A comprehensive resource for safe and responsible laser use

Risks of lasers compared with other products and activities

Lasers are still so new, and injuries so relatively rare, that people may not have an accurate perspective about lasers’ relative risk. Below is some information on deaths and injuries due to lasers, as well as due to other devices and activities. (All statistics are for the United States unless otherwise noted.)

Publisher’s comment: The information on this page has been somewhat controversial. Some safety experts feel that it is unrealistic or even unsafe to compare laser risks with other devices and activities. They feel each risk should be managed on its own.

Other persons such as myself, want to at least provide factual data as a starting point for comparison. There are two main reasons:

Laser safety does not exist in a vacuum. Funds for safety are limited. An agency such as FDA and those overseeing them -- Congress and ultimately the American people -- must decide how much effort to put into lasers versus other public health hazards. Looking at relative injury rates, and injury severity, can provide some guidance as to how best to allocate scarce funds.

Every product and every activity in our society carries some risk. Whether it is automobile driving, household knives, roller coasters, fireworks or laser pointers — unfortunately there will always be some accidents and some deliberate misuse. This is because 100% safety is impossible. Comparing laser incident numbers with those from other devices and activities can give the public a better perspective as to lasers’ relative risks in society.


Industrial and military lasers

Injuries: An August 2004 article in the Archives of Ophthalmology states “It is estimated that fewer than 15 retinal injuries worldwide each year are caused by industrial and military lasers.” The article gives footnoted references for the statement, which appears on page 1211. Similarly, a July 2012 paper in PLoS ONE states that “a review of military and civilian data sources in 1997 estimated that 220 confirmed laser eye injuries have occurred between 1964 and 1996; ”this is an average of 6.9 injuries per year.”

A laser safety expert told LaserPointerSafety.com “I think this number has increased significantly since Iraq and Afghanistan,” apparently due to injuries suffered by military personnel in a war zone. It is not known how many were caused within a military’s own laser usage (accidents) and how many were caused by enemy forces (deliberate actions by hostile persons).

Incidents and accidents: There is no central database for all laser-related incidents. See the LaserIncidents.com website for a list of databases that compile incident and accident reports.

Laser pointers and handheld lasers used by the general public

Deaths: None

Injuries from momentary (accidental/unwanted) exposures: According to the U.S. Food and Drug Administration (FDA), as of April 2012 the FDA has never received a report of eye injury from momentary exposures to laser pointers of Class 2 and 3R power (e.g., below 5 milliwatts).

Injuries from deliberately-caused exposures: Many proven or credible reports of laser eye injuries to the general public are self-inflicted -- often by youths who do not realize (or care about) the consequences. FDA has heard of injuries caused when a person intentionally stared into the beam for a prolonged period of time.

Injuries from consumer lasers: See the page with Consumer laser eye injury info

Data from New Zealand’s national insurance system show that over the period 2000 to 2013, there was an average of 8.9 claims for laser eye or skin injuries each year. The average claim amount was NZD $93.63 (USD $61.42), which a representative said “would suggest the injuries were not significant.” The data includes all New Zealand laser injury claims, whether verified or not, from all sources including lasers used in industry and laboratories. Detailed statistics and analysis are in
this article.

Injury severity: If there is an injury, most often these are small spots in the periphery of vision. Often these heal or the brain “fills in” the spot so the person normally does not notice it. There have been some cases of near-total or total blindness caused by laser pointers or handheld lasers; usually these are self-inflicted. The Consumer laser eye injury info page has links to studies of some of these cases.

Other pointer and handheld laser concerns
  • Low potential for eye injuries to pilots - Permanent retinal damage from lasers aimed at aircraft is not a major concern of laser and aviation experts. While a laser-caused eye injury is theoretically possible, experts consider this highly unlikely thanks to various factors including relatively low laser powers and the relative motions of the handheld laser, aircraft, pilot’s head and pilot’s eyes. Helicopter pilots flying “low and slow” would be at greatest risk from any possible eye injury.
  • Distraction/flashblinding of pilots - This is a significant concern for aviation. FAA incident reports rose from 384 in 2006 to a peak of 7,703 in 2015.
  • Distraction/flashblinding of automobiles - This does not seem to be a significant problem. Motorist incidents are reported from time to time; one expert said he hears of “several media reports per year”. We are aware of one confirmed incident where a laser pointer aimed at a driver caused a three-car accident with body damage but no injury. We have not found any other reports of deaths, injuries or property damage attributed to laser pointer misuse against motorists (compare to roughly 65,000,000 automobile accidents in the U.S., in the past 10 years). Some persons have said that perhaps there have been fatal accidents caused by aiming a laser at a car (thus there would be no one alive to report the cause). However, the fact that we cannot find reports of less-than-fatal accidents causing injuries or property damage makes this unlikely.
  • Misuse at concerts and sporting events - Distraction or disruption of the event is the major concern. Eye damage is unlikely to occur due to various factors including the illuminated person moving and closing their eyes. There are perhaps 1-2 news accounts of “laser louts” each month. Anecdotally, these incidents seem to be more prevalent outside the U.S. and often are soccer (football) related.
  • Misuse and annoyance of the general public - This does not seem to be a problem, except in a few resort towns during the summer season where laser pointers are widely sold. (See these stories about Ocean City NJ and Ocean City MD.) For example, Ocean City MD reported that sales of 30,000 laser pointers in the first half of 2010 led to “Star Wars” on the boardwalk. Some resort towns such as Myrtle Beach SC have restricted sales and/or possession of laser pointers due to annoyance, and concerns over more serious misuse such as injury potential and aircraft dazzling.

