NYE laser show leaves 200 students in Andhra with eye irritation
The children's eyes began watering and had turned red when they got up the next morning.
Around 40 students of a private school in Andhra Pradesh's Parvathipuram village in Vizianagaram district had to be given medical treatment, after their eyes began to swell on Monday morning [January 1 2018].
The 40 students, along with 200 others, began complaining of irritation and pain in their eyes, after they were reportedly exposed to lights and lasers during a show, as part of the school's New Year's Eve celebrations.
The children's eyes began watering, and had turned red when they got up the next morning.
As the children began complaining, worried parents staged a protest and demanded answers from the school.
Following this, doctors rushed to the school and administered first-aid, before assuring those who had gathered, that the kids would not lose eyesight.
“We prescribed eye drops and ointment for the affected children,” a doctor told the Times of India.
Meanwhile, Vizianagaram district Collector Vivek Yadav was informed of the incident, and directed the Revenue Divisional Officer (RDO) of Parvathipuram, P Sudarsan Dora, to visit the school along with Mandal Educational Officer P Krishna Murthy.
Circle Inspector G Rambabu also visited the school along with the officials, and spoke to the children, to collect more details regarding the case. Further details are awaited.

From Luton Today
None of the seven crew members were reported to be injured or affected by the light.
According to a news story, “Last year the Port of Cromarty Firth also complained to police after laser pens were shone into the waters of the firth. One worker had to receive medical treatment when a pen was shone directly into his eyes.”

The incident happened on November 26 2017. A College Place resident later confessed to using the laser pointer. The 43-year-old woman said she “inadvertently” aimed the laser at the officer. Police said the laser was “Class III.”
The unnamed woman may be charged with unlawful discharge of a laser at a law enforcement officer in the performance of their duty, a Class C felony which has a punishment of up to five years in prison and up to a $10,000 fine.
The laser pointer
Close-up of the laser pointer label
Note from LaserPointerSafety.com: Visible light travels through the clear cornea — it is not absorbed by corneal tissue. It is essentially impossible for a handheld laser’s visible light to be able to cause corneal damage to a moving target many yards away. While certain green lasers can also emit infrared light, it is extremely unlikely that the IR was strong enough to cause damage under the specified conditions. When corneal damage is seen after an unwanted laser pointer exposure, this is due to the person rubbing their eyes too vigorously. More information on evaluating laser injuries is here.
Motorists impeded by green laser light, Mount Pleasant
Three motorists, including one police officer, were travelling on Mackay Bucasia Road (Mount Pleasant area) when their eye-sight has been impeded by the deliberate shining of a green laser light from a near-by residence situated on the eastern side of the roadway.
The incident involving the police officer occurred at approximately 9:26pm on November 11 as the officer was travelling in a marked police car, travelling in-bound towards Mackay. The officer’s eye-sight was impeded twice by the shining of the green laser light. Police had received two reports of a similar nature from other motorists in the same time frame.
Despite patrols conducted on foot and by vehicle the address where the green laser light was activated from was not identified at the time. Police are conducting further investigations. Any one who may have information linked to these incidents is encouraged to contact the Mackay police station on 0749 683 444 or you can call Crime Stoppers on 1800 333 000 any time of the day and provide information anonymously. The police reference number is QP1701988362.
Actions such as these have the ability to temporarily effect the eye-sight of the driver of a vehicle – which can potentially create life endangering circumstances.
An optometrist who examined the boy said “It was clear after taking a close look at Carlo’s eyes that he had suffered some sort of damage. I could see there were slight burns to the surface of the eye [cornea] and the retina, the light sensitive tissue at the back of the eye, had been damaged.”
According to the optometrist, the boy is likely to need glasses when he is older due to the “irreversible” damage.
Carlo’s mother said “I had no idea laser pens could do so much damage to the eyes. If we had known, we’d never have let him buy one. The damage was slight when it was detected so Carlo hadn’t complained of any issues, but thank goodness it got picked up when it did.”

