A comprehensive resource for safe and responsible laser use
The paper examined the red laser's output and found it was 1.7 milliwatts. This is four times the Class 1 limit of <0.39 mW, and is 1.7 times the Class 2 limit of <1 mW. The laser should have been classified as Class 3R (<5 mW limit).
The author notes that according to the European standard EN 62115:2020, and guidance from Public Health England, laser toys should be Class 1. At four times the Class 1 limit, this toy's "radiation may be hazardous, especially when looking into the beam for long periods."

COMMENTARY FROM LASERPOINTERSAFETY.COM
We do not dispute Mlynczak's technical findings. However, there are some misleading or false statements in the paper that we would like to address.
- An erroneous title; it should be "Laser toy fails to comply…" The case study is not about "toys" plural. It covers only one sample of one toy rifle which had a laser aiming device that was found to be misclassified.
- Stating that the toy laser's output power (1.7 mW) is illegal, when it may have been legal or close to legal (within 0.7 mW) at time of sale.
- Calling the laser's light output "radiation" 14 times and never using the more precise term "light," thus giving a misleading impression the hazard might be similar to that of X-radiation or nuclear radiation.
- Stating without any proof or reference that children "will usually try to look directly into the laser beam."
- Stating without any proof or reference that children "could have temporary disturbances of vision… lead[ing] to a tragedy."
- Stating without any proof or reference that there is such a thing as "hypersensitivity to laser radiation."
- Stating without any proof or reference that "the described laser toy… [is] easily available and [is] still sold as toys in many European states."
- Listing in the References studies claiming laser "toy" injuries, which actually were from standard, non-toy laser pointers.

The following is from the Conclusions section of the report:
"The Ministry’s implementation of the Health (High-power laser pointer) Regulations 2013 and the associated Customs Import Prohibition Order has continued smoothly. The work has not created a large burden for health officials and others involved.
Advertising of HPLPs on auction websites is increasing slowly. Advertising of HPLPs of a power far greater than that on the label continues to be a problem.
In the coming year, the Ministry will continue its surveillance of Trade Me and other websites, and will conduct further discussions with Trade Me on possible additional controls, especially for overseas sellers.
It is of continuing concern that numbers of laser strikes on aircraft continue to increase. [From 173 reported laser strikes in 2017, to 238 in 2018]
Countries vary in their approaches to managing the risks from HPLPs, from raising public awareness to calling for voluntary improvements in labelling. However, there is consistency in terms of the strong controls countries apply to address aircraft laser strikes, including bans and high penalties.
The Ministry will arrange to meet with other agencies, including the Ministries of Transport and Justice, the Civil Aviation Authority, New Zealand Customs and the New Zealand Police, to discuss potential additional controls in response to the increasing laser strike reports."

UK: "Call for evidence" response summarizes many groups' views on laser eye, plane incidents; sets forth actions
The U.K. government published on January 8 2018 a 14-page report on laser pointer safety and potential regulation. The report includes two new actions the government will take to reduce the number and risk of unsafe laser pointers:
1) “strengthening safeguards to stop high-powered lasers entering the country”, and
2) “working with manufacturers and retailers to [voluntarily] improve labeling.
Separately, the U.K. government published the Laser Misuse (Vehicles) Bill on December 20 2017. This makes it illegal to point a laser at vehicles, with a prison term of up to five years and an unlimited fine.
“Laser pointers: call for evidence - government response”
From August 12 to October 6 2017, the Department for Business, Energy and Industrial Strategy opened a “Call for Evidence” consultation. BEIS set forth 19 questions, asking the public to give their views on laser pointer hazards and what actions to take.
The January 8 2018 government response summarizes the 265 responses received.
The report is especially useful because it incorporates the views of many disparate groups: pilots (64% of respondents), “concerned members of the public” (14%), professional laser safety advisors (9%), users of laser pointers (6%), ophthalmologists (6%), and Trading Standards authorities (2%).
The report then distills these views, finding surprising commonality. It is a good overview for the non-expert on two topics:
1) Actual laser pointer hazards — separating fact from fear
2) Potential actions to reduce the number and severity of laser pointer injuries and incidents — including what actions may not work (e.g., licensing).
We have summarized the findings below (click the “read more” link). However, reading the complete document is well worth the time of anyone interested in this issue.

