LASER POINTER SAFETY Laser Classes chart. Lasers are classified based on their potential for causing injury — especially eye damage, since the eye is most susceptible to excess laser light. There are four main classes for visible-beam lasers: Class 2, Class 3R, Class 3B and Class 4. The first two are relatively safe for eye exposure; the last two arehazardous.
LASER POINTER SAFETY A comprehensive resource for safe and responsible laser use Tips for bird dispersal with lasers There are at least two potential consumer uses for lasers outdoors, pointing out stars in the sky and dispersing birds. This page discusses tips for deterring and dispersing birds. LASER POINTER SAFETY Laser exposures can have a wide range of effects including flash blindness, dazzle, dark spots, hazy vision, floaters, burns, retinal bleeding, etc. Of special interest are the hazards posed by visible lasers from glare and flash blindness, and from very high energylasers that

LASER POINTER SAFETY A comprehensive resource for safe and responsible laser use Laser blinding weapons There are three primary uses of lasers as blinding (temporary or permanent) weapons. LASER POINTER SAFETY If the calculated irradiance above is greater than 2.54 mW/cm 2, then the laser light is a potential eye hazard. According to laser safety experts, the Maximum Permissible Exposure (MPE) for the eye to continuous wave visible laser light for a 1/4 second exposure is 2.54 mW/cm 2.This assumes that a person will blink, turn away or otherwise stop the exposure within 1/4 second. LASER POINTER SAFETY Background information. What are the NOHD and the ED50 distances? For pilots, an important concept is the Nominal Ocular Hazard Distance. Laser safety experts recommend not having direct eye exposure to a laser’s beam closer than the NOHD for that laser.

LASER POINTER SAFETY Laser Classes chart. Lasers are classified based on their potential for causing injury — especially eye damage, since the eye is most susceptible to excess laser light. There are four main classes for visible-beam lasers: Class 2, Class 3R, Class 3B and Class 4. The first two are relatively safe for eye exposure; the last two arehazardous.

LASER POINTER SAFETY Here are two better and more accurate ways to demonstrate LGP’s effectiveness. In these examples we will assume the laser pointer emits the same wavelength that the LGP is designed to attenuate. 1) Aim the laser pointer at a wall, away from people. Carefully insert one lens of the LGP glasses into the beam. LASER POINTER SAFETY Emergency signaling lasers. Generally, it is illegal in the United States to aim a laser beam at an aircraft. One of the few exceptions makes it legal to aim a “laser emergency signaling device to send an emergency distress signal” ( U.S.C. Title 18, Chapter 2, Sec. 39A (c) (3) ).

LASER POINTER SAFETY Don’t aim lasers at people. There are many danger factors. In general, the more powerful the laser, the closer a person is to the beam, and the longer the laser stays in the same area of the eye, the greater the possibility of eye damage. While eye injuries from lasers are rare, all laser beams should be treated as potentially dangerous. LASER POINTER SAFETY Here are some of the typical Amazon-sold laser pointers that they tested: Below are screenshots of the Amazon pages for the 405 nm laser outputting 87.6 mW, and for the 532 nm laser outputting 49 mW, of which 40 mW is dangerous invisible infrared light. Note that the lasers sell for $4.95 and $5.44, respectively. LASER RULES AND REGULATIONS FOR U.S. CONSUMERS All laser products (devices) must be certified by the manufacturer to comply with 21 CFR 1040.10 and 11.

------------------------- CAUTION FOR TRAVELERS TO SWITZERLAND WHO POSSESS LASER POINTERS _Even a presentation laser mouse like this could be confiscated from anyone in or entering Switzerland, if the laser is Class 2 or morepowerful._
If you are traveling to, or transiting through, Switzerland be aware that as of June 1 2019, laser pointers above Class 1 (0.39 milliwatts) are banned. SWISS AUTHORITIES WILL CONFISCATE AND NOT RETURN ANY LASER POINTER LABELED CLASS 2 (1 MW) OR HIGHER, AND ANY UNLABELED LASER POINTERS. This includes "hybrid devices" such as a PowerPoint presentation mouse that might include a Class 2 or higher laserpointer.
Many countries permit the sale, possession and use of Class 1 and Class 2 laser pointers. The United States also permits the use of Class 3R (IIIa) pointers of up to 5 milliwatts. However, all but Class 1 pointers are illegal in Switzerland from June 1. Swiss federal authorities have asked airports and information sources such as this website to help spread the word to travelers about the risk of having their Class 2+ laser pointers being confiscated iffound.