On September 12 2017, a boy turned around and aimed the laser at the girl’s face. She covered her face but he deliberately aimed at her eyes. When she arrived at school, the girl told her teacher that her eye was sore and blurry. It remained that way throughout the day.
She went to an emergency center that night, and an ophthalmologist the next day. The prognosis was that there was no physical damage and her vision should improve.
About a week later, a local optician examined her and said there was damage to her peripheral vision on the left side, and it was likely to be permanent.
The girl’s father told The Press and Journal, “I was angry. I was shocked on Saturday, I was hoping it would get better. My daughter was upset. It has knocked her confidence. What I’m really bothered about is the availability of these pens. These laser pens are a danger and people should be aware. I’m intending to write to local MSPs and the MP about it. I don’t think any children should be able to buy them. You can buy them in supermarkets and on Amazon – I don’t think that’s right. I think the legislation has to be changed.”
A survey of UK ophthalmologists reported more than 150 incidents of eye injuries involving laser pointers since 2013, the vast majority of these involving children.
From an October 12 2017 article in The Press and Journal
The undated attack was discussed in an October 9 2017 press release from Dr. Valev’s institution, the University of Bath. The goal of the press release was to warn the public about laser pointers which may seem safe but are too powerful and/or emit infrared light in addition to visible light.
Dr. Valev and colleagues tested laser pointers at the university, and found the potentially unsafe conditions.
As part of the press release, Dr. Valev related a laser pointer attack that occurred in his home. He said his daughter was asleep at the time so no light entered her closed eyes. Dr. Valev said “… I got only momentarily dazed, but suddenly everything became red. I was thinking that perhaps I was experiencing a medical condition, but my wife saw someone shining a pointer at me from outside our home.”

US: Calif. teacher loses credentials for, among other things, shining laser pointer in students' eyes
Carlos Cameron Duncan was said to have been aggressive to his students at Euclid Elementary School, to have verbally abused them, and to have used physical force, among other charges. He resigned March 8 2016. His credential revocation was reconsidered and sustained in April 2017.
There was no indication of any claim of injury from the laser pointer shining.

She was treated at a hospital for “extreme burning pain.” She recovered with no lasting damage.

From BBC News
The document lists over 70 incidents. The two which involve prototype hardware that includes, or appears to include, laser light are:
- “After BT4 user study, user advised study lead, that she experienced discomfort in her eye and said she was able to see the laser flash at several points during the study. Study lead referred her to optometrist and secured prototype unit for analysis.”
- “Employee reported eye pain after working with new prototype, thought it may be associated with use. He noticed that the security seal on the magenta (outer) case had been broken and had thought the unit may have been tampered with.”
Gizmodo wrote that “a source inside Apple speculated that this [March 2] injury may have something to do with an augmented reality product Apple may be testing, something like glasses with an overhead display.”
Another tech blog, SlashGear, speculated on how Apple might be using lasers in or near eyes: “There are several possibilities as to how the lasers mentioned in one of the incident reports might be involved in that, depending on the technologies Apple is using. For instance, laser projection – where graphics are created directly on the eye using a system of targeted laser light – has been used by several companies wanting to make a daylight-visible UI. Another alternative, and possibly a more likely one, is laser eye-tracking. That relies on using lasers to monitor eye movement in real-time, so that the wearer’s direction of gaze can be calculated. Such a system would be able to figure out what the user was looking at and potentially control a user-interface that way.”

On April 17 state police announced that Jonathan Edward Rayner was arrested and a laser pointer was retrieved. Rayner had been a passenger in another car on the highway. The 32-year-old man was charged with assault with a dangerous weapon, and with “assaulting-resisting-obstructing a police officer.” Both assault charges are felonies. The maximum penalty is four years in prison on the dangerous weapon charge, and 20 years in prison for assaulting a police officer.

The incident happened on eastbound Interstate 94 in Wayne County at about 8 pm. The trooper was taken to a hospital “with vision problems and headache.” Later that day, state police tweeted “His vision has returned and he has been cleared. Other than a serious headache he should be back to work.”

