did not yield devastating results, we cannot sit idly by and wait for a horrific incident to occur before we act,” said Schumer. “That is why I am calling on the FDA to use its authority to regulate these dangerous devices. They're quickly becoming the weapon of choice for wrong-doers who want to harass our pilots and put passengers’ lives in jeopardy, and they should be banned before people are seriously hurt.”
Schumer said there has been a recent onslaught of green laser pointer attacks on aircraft that threaten the safety of pilots, passengers, and civilians on the ground. According to a USA Today report, the Federal Aviation Administration (FAA) recorded more than 5,300 laser strikes from January of this year through October 16, up from the more than 2,800 laser strikes reported in 2010. Schumer said numbers like these suggest a widespread misuse of the product and mean it should only be available to qualified professionals. According to the same USA Today report, between the night of November 11 and the morning of November 12, federal authorities reported 20 laser strikes on aircraft across the country, including the case in Jamestown. Schumer said the fact that the plane was flying more than 23,000 feet in the air shows how powerful these lasers are, and how dangerous they can be when they get into the wrong hands. As a result, Schumer is urging the FDA to ban the sale of high-powered, long-range green laser pointers to the public.
Laser pointers at one time were primarily used for presentation purposes in boardrooms and classrooms, they are now wildly available at trinket shops, flea markets, retailers and on the Internet, and are much more powerful. According to the FDA, laser pointers can be momentarily hazardous when staring directly at the beam. For pilots, these green lasers can cause flash blindness, a temporary or permanent loss of vision when the light-sensitive parts of the eye are exposed to an intensity of light they are not physically meant to handle. In addition, research suggests green lasers are more dangerous to the eye than red lasers because the light spectrum is more easily absorbed by the retina and more susceptible to damage. In fact, green lasers are considered to be more than double the strength of other colored lasers and can travel for miles, according to many media reports and health and aviation experts. Schumer there are certain types of lasers for which manufacturers must obtain FDA permission before they can be sold in the U.S., and green lasers should be included in that category so they are only sold to professionals, rather than would-be pranksters.
Because the FDA has the authority to regulate these lasers and their manufacturers, Schumer is strongly urging the federal agency to make high-powered, green laser pointers unavailable for public sale; they should be restricted to those with a specific professional purpose. Schumer said that while perpetrators convicted of pointing a laser at a plane can be sentenced to 20 years in prison and a $250,000 fine, they are often hard to track down following an incident. Because the products are merely required to have a warning label, Schumer said more must be done to limit public availability in order to protect public health and safety.
Schumer was joined by Adam Perry, Aviation Committee Chairman at the NFTA, Kimberly A. Minkel, NFTA Executive Director, and George Gast, NFTA Police Chief.
“I applaud Senator Schumer for his efforts to ensure the safety of our aviation industry,” said Kimberley A. Minkel, Executive Director of the Niagara Frontier Transportation Authority. “I hope the FDA responds to the senator’s request in a manner that will make it much more difficult for laser pointers to be available. Lasing is a serious crime that poses an imminent threat to aviation safety and could result in a pilot losing control of their aircraft, thus potentially causing mass casualties.”
Previously, the FDA has noted concern about the increased availability of some laser products. According to a March 2013 study by the National Institute of Standards and Technology (NIST), green lasers generate green light from infrared light, from which the eye cannot protect itself. In that NIST report, the agency noted that ideally, the device should be designed and manufactured to confine the infrared light within the laser housing. However, according to the NIST results, more than 75 percent of the devices tested emitted infrared light in excess of the Code of Federal Regulations (CFR) limit.
Schumer said in New York incidents of green lasers pointed at aircraft have been numerous and significant. In addition to the most recent one in Jamestown, there were 39 laser incidents between January 1, 2015 and May 15, 2015 in New York City alone. In 2014, there were 17 green laser incidents out of a total 19 laser incidents at JFK airport; 37 green laser incidents out of a total 41 laser incidents at LaGuardia Airport; 20 green laser incidents out of a total 28 at Newark.
There are four major hazard classes (I to IV) of lasers, including three subclasses (IIa, IIIa, IIIb). The higher the class, the more powerful the laser. Consumer laser products include classes I, II and IIIa and lasers for professional use may be in classes IIIb and IV. Laser pointers are included in Class IIIa. The FDA requires warning labels on most laser products, including the power output and the hazard class of the product. Some lasers are strictly for use by medical, industrial or entertainment professionals and can only be used by a person with a license and training.