Switzerland to ban all laser pointers above Class 1 starting June 12019
Switzerland has banned selling, distributing, importing, or giving away laser pointers above Class 1 (0.39 milliwatts), as of June 12019.
Persons in Switzerland who currently possess laser pointers above Class 2 (1 milliwatt) must cease to use them beginning on June 1 2019, and must dispose of them before June 1 2020. Persons possessing Class 2 pointers can use them indoors only for presentations until June 1 2021, by which time they must be disposedof.
COMMENTARY FROM LASERPOINTERSAFETY.COM This is the most stringent restriction on laser pointers of any major country that we are aware of. Many countries permit the sale, possession and use of Class 1 (up to 0.39 mW) and Class 2 (up to 1 mW) laser pointers. The United States also permits the use of Class 3R (IIIa) pointers of up to 5 milliwatts. Switzerland is not permitting even the possession of laser pointers above Class 1, starting June 1 2020 (June 1 2021 for Class 2pointers).
And they will be confiscating any laser pointers (above Class 1) possessed by travelers into or transiting through Switzerland. _For more details on the June 1 2019 Swiss ban, click __here__.

Claim of WestJet pilot with eye injuries on Orlando flight A WestJet passenger plane about 25 miles from landing at Orlando International Airport was illuminated by a green laser on May 18 2019. According to the Federal Aviation Administration, the aircraft was descending through 10,000 feet at the time of the incident. FAA also reported that the pilot's eyes were burned. The pilot was referred for medical examination, as per WestJet's standard operating procedure. COMMENTARY FROM LASERPOINTERSAFETY.COM It is almost a certainty that the pilot's eyes were not burned by thelaser exposure.
Laser beams spread out with distance. At 10,000 feet a laser beam would expand to be at least three feet wide. Only a fraction of the beam power would go through the pupil of the pilot's eye. (In fact, of the original laser irradiance, only 0.003 percent would go through thepilot's pupil.)
A laser beam that traveled 10,000 feet would have to be 32 to 320 times stronger than the most powerful claimed handheld laser, to even potentially cause an eye injury. _For more details on this incident, and why there is no practical chance of an actual eye injury, see the story __here__._

Using liquid crystals to scatter laser light on aircraft windscreens Researchers at Lewis University, near Chicago, are investigating the use of liquid crystals embedded between glass to block up to 95 percent of laser light. The goal is to have a windscreen that will turn opaque only where laser light is illuminating the glass; the remainder of the windscreen will remain transparent. The research was presented by Jason Keleher, Ph.D. on March 31 2019 at an American Chemical Society meeting in Orlando, Florida. Details are at this LaserPointerSafety.com news article.

U.K. study finds 200+ laser pointer eye injuries; highlights hazards especially for children A paper published online in March 2019 by the journal "Eye" found that children with behavioral, learning or mental health problems are at special risk from misuse of laser pointers. Such children may not understand the eye injury hazard, and may not be able to follow label or parental instructions for keeping the laser pen from their eyes. The study found around 240 laser eye injury cases 1) in the literature, 2) from a survey of ophthalmologists, and 3) from their own clinical practice. Most of these involved children. For details, including four detailed case studies and the implication of these findings for making policy, see our story here.

U.S. pilots report about the same number of laser incidents in 2019 thus far, compared with 2018 Below are recent changes in laser incidents reported to the U.S. Federal Aviation Administration (FAA). FIRST 22 WEEKS OF 2019 ROUGHLY EQUAL TO SAME PERIOD IN 2018 According to FAA, from January 1 2019 to June 1 2019 there were 2,356 reports submitted by pilots of seeing or being illuminated by laser light during flight. This is a 0.6% increase over the 2,343 reports during the same time period in 2018. 14% DECLINE IN ALL OF 2018 COMPARED TO 2017 During all of 2018, pilots reported 5,663 laser illumination incidents to FAA. This is a decrease of 16.1% compared with the 6,754 incidents reported during 2017. 23.5% DECLINE FROM PEAK IN 2015 The 2018 annual total of 5,663 laser incidents is a decrease of 23.5% compared with the highest U.S. year, 2016, which had 7,398 reported laser illuminations of pilots. At least some of the decreases may be due to pilots not reporting laser incidents as often. There are anecdotal indications that some pilots have grown frustrated with reporting laser illuminations, without a significant drop in the incident numbers, so they no longer report less serious incidents. Therefore, it is not possible to accurately estimate how much of the reduction is a true drop in the number of people aiming at aircraft, and how much is a drop in pilot reporting rates.