Raden also pleaded guilty to reckless endangerment in Island County Superior Court. He was ordered to serve 15 days in jail, perform 240 hours of community service, pay $3,740.89 in restitution to the master and chief mate, and serve 24 months probation.
On April 26 2016, the Coast Guard issued a civil penalty of $100,000 against Raden. According to a Coast Guard press release at the time, “Coast Guard officials are seeking civil penalties for violation of a safety and security zone as well as interference with the safe operation of the Tokitae [ferry] while it transited between Mukilteo and Clinton [in Washington state]. The final civil penalty amount [which turned out to be $9,500] will be determined by a Coast Guard Hearing Officer in Arlington, Va.”
A Coast Guard spokesperson told Cyrus Farivar of Ars Technica "Originally there were multiple charges that brought the maximum amount to $100,000 [as] referenced in the original [press] release. Ultimately the hearing officer has the final say and chose to only pursue the one charge for 'interfering with the safe operation of a vessel' and assessed a fine of $9,500."
Raden has previously been in trouble for misusing a laser. In July 2015, Raden and his friend Dillon Reisman, 27, were aiming a laser into house windows in Langley, Washington, in order to “cause alarm to anyone trying to sleep.” When confronted by police, Raden repeatedly aimed the laser beam into an officer’s face. Felony charges were not filed until November 18 2015.
In yet another incident, police said Raden was accused of using a laser and acid as weapons.

The Google-translated headline on a story from Korean website Dispatch.co.kr is “ ‘Fans rage, threatening safety’ … jeongchaeyeon laser beam terrorism”
According to Koreaboo.com, the alleged laser pointer came from an “anti-fan.” This is a concept where people who dislike celebrities will take negative actions against the celebrity or their fans. For example, one girl group member, Gan Mi-Yeon, received “scores of ‘fan mail’ filled with razors … along with pictures of her with her eyes taken out or letters written in blood.” In 2000, a boy band member was given a soda injected with bleach; his mother happened to drink it and was hospitalized.

The accident occurred at about 5:30 am on October 25 2016. Miranda Senters, 18, was driving her new car, bought one week prior, when the driver in front of her aimed a green laser beam over his shoulder towards her. Senters told KGW News “I just kept going back and forth a little bit, trying to keep out of the light.” The laser driver then went behind Senters’ car and aimed into the rear-view mirror: “…he’s shining it from the back of me into my eyes and I couldn’t see.”
Senters tried to get away but the other driver weaved in and out of lanes to keep up with her. While trying to avoid the light, Senters swerved to the shoulder and spun out. The other car crashed into her. A third driver hit a barrier when trying to avoid the stopped vehicles.
The laser car, an older Honda Civic, left the scene. In an Instagram post, state police asked the public to help them find the Civic.

Senters later told KPTV “He had a little laser and was trying to get it through my front window. I went blind because a green laser light — like my eyes still hurt from that, I can still see it…. I don’t understand how it’s a joke. It could have killed me.”
From KGW and KPTV. Thank you to George Palikaras for bringing this to our attention.
Note from LaserPointerSafety.com: This is the first well-documented case we’re aware of where a laser pointer aimed at a driver directly caused a crash. There was a fatal crash in 1998 which was partially blamed on a laser pointer, and an indirect reference to a three-car accident in 1999. There have also been a number of near-accidents and other car-related laser incidents which are listed here.
She was walking on a road, under a railway bridge, in Clydebank when the incident took place at about 10 pm on September 10 2016. The exact nature of the attack — whether money was demanded or if the lasing was random — was not described in news accounts.
The woman was taken to a hospital about 4 miles away. She later reported the assault to the police. News about the attack was not released until a week later.
News reports quoted a Police Scotland spokesperson as saying, “This was a completely unprovoked and senseless attack on this woman, which has left her blind in one eye. The youths responsible must be caught as soon as possible. To point a laser pen at someone is highly irresponsible. Extensive inquiries are ongoing to trace the two boys, with officers carrying out inquiries in the local area and studying CCTV footage to identify them.”
The attack comes just a few days after a man was arrested for aiming a laser pen at a Police Scotland helicopter in Clydebank on September 5 2016.

Northport Police Chief Bill Ricca told LaserPointerSafety.com that the laser beam went into the officer’s face and eyes. The officer was temporarily blinded. He did not feel discomfort, but did go to an eye doctor for an exam which showed no ill effects.
Ricca said that the situation could have been much worse: “If the laser was aimed at the cop’s chest so the cop could see what was going on, I’m sure he might have shot at the kid. We would have had a real bad incident.”