In addition, “new measures are also being introduced to tackle the sale of unsafe pointers, including more stringent testing.”
The move was supported by the British Air Line Pilots Association (BALPA).
It may help reduce the number of laser pen illuminations of trains (578 incidents were reported between April 2011 and November 2017) and eye injuries (more than 150 reported since 2013, mainly involving children).
Consumer Minister Margot James said the ministry is “going further than ever before” to police the sale of unsafe lasers.
The Argus quoted Professor John O’Hagan, of Public Health England’s laser and optical radiation dosimetry group.He said: “Over time we have become increasingly concerned about the dangers of growing numbers of unlabelled and incorrectly labelled high power laser pointers being bought by the public. It is tragic that we continue to see eye injuries, especially in children. Laser safety experts at Public Health England have worked closely with local authorities in stopping large numbers of these lasers reaching UK consumers. The extra protections proposed should help even further - if you have a laser and you don’t need it, remove the batteries and get rid of it.”
From The Telegraph and The Argus. The stories seem to be a result of the U.K. government publishing, on January 8 2018, a response to their fall 2017 Call for Evidence. The government response included the increased import enforcement actions.
See also the December 2017 news of a new U.K. law that provides stronger penalties for aiming at aircraft. The new import/consumer initiative seems to be part of the government thrust against illegal and overpowered laser pens.
On Dec. 22, 2017, Santajoy initiated a nationwide recall of Galaxy Holiday Laser Lights and Northern Lights Holiday Laser Lights. These laser projection products may incorporate a laser having a higher output than intended and fail to comply with FDA performance standard requirements (21 CFR 1040.10 and 1040.11). These higher-power lasers have the potential for eye injury.
Consumers who purchased any of the 5,254 units of Galaxy Holiday Laser Lights and Northern Lights Holiday Laser Lights sold by Walmart between August 1, 2017 and October 25, 2017 should stop using them and return them to any Walmart store for a full refund.
The Galaxy Holiday Laser Lights and Northern Lights Holiday Laser Lights were manufactured from May through September 2017 and distributed from August through October 2017. The affected products sold by Walmart can be identified by the packaging photos and UPC numbers shown below.
Santajoy voluntarily recalled these products after becoming aware that the product presented a potential safety hazard and has notified the FDA of this action. There have been no reports of injury related to the use of these products. Santajoy is notifying the public through this press release, and Walmart is accepting the return of these products for a full refund.
Walmart Stores Inc. distributed these products nationwide. Consumers with questions may contact Walmart via telephone at 1-800-Walmart from 7 a.m. to 9 p.m. CT Monday through Friday or online at www.corporate.walmart.com/recalls for more information.
Note: As of January 1 2018, neither laser was listed on the Walmart Product Recalls webpage. The product recall also did not appear to be at FDA’s recalls webpage or enforcement report webpage, as of January 1. The only online source on that date was the December 22 2017 Business Wire press release, or a few publications and news sources such as KCTV that reprinted the Business Wire press release.
The four Mediterranean islands of Majorca, Minorca, Ibiza and Formentara are popular tourist destinations and are the largest of the group. They are administered as a province of Spain.
The seizures began after authorities discovered laser pointers being sold that were unsafe and/or not labeled according to regulations. Also, pilots were reporting that lasers were being aimed to try to blind the aviators.
Officers from the Directorate General of Public Health and Consumption, the Customs and Border Patrol from the Guardia Civil, and La Palma Local Police inspected the origin and labeling of laser pointers being sold in stores.
Laser pointers are only allowed in toys if they are Class 1 (less than 1 milliwatt) and there is a sign warning parents.
Class 2 laser pointers, between 1 and 5 milliwatts, are for professional use only. Lasers above 5 mW are not allowed to be sold and their use is limited.
From the EuroWeeklyNews
Using Form 2877, the importer must submit information on each shipment and must affirm that the products comply (or do not comply) with FDA laser regulatory standards. But if a small package omits Form 2877 and is mislabeled (not using the word “laser”), this is an attempt to evade FDA and Customs. FDA specifically notes that such single-package Section 321-type imports do not meet the FDA’s criteria for enforcement discretion for personal importation.
Lasers that FDA is interested in include laser pointers, laser gun sights, laser levels, laser light shows, laser pointer key chains, veterinary laser products, laser illuminators and similar products. If a shipment does not meet FDA requirements, it can then be detained by the FDA and would not be allowed into the country.
From STR Trade Report. Thanks to New Aje Lasers for bringing this to our attention.
The new Amazon.com policy requires pre-approval of laser pointers and related products. The products are limited to Class 3R (5 mW) or less and must be branded; examples include Kensington, Quartet, 3M and Logitech. Products must have a testing report from Intertek, UL or SGS.
It is not known if this is a U.S.-only policy or if it extends to other non-U.S. Amazon sites.