Canadian study is first to show prevalence of laser use, injuries among general public A 2014 health survey by Statistics Canada, reported in January 2019, is the first study to show the prevalence of laser usage and of laser injuries among a large sample of the general public in any country or region. 19,765 individuals were surveyed in the study. It showed that 48 percent of Canadians over the age of 12 either used or were exposed to lasers, annually. This would be roughly 14 millionpeople
Of those who reported using a laser product, 1.1% reported discomfort or injury; this would be around 155,000 Canadians. The study went on to provide details about what caused the discomfortor injury.
The study also looked at published eye injury case reports since 1999, and concluded "the majority involved the misuse of a handheld battery-operated laser product by an adult or a child. Most of these injuries were the result of irresponsible use or deliberate staring at a laser by a child, or the result of the inappropriate use of a high-powered laser device (Class 3B or 4) in an 'uncontrolledenvironment'."

------------------------- LEARN FROM HIS MISTAKE — DON’T AIM LASERS AT AIRCRAFT A California man wrote a letter apologizing for aiming a laser at a sheriff’s helicopter. He describes how it ruined his life: I was convicted of one count of aiming a laser pointer at an aircraft and sentenced to 24 months in a federal penitentiary, then 36 more months of supervised release for a total of 60 months — five years — plus ordered to pay a special assessment fee of $10,000. I am very lucky the pilot was an expert and highly skilled at pilotingthe helicopter.
I also want to educate anyone who owns a laser and might be inclined to use it the way I did: Learn from my mistake. I am now just getting out of prison. I have paid dearly, for I have lost my girlfriend, my dog, my home, my vehicle. Everything I owned, everything I have worked for 30 years of my life, is gone. For shining a laser at a helicopter for three seconds, I lost my entire life. I am now 54 years old and I have no one and nothing but the clothes I was given when I was released from prison.

Eye hazard results:
NOHD: 51.86 feet (eye safe beyond this distance) ( 32.8 / ) * ( sqrt ( 0.5 * ) ) Beyond the Nominal Ocular Hazard Distance, laser light directly entering the eye is considered safe. Specifically, at the NOHD distance there is “a negligible probability of damage” according to the laser safety standard ANSI Z136.1.
The light level (irradiance) at the NOHD is at the Maximum Permissible Exposure or MPE. Farther than the NOHD, the irradiance falls below the MPE, and is generally considered safe. ED50: 16.41 feet (50-50 chance of small injury) ( ( 32.8 / ) * ( sqrt ( 0.5 * ) ) / 3.16 )At the ED
50
distance, there is roughly a 50-50 chance that a fixed laser beam aimed into an unmoving eye under laboratory conditions will cause the smallest medically detectable change to the retina. Such small changes can heal just as small skin cuts and burns can heal with no adverseeffect.
The ED50 distance is about 1/3 of the NOHD. The extra space between the ED50 distance and the NOHD gives an added “safety margin” or “reduction factor.” Beyond the NOHD, the laser light is considered unlikely to cause any eye injury. BEING EXPOSED TO LASER LIGHT WITHIN THE NOHD DOES NOT MEAN THAT A PERSON WILL AUTOMATICALLY RECEIVE AN EYE INJURY, OR EVEN IS LIKELY TO HAVE AN INJURY. The NOHD is a “nominal” hazard distance, not an actual hazard distance. The closer the person is to the laser, the greater the chance of an injury, as indicated by the colors above.

------------------------- UNDERSTAND WHY LASER BEAMS ARE LESS HAZARDOUS AT GREATER DISTANCES While laser beams may look thin, they do get wider — and thus less hazardous — with distance: Take for example a laser pointer with a tight 1 milliradian beam. The beam is a millimeter or two in diameter at the exit aperture. At 50 feet (15 m) it has spread to over 1/2 inch (15 mm) in diameter. At 500 feet (150 m) — the height of a hovering helicopter — it has spread to 6 inches (150 mm) across. A human pupil is about 0.16-0.28 inches (4-7 mm) across, depending on lighting conditions. If a beam is, say, 6 inches across, then clearly most of the beam power does _not_ go through the pupil: THAT’S WHY A LASER BEAM THAT CAN POP BALLOONS OR LIGHT CIGARETTES UP CLOSE, COULD BE EYE-SAFE HUNDREDS OF FEET AWAY.__
Now, an eye-safe beam may still be very bright. It could cause temporary flashblindness, or vision-blocking glare, or be a distraction. This would be a hazard to persons such as pilots during critical phases of flight. The second part of the calculator above lists the distances for those visual interference hazards.*
Some sample eye hazard distances If a laser pointer had an output power of 5 milliwatts and a beam divergence of 1 milliradian, the beam would be considered eye safe for momentary exposure (blink or turn away within 1/4 second) after about 50 feet. At 500 feet, even deliberate staring into the beam would notcause an injury.
For a stronger beam such as 499 milliwatts — the highest power Class 3B laser — the beam would be considered eye safe for momentary exposure after about 520 feet. The “eye safe” distance is called the Nominal Ocular HazardDistance, or NOHD.
The NOHD has a built-in safety or reduction factor. As the color-coded diagram below indicates, a laser beam is most hazardous at close range (red), and gradually becomes less hazardous until at the NOHD the chance of an injury is considered “vanishingly small.”_
_
_
_The ED50 distance is about 1/3 of the NOHD. At the ED50 distance, there is a 50/50 chance of the laser causing the smallest medically noticeable retinal lesion under laboratory conditions where both the laser and the eye are stationary. Often such a lesion will heal, in the same way that a minor skin burn can heal. Beyond the ED50 distance, the chance of having a retinal lesion is further reduced. For a 5 mW 1 mrad laser, the ED50 distance is 16 feet. For a 499 mW 1 mrad laser, the ED50 distance is about 164 feet. This helps explain why a laser that is nominally hazardous at a certain distance (the NOHD) is extremely unlikely to cause even a small injury at that distance. There is more information about the NOHD and the ED50 distance on thispage .