An Internet search of similar “laser pointer guns” turns up a similar lighter costing about $7.00.
From Northport Patch and a September 16 2016 phone interview with Chief Bill Ricca
In a separate interview, one of the authors, ophthalmologist Dr. David Almeida, said these cases are “happening more frequently…. It was previously thought this was a one-in-a-million event. It's still probably a rare-to-uncommon reaction, but it's not a never reaction.”
All four children had foveal laser burns. Three of the children had potentially permanent vision loss. These are the cases:
- A 12-year-old boy looked into a green laser pointer for about a minute. He had decreased central vision in both eyes, with 20/20 vision in one eye and 20/30 in another. His vision and macular condition was found to be unchanged after 7 months.
- A 16-year-old teenager similarly had central vision loss in both eyes, after playing with a green laser pointer for about 30 seconds. He was first examined three days after the exposure, scars and atrophy were found on the retina. Two weeks later his vision has worsened. Visual acuity was 20/40 in both eyes with no improvement.
- A 9-year-old boy looked at the reflection of a green laser pointer in a mirror (essentially the same as a direct beam) for an unknown length of time. His vision was 20/50. He was treated with 1% prednisolone three times a day for two weeks. His vision improved to 20/30, but he still had “persistent abnormalities of the photoreceptors.”
- A 12-year-old boy looked into a red laser pointer for about 15 seconds. He had central vision loss, and 20/70 vision. He was given an injection of bevacizumab, which gradually improved his vision and symptoms. After 1 year, he had 20/20 vision.
The authors noted that laser pointers are more available, that users may not be aware of the dangers, and that some users may use pointers improperly.
Visible lasers less than 5 milliwatts (the U.S. legal standard for a laser to be marketed as a “pointer”) are considered to be generally safe due to the bright light reflex, which causes a person to blink and turn away from a bright light. So one question is why these children were injured by laser pointers.
One reason, according to the authors, is that “children increase their chance to retinal injury by staring at the laser beam without blinking or averting the eye for a prolonged duration.”
Another possible cause is that “the labeling of the power output of a laser point may be different from the device’s actual specifications.” They referred to a study of 122 laser pointers, where 90% of green pointers and 44% of red pointers were above the 5 milliwatt U.S. legal limit.
The study said that treatment options were “limited and also controversial.” Use of corticosteroids has shown “mixed results.” It may be enough to observe a patient over time, since many injuries will stabilize.
The authors recommended that laser pointer hazards “should be communicated to health professionals, school teachers, and guardians in an attempt to raise the public awareness of this emerging public health issue. Unsupervised use of these laser pointer devices among children should be discouraged, and there is a need for legislation to limit these devices in the pediatric population.”

This was the first report of Russian use of a laser to blind, which is prohibited by the United Nations “Protocol on Blinding Laser Weapons”. The protocol bans the use of “laser weapons specifically designed, as their sole combat function or as one of their combat functions, to cause permanent blindness to unenhanced vision, that is to the naked eye or to the eye with corrective eyesight devices.”
From Ukraine Today; original story from Interfax-Ukraine
Lynsey McClure had imported the lasers from a Chinese supplier who said they complied with U.K. regulations limiting laser pens to 1 milliwatt of power. Her brother, who was not charged, sold them in a stall during a school fair in December 2015. The headmaster asked her brother to stop selling the laser, but he continued.
Jonathan Marshall, 7, purchased one of the lasers. It was later found to have an output of 127 milliwatts.
His mother said Jonathan was playing with it at home when the beam went into his eye for “a fraction of a second.” He has a retinal burn which interferes with his vision.
McClure pleaded guilty to nine product safety and consumer protection violations, including selling an unsafe product and failing to disclose the power of the laser.
The case appears to be the first where a person has been prosecuted for an illegal laser sale that led to an injury.