Laser light shows

Deaths: None

Injuries: About 5 worldwide in over 30 years. Since laser shows began in the mid-1970s, an estimated 110,000,000 persons have been exposed to 11,000,000,000 pulses of continuous-wave laser light in their eyes. These 11 billion exposures resulted in about 5 proven or suspected injuries, worldwide, in 30+ years of laser shows.

Distraction/flashblinding of pilots: None. Specifically, the International Laser Display Association is not aware of any incidents linked to FDA-reviewed (“varianced”) outdoor laser shows since about the year 2000. While it is possible that illegally produced shows have illuminated pilots, ILDA is not aware of any of these incidents either in the past decade. (From about 1994 to 2000, outdoor laser light shows were a concern because the effect on pilot vision was not well understood. ILDA worked with SAE G10T to help develop FAA’s current guidelines and regulations.) For more information on the safety of outdoor shows, see the ILDA page.

Source for injury statistics: “Scanning Audiences at Laser Shows”, which gathered injury reports from a private study, from Internet searches, and from the Rockwell Laser Industries incident database.

Note: The above statistics on laser light shows are for continuous-wave (CW) laser light, which is the only type that should be used for audience-scanning shows. There have been three incidents where pulsed lasers were erroneously used and a total of 50 injuries occurred. Because pulsed lasers should NEVER be used for audience-scanning, only CW lasers are considered for laser light show injury statistics.

Aircraft shoot-downs & deaths

Portable missiles (MANPADS)

The sometimes deliberate use of lasers against aircraft brings to mind another technology which has also been used against aircraft: shoulder-launched surface-to-air missiles. These are also called man-portable air-defense systems, or MANPADS.

Deaths & attacks: “As many as 500 fatalities” from an estimated 35 MANPADS attacks on civil and commercial aircraft, since 2006. Wikipedia has a list of notable uses of MANPADS against civil aircraft.

Bird and animal strikes on aircraft

2012 data

In 2012, there were 10,726 strikes of animals (10,343 were birds) on aircraft, that were reported to the FAA. 606 of these strikes caused damage to the aircraft. There was a negative effect on the flight for 7% of the bird strikes; usually this was in the form of a precautionary emergency landing (4%) or an aborted takeoff (2%).

Cessna Citation C560 bird strike
A Cessna Citation C560 hit a turkey vulture at 1,500 feet altitude AGL.
It took 2 months and $200,000 to fix the damage.

Compare this to the worst year for FAA-reported laser illuminations, 2015, which had 7,703 incidents of aircraft being illuminated by laser light. None of these "strikes" caused damage to aircraft. Fifty-three of these reported incidents (0.7%) caused a temporary adverse visual effect such as flashblindness, afterimage, blurry vision, eye irritation and/or headache.

1990-2012 data

Over the 23-year period 1990-2012, there were 131,096 strikes of animals (127,212 were birds). During the same 23-year period, there were roughly 14,200 laser “strikes” reported to the FAA. 12,892 of the animal strikes caused damage to the aircraft; 60 aircraft were destroyed or damaged beyond repair.

In the U.S. from 1990 to 2012, ten wildlife strikes resulted in 24 human fatalities. Globally, wildlife strikes have killed more than 250 people and destroyed over 229 aircraft since 1988 including the 19-fatality crash of a Dornier 228-200 in Nepal in September 2012 after a vulture was struck on take-off.

General injuries

General injury statistics

Deaths: 160,000 Americans died from injuries in 2002. Injuries are the leading cause of death for people aged 1 to 44.

Injuries: 28,000,000 Americans suffered non-fatal injuries in 2002.