From January 1 to June 30 2015, there were more than 400 laser incidents reported to CAA. Heathrow had the most incidents by count, with 48 in the first half of the year. (This is actually fewer incidents per month than last year, when there were 168 total Heathrow laser reports for all of 2014.)
By proportion of laser incidents to air traffic volume, there was a higher frequency of attacks at regional airports such as Birmingham, East Midlands, Leeds Bradford and Newcastle.
The British Airline Pilots’ Association (BALPA) on November 2015 released the results of a survey of its pilot members, showing that 50% had reported a laser/aircraft incident during the period from November 2014 to November 2015.
From the Guardian and the Express. The CAA and BALPA statistics were released along with news of a British Airways pilot who reportedly suffered severe retinal injury from a spring 2015 exposure to a “military-strength” laser.
Except for the involvement of multiple helicopters in New York City, the twenty November 11 overnight events were actually close to the current 2015 average of the 18.3 reported incidents per night.
It is normal for day-to-day incident numbers to fluctuate. For example, a day later on November 12, there were six incidents according to Slate.
Another example of the variability of daily incidents is shown by the day-to-day numbers for 2014. During the year there was an overall average of 10.7 incidents per day. The graph shows that daily numbers (light line) varied from 0 reported laser incidents to 24. (The dark line shows a 30-day moving average, to help smooth out the data. Day-to-day figures for 2015 are not yet available.)
The U.S. Federal Aviation Administration made a Facebook post describing the November 11 incidents:
More than 20 aircraft were struck by lasers from the ground last night while flying over cities across the United States. Three laser strikes were reported in the New York City/Newark, N.J early in the evening, followed by three incidents in Texas, where jets were struck while preparing to land at Dallas Love Field. By late evening, pilots reported laser incidents in:
New York/Newark; Dallas; Jamestown, NY; Oakland, CA; Covington, KY; Danville, KY; Palm Springs, CA; Salt Lake City; Los Angeles; Albuquerque; Detroit; Ontario, CA; St. Petersburg, FL; Springfield, IL; San Juan, PR; Sacramento
None of the pilots reported injuries. Nevertheless, shining a laser at an aircraft is a federal crime that the U.S. vigorously pursues. Lasers distract pilots from their safety duties and can lead to temporary blindness during critical phases of flight, such as takeoff and landing. In some cases in the past, pilots have reported eye injuries that required medical treatment.
As of Oct. 16, the total number of laser strikes around the U.S. this year was 5,352.
Media stories that referenced the incidents included the following headlines and leads:
With new flurry overnight, laser strikes on aircraft hit record pace, USA Today
“Laser strikes on planes are growing even as the federal government enacts tougher penalties for people caught shining the devices. Overnight Thursday federal authorities fielded reports of more than 20 laser strikes on aircraft, adding to an already record-breaking number of strikes this year.”
Overnight outbreak of lasers pointed at aircraft, CBS Evening News
“The FAA says 20 aircraft were targeted by people with bright laser pointers Wednesday night in cities across the nation. Kris Van Cleave reports on the surge in these types of incidents.”
FAA: Lasers beams hit more than 20 aircraft overnight, Washington Post
“Federal authorities have launched an investigation after numerous aircraft were hit by laser beams Wednesday night. More than 20 aircraft were struck while in flight over at least 16 U.S. cities, according to a statement from the Federal Aviation Administration. Authorities said three strikes were reported to the FAA in the New York City area, followed by three in Texas that hit jets that were preparing to land.”
Lasers hit 20 aircraft flying in U.S. overnight - FAA, Reuters
“Dangerous beams from handheld lasers struck 20 aircraft flying over the United States and its territories overnight, among the nearly 5,400 laser hits in the nation so far this year, the Federal Aviation Administration said on Thursday. No injuries were reported in the incidents, which took place from New York City to Sacramento, and resulted in at least one arrest. Authorities said the incidents did not appear to be linked to each other.”
6 aircraft hit by lasers in New York, Dallas on Wednesday, Fox News
“Three news helicopters in New York and three planes near Dallas were hit by laser beams on Wednesday, according to the Federal Aviation Administration. Pilots for choppers flying for CBS New York, WNBC and WABC each described seeing a laser in their cockpit while flying over a scene in Park Slope, Brooklyn, CBS reported.”
High Number Of Laser Strikes In One Night Has Pilots Uneasy, CBS Sacramento
“The Federal Aviation Administration is looking into a series of laser strikes on aircraft across the country, including a possible strike at Sacramento International Airport. The exact details of that reported laser strike have not been made available yet, but for pilots these little beams of light are a huge concern. It was a busy night for law enforcement and air traffic control across the nation, with more than 20 pilots reporting laser pointers aimed at their cockpits.”
Such misdiagnosis has medical and financial consequences from the additional diagnostic workups and DNA sequencing used to detect hereditary genetic disorders such as rod monochromatism, Stargardt disease and occult macular dystrophy.
In addition, the paper describes five cases of where children using laser pointers experienced blurry vision and had eye injuries. “In some cases, the vision was as poor as 20/80, which is bad enough to fail a driving test,” said researcher Dr. Stephen Tsang, who is affiliated with Columbia University and NewYork-Presbyterian Hospital.
Dr. Tsang and his colleagues noted damage patterns similar to tree branches on the children’s retinas:
They suggest that eye-care professionals should ask patients with such patterns if they have been using lasers. Because children may be hesitant to talk in front of their parents, the researchers also suggest talking to a child alone.
A Columbia University press release noted “Since the publication about the five patients, the researchers have seen several more children with laser-induced eye injuries, suggesting that these cases are not isolated phenomena.”
From Columbia University Medical Center Newsroom, Nov. 5 2015. The Ophthalmic Genetics article “Laser induced photic injury phenocopies macular dystrophy” is not yet online as of this date, but can be found at the journal’s website.
Based on trends in the years 2010 through 2014, this means that at the end of 2015 there could be between roughly 6,500 and 7,100 reported incidents. (The range is because in some years, the yearly total was between 1.28 and 1.37 times the Jan. 1 - Oct. 9 total.) We estimate that 2015 is likely to have roughly 6,850 incidents. This would be 176% of the 2014 total of 3,894 incidents.
Stated on a daily basis, the number of reported incidents is expected to rise from 10.7 per day in 2014 to between 18.0 and 19.3 per day in 2015.