Johnson went to a hospital and had an eye examination the next day. (No results were reported as of November 19.)
Because the bus has cameras, the video will be used to try to identify the perpetrator.
According to WABC, this is the first laser incident involving a New York City bus driver.
From a November 5 news account, it appears the injury occurred on Friday October 30 2015. The boy saw a general practitioner the following Monday, who then referred the teen to Ben Armitage, a Hobart (Tasmania) optometrist.
Armitage said the boy did not feel pain during the exposure, but he immediately lost visual acuity. “His vision is down to about 25 percent of what we call 20/20 vision and unfortunately at this stage it’s unlikely that vision is ever going to recover.”
Retina of one of the teen’s two eyes that were damaged by a self-inflicted laser pointer exposure. The injury occurred near the macula. At the center of the macula is the fovea, responsible for sharp central vision.
The damaged area is still swollen; Armitage hopes that some vision may be restored when the swelling recedes.
An Optometry Tasmania spokesperson warned parents not to allow children unsupervised access to laser pointers “and, in fact, better off trying to warn them off because we’ve just seen in this particular case where the future lifestyle of this young person has been seriously affected.”
From ABC (Australia) News
The 44-year-old driver stared into the laser several times, as he tried to identify the person holding the laser. He suffered blurred vision in his right eye immediately after the exposure, but waited 6 months before having his first complete eye exam.
The exam showed “spot-like retinal pigment epithelium disturbances temporal to the fovea of the right eye, with no abnormalities in his left eye.” The authors stated that “The subjective complaints and objective ophthalmological findings of this patient were consistent and strongly suggested that the repetitive exposure of the eye to the reflected laser spot 6 months previously had caused subtle but detectable injury to the macula.”
The authors concluded with two “Learning points”:
- “We suggest that no laser pointers of any class are made available to children, since they are unlikely to understand the risks of permanent retinal damage.”
- “For the safety of users and the general public, even low-energy handheld laser pointers should not be sold to children.”
The authors did not identify the location of the incident, but it may be Germany since three of the four authors’ institutions were in Germany. Additional analysis and commentary is below (click the “Read More…” link).

This map shows the ferries’ route. The map’s indicated positions of the ferries are from a later time and do NOT show their position during the laser incident.
At about 8:30 pm, the ferry M/V Tokitae (shown below) was approaching the Clinton (Wash.) Ferry Terminal. The captains were at wheelhouses on opposite ends of the 362-foot-long ferry. The one piloting the vessel was hit first, and suffered injuries.
According to Washington State Ferries Port Captain Jay Mooney, the man had “third-degree burns on his eyelid and his vision is still not quite back at 100 percent.” (A first-degree burn occurs only on the surface of the skin. A third-degree burn “extends to all layers of the skin,” according to the Wikipedia “Burn” article.)
The blue laser beam came from the slightly smaller ferry M/V Kitsap, which was traveling in the opposite direction.
A Kitsap deckhand had seen two men with the laser, and reported it to a Washington State Patrol trooper after arrival at the terminal in Mukilteo. One man told the officer that “it was a new toy and he was shining it at the water and didn’t mean to shine it at the vessel,” according to a WSP spokesperson. The trooper confiscated the laser pointer, shown here:
The spokesperson said “This is not a typical laser you’d see in a classroom or office setting.” She referenced the manufacturer’s packaging which says to use safety glasses, to not aim it at faces, and that it could light a match if held on target long enough.
A similar-looking laser sold by Lasers-Pointers.com is said to be 5000 mW (5 watts) and costs less than $200:
The two captains exposed to the laser light missed one day of work. The suspect who had the laser has not yet been charged, as of October 29 2015. Prosecutors are determining what charges would be appropriate.
UPDATED - November 9 2015: No arrests have yet been made and no charges have been filed, more than two weeks after a suspect was picked up. This is due in part to determining what jursidiction applied, since the laser incident took place on ferries in waters between different Washington state counties. Another difficulty was determining what charge to file. A KIRO radio story also noted the limitations of the U.S. Food and Drug Administration, which regulates lasers. While FDA attempts to block some high-powered lasers, imports can get through. And, “there aren't any penalties for buying or owning those illegally high-powered devices, nor are there requirements for training for non-medical, non-industrial devices.” From MyNorthwest.com
UPDATED - April 18 2015: 27-year-old Mark Raden was charged with assault in the third degree, for aiming at the ferry captains. In addition, he has a previous history of run-ins with law enforcement over laser misuse. Details are here.

Italy: Prosecutor investigating manslaughter charges in three cases of eye damage to children from laser pointers
The cases were reported in mid-September 2015 by the St. Ursula Ophthalmology Hospital in Bologna. One of the children was 10; the other two were 13.
The injuries were caused by laser pointers bought by their parents (in two cases) or grandmother (in the third case) in markets in Florence or Bologna. One child had a slight loss of vision, another had significant loss in both eyes, and a third has almost lost his sight and is legally blind.
A public prosecutor, Valter Giovannini, has opened an investigation for aggravated manslaughter against unknown assailants. This seems to indicate that in all three cases, the laser pointer bought by or for the children was used against them by another person.
As a result of the report, Carabinieri NAS (Nuclei Antisofisticazioni e Sanità or “Anti Fraud Squad”), a special police force operating under the Italian ministry of health, seized fifteen illegally-sold laser pointers.
The hospital warned the public not to purchase green laser pointers sold “on the street, in the stalls and fairs.” A spokesperson said higher-powered pointers such as those aimed at players in stadiums were to be avoided. Professional laser pointers used in lectures should not be a problem.