Eye injury statistics

For the period 2002-2011, there were over 47,000 patients diagnosed with eye injuries resulting in hospitalization in the U.S. The leading cause of eye injuries was falls, with 8,425 over the ten-year period. Fighting was the second leading cause, with nearly 8,000 hospitalizations for eye injuries. The median cost of treating these injuries rose from $12,430 in 2002 to $20,116 in 2011.

Household & consumer items

Knives and cutting instruments

Deliberately-caused deaths:
1,825 people were murdered with knives or cutting instruments in 2009, according to the FBI. (This is deaths caused by one person to another. We were unable to find statistics on additional deaths that were accidents or self-inflicted.)

Deliberately-caused injuries: In the U.S. in 2007, there were 76,000 visits to emergency rooms due to intentionally-caused injuries from "cutting or piercing instruments," according to CDC National Health Statistics (table 13). In Britain in 2008, there were 13,795 "victims of knife wounds ... admitted to accident and emergency departments", according to the Department of Health.

Accidental injuries: In the U.S. in 2007, there were 2,089,000 emergency room visits due to accidental injuries from "cutting or piercing instruments or objects", according to the same CDC table referenced above.

“Knife Rights”: A U.S. organization called Knife Rights “oppose[s] efforts to restrict the right to own, use and carry knives and edged tools.” For example, in July 2017 they supported a Texas law allowing open carry of knives with blades longer than 5.5 inches, including swords, spears, daggers, sabers, bowie knives and machetes. The law passed and takes effect September 1 2017. Knife Rights was formed in response to a July 25 2006 Wall Street Journal article, “How New, Deadly Pocketknives Became a $1 Billion Business.”

Other concerns
  • Assaults - The U.S. in 2008 had 138,720 aggravated assaults using "knives and cutting instruments", according to FBI statistics. In Britain in 2008, there was a similar number -- almost 130,000 assaults with knives, according to the British Crime Survey.

Commentary from LaserPointerSafety.com: Handheld lasers are sometimes compared with knives and blades. Both objects have legitimate uses, and yet both can be misused to cause accidental injuries and deliberate attacks. There are various types and sizes of knives, just as there are different powers and colors of lasers. Some types of blades (switchblades, sharp swords) may be banned or regulated as being too dangerous, just as there have been calls to ban or regulate some types of lasers. Obviously there are differences as well. Lasers can annoy or harm at a distance, while knives are close-in weapons. On the other hand, handheld lasers cannot severely injure (except eyes, in rare instances, and we are unaware of any deliberate attacks that ended in blindness), and handheld lasers cannot kill a person.


Deaths and injuries: Six Americans died and 8,700 were injured by fireworks in 2012, according to the U.S. Consumer Product Safety Commission. About half of injuries involve burns to the hands, head and face. About 20% were due to sparklers and bottle rockets, which are “often considered safe for small children” even though sparklers burn at 2,000 deg. F which is as hot as a blowtorch.

Nerf gun eye injuries

Injuries: A hospital’s emergency room reported three cases of bloody eye injuries, all within a 3-month period, caused by a Nerf gun “bullet” being fired into an eye. An 11-year-old had swelling that could lead to vision loss. Two adults were treated with medicated eye drops and recovered. In all cases there was more than 1 mm of traumatic hyphema (pooling of blood in anterior chamber of the eye), indicating significant ocular trauma.

The doctors noted that “Significant Nerf gun ocular injuries are not reported in the literature, as far as we know.” They recommended that those using or in the path of Nerf guns wear protective goggles.

An additional case is described in a comment to a story published at AboutLawsuits.com. The commenter said he was shot in the eye by his son from 20 feet away, “causing temporary total blindness and lots of pain.” This was with a Nerf Firestrike Elite gun using Nerf Elite bullets.

Holiday decorating, including Christmas lights

Injuries: During November and December 2010, there were more than 13,000 U.S. emergency department visits due to injuries related to holiday decorating. Most injuries were due to falls while putting up Christmas lights. In one case, a man slipped and got his neck tangled in the lights. He was rescued by a neighbor before strangling but the incident left a ligature mark across his throat.

Injuries: From 1990 to 2009, there were more than 65,000 U.S. emergency department visits by children under 18 for battery-related issues. As of 2012, over 3,250 American children are admitted to emergency rooms each year for swallowing batteries, primarily button types. That is one visit every three hours. The numbers are on the rise, according to a 2012 report in Pediatrics. Microcurrent from body moisture can burn a hole through the esophagus within two hours.

Deaths: Nine children died from 2004 to 2009 in the U.S. from complications due to ingesting button batteries.


Deaths: Each year in the U.S., an average of 4.5 children die after falling out of windows.