Herman was later quoted as saying “When you can see all these lasers everywhere, it just kind of represents everything that goes on in the lives of 18- to 22-year olds. We needed everybody to shut all that out and bring all that into one common focus.”
The tactic may have helped; the Houston Cougars went on to beat the Vanderbilt Commodores 34-0 on October 31 2015.

Negroni began the segment by noting that laser incidents are “truly a menace and it’s not to be taken lightly.” She said offenders “don’t watch the news, they don’t read the paper” and thus “they need to be reached out on their level. And that level is like a Facebook level or a Twitter level, where people are actually going to learn.”
She concluded that “it’s just time for the establishment to get on board, before something really terrible happens.”
Negroni has written aviation articles for publications such as the New York Times and Smithsonian Air & Space, is an on-air expert for ABC, CNN and NBC, and has a book on mysterious aviation accidents coming out in 2016. She previously wrote an article for RGN critical of FAA laser publicity efforts entitled “No let-up in laser attacks on airplanes” published December 13 2013, and a blogpost on the same topic on August 28 2014.

According to the Kaua’i Island Utility Cooperative, “The lasers are similar to common laser pointers and use a narrowly focused green beam of light. Because the beams are parallel to the ground and because the installation is not in designated air space, the lasers do not pose a hazard to aircraft or passersby.”
Lasers create a “light fence” to illuminate transmission poles and power lines in ‘Ele‘ele, Kaua‘i in August 2014.