According to the Covington News, the photographers told police that the laser light could possibly damage their camera sensors; they also “complained of headaches and said their eyes were starting to dilate.” Emergency medical responders told them “to take Tylenol for their headache.”
Because the local District Attorney’s office said that using a laser pointer was not a criminal offense (except when aimed at a law enforcement office or airplane), the photographers were told that it was a civil matter. No criminal charges were filed.

On April 16 2007, Jacob Keating stopped his train to get a trespasser off the tracks. A group of gang members attacked Keating and the train’s conductor with rocks. The jury found Amtrak negligent, as they did not provide a safe work environment. The area had been known to the company as “a party place” for years; Amtrak did not repair a fence or put up lighting to reduce trespassing.
According to the Sacramento Bee, “Along with the beating, the panel also held Amtrak liable for an incident in 2010, after Keating had returned to work, when someone in West Sacramento flashed a laser pointer into his engine compartment. Keating testified that he thought he was about to be shot and that the laser flash ignited a new round of post-traumatic stress disorder.”
Jurors assigned 6% of the blame to Keating, and 94% to Amtrak.

A 12-year-old Austrian boy has suffered "massive and lasting" damage to his eyes after playing with a laser pointer, with his vision reduced by 60 percent, doctors said.
"We think that he was playing with a mirror and that the rays were reflected," said Yosuf El-Shabrawi, chief doctor at the Klagenfurt am Wörthersee clinic in Carinthia, southern Austria.
"His injuries cannot be treated. We can only hope that the worst of the injuries heal themselves and that his condition improves," El-Shabrawi said in a statement on Tuesday.
The boy's father bought the laser pointer on the Internet where it was advertised as a toy for playing with cats.
After a week the boy, named as Lukas, complained of a constant black mark in his field of vision.
The laser pointer in question was labelled as "Class 2" with an output under the European Union legal limit, but it lacked a so-called EN standardisation certificate, El-Shabrawi said.

DeVaul’s colleague was working as a volunteer when she was struck in the left eye by a “high-power, hand-held green laser, most likely a 1W 532 nm toy from China”.
Burning Man took place August 25 through September 1, 2014, at Black Rock Desert in northern Nevada. As of the September 5 post, DeVaul said the woman “still has not regained vision in her left eye and it is possible that she never will.”

The injured person is from Romania. He was hit in the left eye for 1 second or less from a distance of about 2 feet (~60 cm). He saw a dot in the center of his left eye and could not read properly with that eye. He went to an eye doctor who said there was a small retinal burn. After four days he said the vision improved a bit. He was scheduled for a follow-up exam one month after the injury date.
He asked LaserPointerSafety.com about any possible outcome and treatment. Experts we consulted said his symptoms and vision will probably improve. They suggested a non-steroidal anti-inflammatory drug (NSAID) such as ibuprofen or indomethcin. More aggressive treatment such as steroids (orally or injected into the eye) have been done with “often good” results. The side effects of steroids should be considered. They also indicated that the follow-up examination is important.
The laser was marked “<3000mW”, “Wavelength 532nm +/-10” and “Class IIIb Laser Product”. The label is incorrect, since Class IIIb is between 5 and 500 mW. A laser that is in the thousands of milliwatts would be Class 4.
The laser appears to be a “JD-303” from China; a link is here. The cost is US $5-7 per laser in a minimum order of 30 pieces. (They can supply up to 20,000 lasers per week.) It has a nominal power of 1 watt. The Alibaba web site does say “This is not a toy for your children, this is a high intensity laser pointer for adults only!”