Accidental injuries: Each year in the U.S., more than 5,000 children are taken to the hospital due to injuries from falling out of windows. Of those, about 25% or 1,250 are admitted to the hospital due to the injuries being serious. The rate is about 7.3 window-related injuries per 100,000 children.

Injuries: In the decade from 1999 to 2008, 932,000 children under the age of 5 were hurt in stair accidents in the U.S., according to a study in the journal Pediatrics. The rate is 465 stair-related injuries per 100,000 children. The study blamed “preventable factors” such as stairway design, consumer awareness and parental education.

Deaths: Between 2000 and 2011, 215 U.S. children died from injuries caused by a falling TV -- one every three weeks. This happens when the TV tips over and crushes the child.

Injuries: Between 1990 and 2011, 380,885 children were treated in U.S. emergency departments due to falling TVs. This is one every half-hour. The average annual injury rate is 2.43 TV-tipover injuries per 10,000 children. The number and rate of injuries has increased significantly, as flat screens have become more common. The study’s senior author said “This is a call to action. These are 100 percent preventable injuries.”

Additional consumer hazards

The website ConsumerDangers.com is “a comprehensive free resource for the public to learn more about every day products that can potentially cause harm.”

As of April 2017 they have information about the following consumer products: Baby Slings, Bassinets, Defective Dressers, Drop-side Cribs, High Chairs, Magnets, Metal Children’s Jewelry, Strollers, Tube Televisions, Trampolines and Window Blinds. They also have information about medical dangers and consumer safety devices and drugs.

Recreational activities

Amusement park rides

Deaths: On average, there were 4 to 5 deaths per year in the mid-2000’s from amusement rides at both fixed sites (theme parks) and mobile sites (fairs). This figure does not include inflatable slides and bounces. From 2010 to mid-2017, there were 22 deaths caused by amusement park thrill rides, according to the U.S. Consumer Product Safety Commission (CPSC)

Injuries: The CPSC estimated that in 2016, 30,800 injuries severe enough for emergency room treatment were caused by amusement park attractions.

The Outdoor Amusement Business Association claims that 60 percent of ride injuries are caused by guests behaving inappropriately.

Figures from an industry association:
According to the 2011 Fixed-Site Amusement Ride Injury Survey, approximately 297 million guests visit the 400 U.S. amusement parks annually and take 1.7 billion safe rides. The chance of being seriously injured on a ride at a fixed-site park in the U.S. is 1 in 24 million. 61 out of the 1,415 ride-related injuries, or less than 5 percent, required overnight treatment at a hospital.

Wikipedia has a page on “Amusement park accidents” which lists some statistics, and also has links to other Wikipedia pages about incidents at various amusement parks.

Bounce houses and slides (inflatable amusement rides)

Deaths: As of mid-2010, there have been at least three recent reported deaths: a Pennsylvania man in June 2010, a 5-year-old boy killed in Kansas in March 2010, and a 5-year-old girl drowned in Florida in January 2010.

Injuries: In 2004 there were 4,900 injuries (up from 1,300 in 1997) according to the Consumer Product Safety Commission. MSNBC reported: “At least 10 inflatables around the country have been toppled by winds or collapsed under too much weight in the last two months [April - June 2011], injuring more than 40 people, according to www.rideaccidents.com, a website that tracks amusement ride accidents.”

Comment from the Association of Amusement Ride Safety Officials: “I wish this was a rarity, but it's not. It happens all the time. These are probably the most dangerous amusement devices they have.”

Participant sports and recreation

Injuries: There are approximately 3,700,000 emergency room visits annually for injuries related to participating in sports and recreation, according to a 2005 study by the Centers for Disease Control (see sentence 1 under Priority C).

Societal costs of alcohol, cigarettes, and lack of exercise

Alcohol: Binge and heavy drinking cost U.S. society at least $224 billion in 2006, according to a 2011 study by the Centers for Disease Control and Prevention. The study looked at medical expenses, property damage from car crashes, lost productivity, and incarceration costs. Binge drinking was defined as four or more alcoholic beverages on one occasion. According the CDC, this works out to $1.90 per drink in costs to society.

Cigarettes: The U.S. societal cost of smoking is estimated at $193 billion per year.

Lack of exercise: The U.S. societal cost of lack of exercise is estimated at $150 billion per year.

Governmental activities

Police pursuits

From 2002 to 2012, police pursuits in one state, California, killed 321 persons and injured more than 10,000 people. A state law was passed in 2006 trying to reduce this collateral damage; however, the incidents have increased since that time. Currently, there is one death for every 132 California chases.

An advocacy group says that across the entire U.S., pursuit-related crashes kill over 250 people per year.