DICKERSON: So, the final question, Sully, I want to ask you about these reports about near misses from drones and commercial airlines. How dangerous is that?
SULLENBERGER: Well, because they are easy to get and they're relatively inexpensive, these devices are becoming ubiquitous. And that is true not just of drones, but of laser pointer attacks. And so it allows people to do stupid, reckless, dangerous things with abandon. I am heartened that the aviation and the legal authorities have raised the penalties for doing these things. Unfortunately, the essential element that is still missing is the certainty of prosecution, because it has been difficult to catch them in the act. This must stop.
DICKERSON: Very quickly, though, what could possibly happen, though, with one of these drones? I mean, how bad could it get?
SULLENBERGER: Well, we have seen what a six-pound or an eight-pound bird can do to bring down an airplane. Imagine what a device containing hard parts like batteries and motors can do that might weigh 25 or possibly up to 55 pounds to bring down an airplane -- it is not a matter of if it will happen. It is a matter of when it will happen.
Sullenberger successfully ditched U.S. Airways Flight 1549 in New York’s Hudson River in January 2009, after multiple bird strikes caused both engines to fail just after takeoff from LaGuardia Airport. Since 2011 he has been a CBS news aviation and safety expert commentator.

The glasses block three laser wavelengths, in the red, green and blue regions. According to Dr. Perricone, “The real challenge was how do you block out red, blue, and green without changing the color discrimination. It’s critical a pilot sees color. He has to look at his instruments, he has to look at runway lights and a lot of other signals.”
A July 30 2015 news story said the glasses “have been manufactured and are ready for purchase, costing $400 a pair.”
Dr. Perricone was quoted as saying that if pilots are required to wear glasses like these, “then this problem will go away. No one is going to throw rocks at a window that won’t break.”
One pilot said that lasers have been pointed at him “at least 10 times in the past 3 years.”
A CJME news story notes that “pointing a laser at planes could land those responsible in hot water under the Canadian Aviation Regulation Act. Potential penalties range from fines of $3,000 to multi-year probation sentences and incarceration. Charges could also include mischief, assault with a weapon and assault of a police officer.”
From CJME.com and 620CKRM.com
Delaware Online reported from the event that “[l]asers have been a point of contention in Ocean City [MD] for years, with the council deciding to ban the sale of them last summer, and make it illegal to possess a laser pointer in public. Similar laws have gone into effect in New Jersey, but the Coast Guard hasn’t seen a decrease in laser strikes, [Lt. Shawn] Glavan said.”
According to The Dispatch, “Coast Guard Station Atlantic City, where [Glavan’s] MH-65 Dolphin [helicopter] is based, handles around two or three incidents a week involving individuals shining lasers on the aircraft. Coast Guard Air Station Atlantic City’s response area covers a large swath of the mid-Atlantic including Ocean City and as far south as Chincoteague.”

The study, reported in the July 2015 American Journal of Ophthalmology, looked at 17 eyes of 17 patients at two institutions, between January 2012 and May 2014. Most were youths (mean patient age 18 years; range: 11 to 30 years old). The eyes were exposed to blue laser light for less than one second, at a mean distance estimated to be about 1 meter from the laser. The time from exposure to the patient visiting the hospital for treatment ranged from two days, to almost 500 days.
Patients were given a full ophthalmic examination, including fundus photography, macular spectral-domain optical coherence tomography, and fundus fluorescein angiography.
The macular holes ranged from 0.17 millimeters to 0.62 mm, with a mean diameter of 0.35 mm.
In 14 of the eyes, surgeons went deep into the eye and removed vitreous gel (a pars plana vitrectomy); this removes clouded gel that may contain blood from the injury. At the same time surgeons also did a procedure called “internal limiting membrane peeling,” which uses an instrument to make a break in the membrane which is then peeled away with forceps.
In 11 of the 14 eyes, the operation completely closed the macular hole. Of the other three unoperated eyes, the eye with the smallest macular hole spontaneously closed.
Before the operation, the mean Snellen best corrected visual acuity (BCVA) was 20/210, or about 1/10th the normal visual acuity; the range was from 20/30 to 2/200. After the operations, the mean BCVA was 20/62 (range: 20/20 to 4/200). These statistics included all eyes (the 14 operated eyes and the three unoperated ones).
The authors concluded “Full-thickness MH can result from momentary exposure to high-power handheld laser devices. While spontaneous closure may occur in rare cases, most cases require early surgical intervention. Vitrectomy may be successful in closing the macular hole with visual acuity improvement in most of the cases.”
From the abstract of the study by Alsulaiman SM, et al., “Full-Thickness Macular Hole Secondary to High-Power Handheld Blue Laser: Natural History and Management Outcomes” in the American Journal of Ophthalmology, July 2015 Vol. 160, Issue 1, Pages 107-113.e1.
Note: Other studies have been published based on this data, an August 2013 LaserPointerSafety.com story about the first study is here.
Based on past years’ trends, this means that at the end of 2015, there could be between about 5,600 and 7,400 incidents. (The range is because in some years, the second half of the year had 2.04 to 2.71 times the number of incidents in the first half.) We estimate 2015 is most likely to have about 6,300 incidents. This would be a 62% increase over the 2014 total of 3,894 incidents.
Stated on a daily basis, the number of incidents is expected to rise from 10.7 per day in 2014 to somewhere between about 15 and 20 incidents per day in 2015:

Helping Canadians better understand the dangers lasers pose to aircraft
The Honourable Alice Wong, Minister of State (Seniors), on behalf of the Honourable Lisa Raitt, Minister of Transport, today launched the Government of Canada’s safety awareness campaign for lasers. The national campaign will help Canadians better understand why pointing a laser at aircraft is not a bright idea.
The first phase of the campaign, unveiled today in collaboration with the Vancouver International Airport, the RCMP, and NAV CANADA, provides the public with an easy to follow infographic, which clarifies the dangers and consequences of pointing lasers into airspace and how incidents can be reported. This summer, the second phase of the campaign will include digital advertising, awareness videos and a direct mail campaign near three major airports.
Transport Canada has also launched tc.gc.ca/NotABrightIdea, which provides Canadians with the information they need to better understand the dangers of pointing a laser at an aircraft.
Transport Canada is working closely with police, other government departments, and the aviation industry to protect pilots, passengers, and people on the ground. If you see a laser pointed at an aircraft, report it to your local police.
- The number of lasers pointed at aircraft is rising in Canada. In 2014, there were 502 reported incidents – a 43% increase since 2012.
- Aiming a laser at an aircraft is a federal offence. If convicted under the Aeronautics Act, an offender could face up to $100,000 in fines, 5 years in prison, or both.
- Canadians can join the conversation and learn more by using the #NotABrightIdea hashtag on Twitter.
The hobbyist, with the username “styropyro,” wrote on YouTube: “Just finished building my 40W(!!!) laser shotgun!!! The output of this laser is complete insanity, and is made up of 8 parallel 5W laser beams totaling to 40W. The parallel beams are manipulated with lenses, sort of like how a choke modifies the spread of a shotgun blast. The massive diode array is powered by a huge lithium polymer battery pack (capable up dumping 250A) and the laser array is regulated by a whopping 24 LM317 drivers. This is definitely the craziest thing I have ever built, but I hope to beat this invention with something even crazier before too long.”
In the video narration, he said “I just built something so crazy that I’m almost afraid to use it” and “There is no, no good reason for anybody to own something this powerful. But because it wasn’t illegal for me to build, I decided to build it anyway.” The video then goes on to show the beam popping balloons, and burning paper, a ping-pong ball, and other materials.
Styropyro had previously posted other videos with titles such as “Homemade Lightsaber!?! MASSIVE 3W Handheld Laser Torching Stuff!!”, “My Homemade 6W Laser Sword!!!” and “Homemade Death Ray Laser DRONE BOT!!! Remote Controlled!!!”

The laser is full color (red, green and blue combined) and is said to be harmless. The system was developed primarily as a vision aid for persons with visual defects. According to the news story, the image does not require focusing and is projected through the eye’s lens directly onto the retina.
The story notes that “the basic idea of projecting imagery onto a retina via laser has been around for decades, but miniaturizing the optics to realize a wearable form factor had been difficult until recently.”
A Fujitsu spinoff called QD Laser helped develop the glasses. They expect to begin selling them in March 2016 in Japan, Europe and the U.S. for about USD $2,000.

80% of the cases involved aircraft on approach, 15% involved aircraft taking off, and 5% happened during cruise.
The commander of the border police said he has never been able to identify the laser perpetrators. The fact that incidents occur in the dark, “coupled with the fact that a laser pointer can be easily hidden, makes it impossible to identify those responsible, unlike those who throw stones from the flyover. We think they are guys who do not realize the severity of what they do."