Technical details about the pupil-beam comparison The illustration above compares a 7 mm dark-adapted pupil to a 150 mm diameter laser beam. The title states that “Less than 1% of this laser beam’s power goes into the pupil of an eye 500 feet away”. As with so many aspects of laser hazards, there are important detailsto consider.
The beam is brighter in the center The area of a 7 mm diameter circle compared with a 150 mm diameter circle is 38.5 mm2 divided by 17,671 mm2, or 0.0022 which is also 0.22%. Said another way, a 7 mm circle’s area represents only 0.22% of a 150 mm circle’s area. However, the center of a typical laser beam is brighter than the edges. If a person’s pupil was in the center as illustrated, it would receive more than 0.22% of the light. The exact exposure would depend on what part of the laser beam went in the eye. To be conservative, we simply state that a 7 mm pupil would receive “less than 1% of the laser’s light”. A smaller pupil is safer Another aspect in many or perhaps most laser exposure incidents is that the pupil may be smaller than 7 mm, meaning it lets in less laserlight.
A completely dark-adapted pupil is generally 7-8 mm in diameter. But for a pilot in an aircraft, their pupil is NOT dark-adapted. There are instrument displays and lights in the cockpit, and city lights (when landing) outside the cockpit. Let’s say the pupil is more constricted, at 5 mm. This has an area of 19.6 mm2, which is half of the 38.5 mm2 area of a 7 mm pupil. This increases safety — only half the amount of laser light can get through the pupil and onto the retina, compared to a completelydark-adapted eye.
A moving beam is less hazardous Yet another aspect that increases safety is that the laser light is moving, relative to the pupil. If the laser light is always focused on the same area of the retina, this allows heat to build up. But in many situations where a person is trying to avoid a laser light being hand-aimed at them, the light is moving relative to the eye. * This movement may be because of the inherent difficulty of keeping a laser beam on target over hundreds of feet. (You can see this invideos of lasers
being aimed at helicopters, where the beam only occasionally hits the camera lens. Each frame below is 1/30 of a second; only one of the frames is a direct hit on the lens.) * This movement may also be due to the illuminated person moving their head and eyes to avoid directly staring into the beam. In both cases, the laser light does not have as much time to stay on one spot on the retina. This reduces the chance of causing a lesion orburn.
Of course, if a laser is powerful enough and a person is close enough — say, within the NOHD and certainly within the ED50 distance — a brief 1/4 second exposure can cause a retinal lesion. But for laser illuminations of pilots at aircraft distances of many hundreds or thousands of feet, even powerful lasers are considered by experts to be unlikely to cause serious or permanent harm.
------------------------- A SPECIAL MESSAGE FOR LASER POINTER USERS There are far too many incidents where airplanes, helicopters, vehicles, athletes and ordinary citizens are harassed by laser pointer beams. It is ANNOYING, at best.
It can be UNSAFE
if the beam gets in someone’s eye or if it causes a driver or pilot to be distracted or flashblinded. You personally can get ARRESTEDand even
JAILED .
Plus, laser incidents create a BAD IMAGE and can lead to laser pointers being BANNED.
This has happened in a number of areas. (In New South Wales, you can be fined for possessing a laser pointer, and you can go to jail for up to 14 years for a laser assault.) There are strong calls in Canada, the U.S., and the U.K. to restrict or ban lasers. It is really simple: NEVER AIM A LASER BEAM AT AN AIRCRAFT, A VEHICLE, OR TOWARDS STRANGERS. IN OTHER WORDS, DON’T ANNOY PEOPLE WITH THELASER BEAM.