According to the abstract, “Clinically, three children had an acute vitelliform-like maculopathy which resolved to leave sub-foveal retinal pigment epithelium changes with reduced vision. One case was complicated by a choroidal neovascular membrane.”
- Case 1 was of a nine-year-old boy who on December 22 2013 was tested with normal vision of 6/5 (U.S. 20/17 -- better than 20/20) but on December 26 complained of vision loss and was found to have 6/12 (20/40) in the left eye and 6/15 (20/50) in the right eye. The family said he was given a laser pointer as a “toy” and had been playing with it on Christmas Day. The child denied looking directly into the laser beam. The family had three laser pens: a 57 mW blue 405nm, a 42 mW green 532 nm, and a 72 mW red 650nm. All exceeded the British Standard of 5 mW for a Class 3R laser. The boy was prescribed steroids. Nine months after the initial complaint, the best corrected vision was 6/9.5 (20/32), and optical coherence tomography showed persistent outer retinal layer disruption at the fovea. [The boy was later identified in press coverage as William Jackson, from Wadsley. Details are at The Star.]
- Case 2 was of an 11-year-old boy. He had decreased vision in both eyes of 6/7.5 (20/25). Eight weeks later he had sub-foveal retinal pigment epithelium changes. His vision was 6/12 (20/40) in the right eye and 6/15 (20/50) in the left eye. He said that a friend had aimed a laser into both of his eyes before the decreased vision occurred. The doctors were not able to examine what they characterized as the laser “toy”.
- Case 3 was of a 15-year-old girl. She aimed a laser pen into both eyes for 30 seconds. The next day she had scotomas (vision loss or spots) in both eyes. Her right eye was 6/7.5 (20/25) and her left eye was 6/6 (20/20). Upon examination, a vitelliform-like maculopathy (abnormality in the macula or central vision area) was seen. She did not return for follow-up visits.
- Case 4 was of an 8-year-old boy who had reduced vision of 6/12 (20/40) in his right eye, and normal vision of 6/6 (20/20) in his left eye. The right fovea was seen to have retinal pigment epithelial changes “consistent with laser burns.” The boy admitted he had played with a laser pointer a few months before, but said he did not point it directly at his eye.
- Case 5 was of a 13-year-old boy who had noticed declining vision in his right eye. It was found to be 6/36 (20/120); his left eye was 6/6 (20/20). He admitted aiming a laser pointer into his right eye. A fibrosed choroidal neovascular membrane was found at the right fovea.
The authors noted that “The retinal damage reported following such injuries is variable. This is due to variety of laser powers and wavelengths as well as ocular factors such as fundal pigmentation, blink responses, pupil size, and proximity of the laser burn to the fovea. Assessment of alleged laser eye injury requires accurate history and examination. Treatment for such laser retinal injuries is uncertain. Oral corticosteroids are sometimes administered.”
The authors stated that some laser devices are marketed as “toys”. They said they are aware of other children in the U.K. with retinal injuries from imported laser pointers. They conclude: “We suggest that children should not be given laser pointers as toys.”

The case was reported in JAMA Ophthalmalogy under the title “Ocular Safety of Recreational Lasers.” Authors Glenn Yiu, Sujit Itty and Cynthia Toth are with the Department of Ophthalmology at Duke University Medical Center in Durham, North Carolina.
They described the boy’s injuries as being caused by a Spyder III Pro Arctic “a class 4, high-powered 1250 mW laser that is manufactured from the 445 nm blue diode of a dismantled home theater projector and that is commercially available for online purchase from overseas.” This brand of laser is manufactured by the company Wicked Lasers; an 800 mW version was reviewed here.
In the case they described, “the adult directed the laser at the child’s eyes in jest, unaware of the harmful consequences.”
A copy of the safety label that appears on a Wicked Laser Spyder III Pro Arctic, containing the IEC and U.S. FDA-mandated wording for a Class 4 laser: “Avoid eye or skin exposure to direct or scattered radiation”
According to the authors, “imaging studies suggest that the laser damage was limited to superficial retinal vessels with no involvement of the underlying retinal pigment epithelium or choroid. To our knowledge, this is the first report of a continuous wave laser in the visible spectrum–damaging retinal vessels without affecting the retinal pigment epithelium, the site where damage from visible lasers typically occurs.”
They speculate that this may be caused by greater absorption of shorter wavelength lasers by hemoglobin, or a defocusing of the laser due to chromatic aberration and myopia in a child.
The authors conclude that “with the expanding use of lasers in nonoccupational or recreational settings, escalation of laser safety awareness and consumer laser regulations is paramount to prevent future ocular laser injuries.”