It was unclear from news reports whether the warning was sent directly to students at school, or if the warning came only as part of a May 4 2015 news story on the website Health24.com. A May 11 search of the Gauteng Department of Education website did not show any announcements, notices, documents, or other information warning about laser pointer hazards.
The spokesperson said that at least two children had permanent eye damage from lasers. One case cited was a South African 11-year-old boy who looked into the laser light after one of his classmates was playing with it. His mother said “He now has a blind spot right in front of him, but still see the sides of the eye [sic].” This case was reported in April 2015. The other South African case involved a child who aimed a laser’s light into his eye and had permanent damage.
Gautang is the most populous province in South Africa. It contains the cities of Johannesburg, Pretoria, Midrand and Vanderbijlpark.
From Health24.com: Story about the warning to learners, and story about the 11-year-old boy being injured.
It began by noting that in 89 of the 93 reported arrests last year for laser strikes against aircraft, the offender was male. The article quoted a New York laser safety officer, John Zelenka, as saying he has never seen a female playing with lasers.
A developmental psychologist was quoted as saying that lasers appeal to a masculine perspective. Patrick Murphy (editor of LaserPointerSafety.com) told the Journal “For a lot of guys it’s like, ‘The bigger the laser, the more visible, the more of a man I am.’”
Author Sophia Hollander then noted that the prices of a 20 mW laser dropped from $239 in 2004 to $8 in 2015.
She examined the similarity of “Star Wars” lightsabers and lasers, quoting experts on the appeal to males of a weapon that can “throw your influence.”
The online article was illustrated with photos from a lightsaber combat class held by the group New York Jedi. Actual lasers were not used in the class due to the potential hazards.

In addition, volunteer Kelli Halston Hoversten suffered two permanent eye injuries during the climactic “Man Burn” in 2014. Her left eye was permanently blinded by a handheld laser, and her right eye was partially blinded by a vehicle-mounted laser. (The injuries significantly affected her. Hoversten “lost her job as an arborist because they can’t insure her now” and she no longer rock climbs or ice climbs recreationally due to the loss of depth perception. She is allowed to drive but “just barely” since her central vision is blocked.)
According to an article about the policy change in the Reno Gazette-Journal, Hoversten will attend the 2015 Burning Man event, in part because of the new laser policy.
The Burning Man ban on handheld lasers applies even to low-powered laser pointers less than 5 mW in power. In a separate blog post comment, Burning Man press official Will Chase wrote: “Because of the difficulty in discerning the difference between dangerous and non-dangerous handheld lasers — and because you don’t want to be wrong — it’s been decided to prohibit all handheld lasers.”
The new webpage with the laser policy also noted that the restriction on handheld lasers “is in line with nearly all major festivals and events in the United States and Europe.”
Non-handheld lasers are still allowed at Burning Man if they are on art installations, “DMV Mutant Vehicles,” or are in theme camps. Such lasers must be disclosed on the art, vehicle or camp application. An Event Safety Officer will review the applications; only safe uses will be allowed.
The first version being sold on Kickstarter contains two Class 2 (<1 milliwatt) 635 nanometer red laser modules. The module on the left (in the photo above) is suspended inside the TV-remote sized SteadyLaser. It provides the stabilized beam. The other laser is non-stabilized, like a standard laser pointer. In the final Kickstarter version, the user can choose either either the stabilized beam or the normal beam, but — for safety reasons — not both at once.
This is a 2-second exposure, from a Kickstarter video, showing both beams being emitted simultaneously in order to demonstrate the stabilization’s effect. The line traced by the stabilized laser is up and to the right of the non-stabilized laser’s line.
Pricing for the initial run of 1000 SteadyLasers is approximately $150 each. It is promoted on Kickstarter solely for presentations in professional locations such as businesses, schools and courts. The primary benefits are claimed to be minimizing distraction, and reducing the appearance of nervousness when using a laser pointer in presentations.
The Kickstarter page first went up approximately April 10 2015. As of April 13 there were 6 backers pledging $960. The goal is to get $150,000 in backing by June 9 2015; otherwise the laser will not become a product — or at least, not through Kickstarter.
Regardless of the Kickstarter outcome, the inventors want to license their patents to current laser pointer manufacturersd.

