A comprehensive resource for safe and responsible laser use

A California Highway Patrol (CHP) officer noted multiple hazards, from eye injury to blinding vehicle operators: “So, if a laser got in the eyes of a sideshow participant, it is going to cause temporary blindness, permanent eye damage. It could cause the driver to lose control of the vehicle itself. If he loses control, it is going to hit multiple people at once and cause mass injuries…. The lasers could cause temporary blindness for the pilot, could cause the pilot to alter their course, and it could cause the helicopter to crash.”
During the same time period in December 2017, there was also a report of multiple laser strikes on airplanes landing at Oakland International Airport (story here).

According to a news story, “the boy sustained damage to his eyes and required hospital treatment.” A police spokesperson called the injuries “serious.”

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.
A report will be sent to the Youth Justice Assessor.
The managing director of one of the busses involved said “…to shine a laser into the eyes of someone who is driving a bus is unbelievably reckless. The lives of our drivers, passengers and other road users are potentially put at risk during this sort of incident, as the person behind the wheel is temporarily blinded.”

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.”

The October 6 2017 incident began when Roberto Callejas, 35, told his family he was waiting for the officers to arrive, and that he had a bomb. While it was later found that Callejas did not have any explosives, he did have two knives and a laser pointer.
When police arrived with a warrant for armed trespassing, Callejas put a knife to his throat. Police tased him. He fell to the ground, then came back up and aimed what police thought was a laser gun sight at them. Officers shot him. Callejas fell again, and again came back up; this time he tried to throw a knife at the police. Officers shot once more and killed him.
According to an Orlando Police spokesperson, Callejas had threatened police before. Police Chief John Mina said “To me it seems he wanted to die at the hands of police.”
Note: This comes on the heels of a similar September 2017 incident where a 31-year-old Bronx man refused to put down a knife and a toy gun with an integral laser pointer. The man was shot and killed after he aimed the toy gun/laser pointer at officers, according to the police account.

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.

Analysis from LaserPointerSafety.com: There is a Joplin city ordinance, dating from 1999, that makes it illegal to annoy, harass or injure a person or animal. It also is illegal for a person under 18 to possess a laser pointer. It is not known how it would be illegal for a 36-year-old to possess a laser pointer.

Police released four videos from officers’ body-worn cameras, showing how the incident progressed. A detailed look at the laser light seen in videos is below. First though, a summary of the incident.
The fatal incident
Police had been called by Richards’ landlord because Richards had not been seen for a few days. Confronted by two police officers in his Bronx apartment bedroom, Richards stood motionless and silent throughout most of the incident. He had a knife in one hand and the toy gun behind his back.
Body-worn video shows the scene.
Police asked him dozens of times to drop the knife and put his hands up. After about 10 minutes, they noticed the gun.
An officer told Richards “"Drop that gun, dude. Drop that gun. I don't want to shoot you if you've got a fake gun in your hand. You hear me? But I will shoot you if that's a real gun."
Two additional officers then arrived; one pulled out a stun gun. Richards appeared to raise his arm and aim the laser pointer towards the officers. The officer with the stun gun fired. After a few seconds, and a possible second laser “shot” from Richards, a second officer fired nine bullets, a third officer fired seven bullets, and the fourth officer did not fire.
Richards died at the scene.

She was treated at a hospital for “extreme burning pain.” She recovered with no lasting damage.
The laser attack happened in Carlisle, Cumbria around September 13 2017. It was not clear from news reports whether the ambulance driver was delayed in reaching the patient, or whether another ambulance was sent.

Passers-by saw the youths — described as a “gang” in a news report — and reported them to a passing member of the Bedworth Safer Neighborhood Team. An officer from the team said SNT is investigating the “potentially very dangerous” pranks. The officer also said “I would ask parents if these were their children to have a serious word with them.”

A caller had reported to police that a man had “something attached to a laser that appeared to be a firearm.” Police arrested Jose M. Padilla as he was leaving the area in a van.
Padilla had been arrested July 10 2017 on a firearms charge. He was not to possess firearms or ammunition. When arrested on July 18, ammunition was found in the van.
He was charged with two misdemeanors: suspicion of violating a firearms emergency protective order, and suspicion of pointing a laser pointer with the intent to cause a person to fear harm.

The following is from a Coast Guard press release dated May 4 2017:
The Coast Guard is investigating multiple laser strikes during the past month aimed at commercial vessels transiting the Chesapeake Bay and warns the public of this dangerous act.
Four incidences occurred early Wednesday morning between midnight and 3 a.m., involving the motor vessels Salome, Bulk Spain, and AM Annaba. Additionally, a pilot vessel was lased as it was on its way back to the pilot launch.
Three other incidents occurred: Monday around 2 a.m., involving the motor vessel Hoegh Osaka; Sunday at 4 a.m., and involved the cruise ship Carnival Pride and another April 7 at approximately 1 a.m., involving the motor vessel Maersk Kolkata.
During all incidents, the laser light was described as steady, powerful and somewhat painful to the eyes. The reporting source believes the laser originated in the area between Drum Point and Cove Point, and lasted for approximately 15 minutes.
“Laser lights, and other bright lights can be a hazard to navigation,” said Lt. Trish Elliston, Coast Guard Sector Maryland-National Capitol Region. “The most likely scenario is the laser would blind or distract a pilot which would prevent the pilot from seeing a smaller vessel. This could cause a collision or other serious incident in the shipping channel.”
The Laser Safety Act, makes it a misdemeanor to knowingly and willfully cause or attempt to cause bodily injury by shining, pointing, or focusing the beam of a laser pointer on an individual operating a motor vehicle, vessel, or aircraft. The penalty is a maximum 10 years in prison and a fine of up to $2,500.
The Coast Guard is working with state and local law enforcement along with Chesapeake Bay Pilots to investigate the incidents. Anyone with information leading to the whereabouts of the individual, or individuals, involved are asked to contact the Coast Guard Sector Maryland-National Capital Region Command Center at 410-576-2525 or via email at firstname.lastname@example.org.

Police said that the victim “is likely to have to undergo surgery to repair damage caused to his back following this incident.”
The attack happened at about 9:20 pm on April 23 2017. Police did not release details until May 4.

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.

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.