The injury to her fovea is permanent. In a machine-translated statement, she said “All fuzzy horrors bothers me the light. I sense what I see on the screen, but I can not really read and, of course, I dare not drive.”
The clinic says this is the first case it has seen of permanent retinal damage by a laser pointer.
The woman’s husband purchased three lasers in a tourist area of Shanghai, for €30 (USD $40). One emitted a red beam, one a blue beam and one a green beam. The spower was said to be between 500 and 6,000 milliwatts (1/2 to 6 watts). There were no user warnings on the laser.
The clinic believes the laser was not aimed directly in the eye, but was probably reflected off an object. While the article and machine-translation are not clear, it is possible that one or more of the lasers used a diffraction grating to create multiple “stars”. The article discusses lasers that “allow decorative figures with the laser on the surface” and then quotes the victim as saying “Ours were beautiful: creating colorful stars in the sky.”

A December 2006 incident has come to our attention. A 15-year-old Japanese boy suffered a retinal injury and visual loss after deliberately looking into a 5 mW violet (410 nm) light emitting diode for a total of about 40 seconds. The LED was in a pen was sold as a toy called “Secret Pen”. The toy appears to consist of an LED light which can excite ink that is invisible under ordinary light but which fluoresces under ultraviolet and near-UV light. The 410 nm wavelength caused photochemical damage to the retina.
According to a 2011 paper in Retinal Cases & Brief Reports, the LED was aimed into the teen’s eye from a distance of about 1 cm. It was held there for about 20 seconds as he deliberately stared into the light. This exposure was repeated the next day. About two weeks later, decreased vision (20/50 on the Snellen scale) was noted in the right eye.

The laser pointer had no markings so the power is unknown. This also will be studied so the strength of the beam is known.
According to police, the laser pointer attack was a dangerous assault. If there is also significant permanent damage to eyesight, a charge of aggravated assault may be considered.

The 5-hour confrontation began the evening of March 17 2012. St. Patrick’s Day parties “spilled into the street” in an area near Fanshawe College. The crowd grew to about 1,000 people. A brush fire was started, and a CTV news truck was set on fire. To slow fire crews, some persons threw beer bottles, bricks, wooden planks, tires, rim and other debris. In addition, said London’s police chief, “members of the crowd used laser pointers aimed at our officers’ eyes to try to disrupt our response.” A spectator said that the crowd, made up primarily of students, “wanted to egg on the police.”

From the Toronto Sun. This is possibly the same laser beam; note glow from fire to the left, behind the officers.
The full extent of the laser misuse is not known. While the police chief indicated there were multiple lasers involved, the National Post said “One rioter attempted to blind the officers with a high-powered green laser.” Media reviewed by LaserPointerSafety.com found a single laser being used in each photo or video. Although some bystanders and police suffered minor injuries from thrown objects during the rioting, there were no reports of laser-caused eye effects or injuries. Eleven persons were arrested at the scene; charges included assaulting police. It is not known if any laser assault charges were brought.
In the video above, green laser light can be seen on a student, beginning at about 1:48. At 1:52, a single beam is shown being waved around at approximate head level. From 1:59 to 2:05, the beam is rapidly scanned towards stationary police officers who are monitoring the crowd. The beam in the video appears to come from the same person or area as shown in the photos above.
Similar riots occurred in the same area of Fleming Drive in 2007 and 2009, blamed on a high concentration of alcohol-fueled Fanshawe students. The 2012 riot is expected to cost London $100,000 in manpower and repair costs.

UPDATED, April 20 2012: Thirty-eight people are facing a total of 85 charges in the incident, thus far. Brian Nuccitelli, 18, faces three charges including two relating to misuse of a laser pointer: “possessing a weapon dangerous to public peace” and “assaulting a police officer with a weapon”. Police said the pointer was aimed at officers’ faces. They said “one officer was injured and continues to receive medical attention as the result of the laser being directed at his eyes.” In addition to Nuccitelli, police are also looking for another person who aimed a laser at officers.

In early February 2012, a male student was flashing a number of students with a laser pointer. Noelle-Marie Harrington, 16, was flashed in the eye. She went to an emergency room and to an ophthalmologist for evaluation. As of early March 2012, her vision is back to normal.
The boy was suspended for two days. However, the boy’s friends bullied Harrington. She had previously been bullied in middle school, as well as in high school. Harrington’s mother said the school was unable to stop the bullying, and in early March she withdrew her daughter from Attleboro High School.