Commentary from LaserPointerSafety.com
There could be concern over a handheld laser that can remain steady on a target. If aimed at an aircraft’s cockpit, the beam would be able to stay in a pilot’s vision longer than a standard, non-stabilized laser pointer.
Because of this potential hazard, LaserPointerSafety.com contacted co-inventor Jeff Wilson, who kindly agreed to add an aviation safety warning to the SteadyLaser’s labeling, with text such as “Do not aim at vehicles or aircraft. This is hazardous and illegal.”
The first-generation SteadyLaser has low power (1 mW) and low apparent brightness (635 nm red, which appears only 25% as bright to the human eye as the common 532 nm green laser). Assuming a 1 milliradian divergence, the SteadyLaser is an eye hazard to 23 feet, can cause flashblindness up to 55 feet from the laser, can cause glare up to 245 feet, and would be a distraction to pilots (brighter than other city and airport lights) up to a half mile from the laser.
However, if future versions had more power — up to the U.S. FDA’s limit of 5 mW for laser pointers — and used a 532 nm green laser, then the hazard distances would increase as follows: eye hazard to 52 feet, flashblindness to 245 feet, glare hazard to 1,097 feet, and distraction hazard to 2.2 miles.
Commentary from LaserPointerSafety.com: There have been many pilot claims of eye injuries caused by laser pointers aimed at their aircraft. FAA has investigated some of the most serious claims. In 2011, a person knowledgeable about these studies told LaserPointerSafety (on background): “I haven't seen anything that convinces me that any of the FAA incidents are true injury. I haven't seen any convincing evidence of delayed laser lesion effects. I do know that headaches and eye pain and photophobia and light sensitivity have been reported and associated with laser illumination. I have seen nothing convincing me that there is real cellular, tissue injury.”
There have been a few cases (<10?) of temporary eye injury, where the eye healed. This is similar to how skin can heal after a sunburn. In all of these cases, the pilots returned to flying.
There have also been cases of reported laser injury to the cornea. This is the transparent surface of the eye. Visible laser light passes right through and is not absorbed. The cause of these reported “laser” injuries is the pilot rubbing his or her eyes too vigorously, causing painful scratches in the sensitive cornea. Any damage from a visible laser beam would be on the light-absorbing retina.
Note that FAA limited its statement to commercial pilots. There may be military pilots in conflict zones who have been injured by laser weapons. If so, this information would be classified. Due to the seeming lack of urgency with FAA and U.S. military, any such injuries would not seem to be a threat to commercial pilots in the U.S.
Here are lists of all LaserPointerSafety.com news items tagged with the keyword “eye effect or injury”: aviation injury incidents, non-aviation injury incidents, other eye injury stories.
LaserPointerSafety welcomes any documented cases of pilot eye injuries. Contact us with the links etc., and also contact FAA so they can be aware of the cases.
Schumer made the announcement at a Sunday press conference in his Manhattan office, along with four commercial airline pilots who had been illuminated by laser light. One pilot, Gabe Rubin, said he knew of a pilot who “suffered severe eye damage from a green laser pointer [and] will never fly again.”
Schumer said “Green lasers are the weapons of choice being used for evil purposes. We know terrorists are always looking for areas of weak points.”
He is focused on green pointers because they are apparently preferred by pranksters because the green light travels farther, and “because the light spectrum of green is more easily absorbed by the retina and then causes more damage”, according to the senator.
In 2012, Schumer wrote a letter to the U.S. FDA saying that laser pointers’ power should be less than the current 5 mW limit, that FDA should restrict more powerful Class 3B (5-500 mW) and Class 4 (500+ mW) lasers, and that FDA should require warning labels about aiming at aircraft.

Additionally, there were 312 laser incidents that occurred outside the U.K. to U.K. operators.
In 2014, the top four most frequent incident locations were London/Heathrow (168), Manchester International (107), Birmingham (92), and Leeds Bradford (81). London/Gatwick and Glasgow were tied for fifth place, each with 64 reported incidents.
CAA published a PDF report with more detailed figures, including a monthly breakdown of the most frequent laser incident locations in 2014, and monthly & yearly totals for 2009 through 2014, and overseas (non-U.K.) incidents occurring to U.K. operators.
From the CAA PDF report dated February 2 2015. Note: There is a discrepancy where one table lists a total of 1,440 incidents in 2014 while another lists a total of 1,442. We have used the larger figure in this story.