The proposal was issued in the Federal Register on June 24 2013. The public may send comments to FDA until September 23 2013. FDA will then evaluate the comments, make any changes as a result, and at a future date will put the amendments into effect.
For consumer lasers, the most significant proposal is to create a new category of specific purpose lasers, “children’s toy laser products.” FDA says these could include lasers intended for creating entertaining optical effects, dancing laser beams projected from a stationary column, spinning tops which project laser beams, or lasers mounted on toy guns for “aiming.” FDA defines such toys as “a product that is manufactured, designed, intended or promoted for use by children under 14 years of age.”
The laser inside such a toy would be restricted to Class I (less than 1 mW for visible light). This is because FDA is concerned that if the toy were broken or disassembled, a higher power laser could harm a child.

7,378 lasers were seized, along with 8,780 parts from which lasers could be assembled. It was estimated that the company sold over 35,000 laser pointers from 2009-2011, generating income of over £1,000,000 (USD $1,600,000).
Techyun Hii, 33, pleaded guilty to four charges of laser pointer violations and a fifth charge of unsafe power chargers. He was sentenced to a 180 day jail term suspended for 18 months, and to 300 hours of community service. The lasers were later incinerated in a hospital’s furnace.
Lead author John O’Hagan detailed the HPA’s findings in a paper presented at the March 2013 International Laser Safety Conference in Orlando. The case had previously been reported by LaserPointerSafety.com.

Laser pointer hazards for pilots
- A study of the actual output of 40 laser pointers, with powers up to 1.5 Watts, showed significant differences between measured and calculated hazard levels. In some cases, the actual hazard measured at some spots inside the beam was three times the estimated hazard. This is due to the laser output not being smooth in all cases, but instead the beams having “hot spots”. The study also showed that windscreens reduced the beam irradiance -- which is safer for pilots -- from 5% to 60%. (Note however that the McLin study described below showed that windscreens also spread the beam and thus increase glare.)
- A discussion of how being inside the Nominal Ocular Hazard Distance of a laser beam does NOT mean instant blindness for pilots and others.For example, consider a 1 Watt, 1 milliradian laser where the recommended safety distance (NOHD) is 733 feet. If possible, you should be at least 733 feet from the laser before exposing an eye to the direct beam. What is the actual hazard? At 232 feet from this laser, there is a 50/50 chance of the beam causing a barely observable retinal lesion under laboratory conditions where the laser and eye are fixed in place. Due to motion of the aircraft and hand-holding the laser, the chance of a retinal lesion is likely to be less. The distance from 232 feet (“ED50”) out to the NOHD at 733 feet is a known “safety factor” where the chance of retinal injury decreases even further. At the NOHD there is a “vanishingly small risk of hazardous exposure” (Sliney, 2013). Police and other first responder pilots can use this information to better weigh the risk of laser exposure to laser light vs. the benefits of completing a mission (rescuing a person, apprehending criminals, etc.). This presentation also discusses ways to make flight near lasers safer for pilots. A PDF file of all the slides presented is here.

The findings were made public at a March 20 2013 meeting of the International Laser Safety Conference.
Researcher Joshua Hadler designed the measurement device to be accurate, inexpensive and easy-to-use. It would cost roughly $2000 in equipment costs to make a copy of the NIST device; plans are available from NIST for interested parties.

The author, Trevor Wheatley, is chair of the Standards Australia SF-019 Committee on laser safety. He studied 41 lasers purchased online in 2012 that were claimed by the sellers to be legal -- lower than the Australian import limit of 1 milliwatt. Most cost less than AUS $20.
Wheatley found that 95% of these pointers were illegal under Australian law, with outputs above 1 mW. Of the 41, 78% were between 5 mW and 100 mW. (5 mW is generally taken to be the highest safe power for a general purpose laser pointer.)
Based on Wheatley's research, "...there would appear to be a greater than 50% chance that someone attempting to buy a 'safe' laser pointer would inadvertently get a hazardous laser." Further, 100% of the tested laser pointers below $20 "would represent prohibited weapons in most Australian states."
From other statistics, the paper states that "availability has not been significantly impacted." In 2007/2008 there were 648 incidents involving lasers pointed at aircraft. In 2010/2011, well after the import and possession restrictions, the number of incidents had increased to 828.

33-year-old Techyun Hii ran Sky Laser Pointers from his home in Ribbleton, a suburb of Preston, Lancashire. In 2011, Lancashire Trading Standards officials found he had lasers that were up to 150 milliwatts, substantially over the U.K. limit of 1 milliwatts for laser pens sold to the public through an eBay store. Three packages were being sent to Greece, just before the Greek riots. He had been warned twice before about U.K. laws and his obligations.
In April 2012, investigators placed a test purchase which led to Hii’s arrest. He pleaded guilty to five counts of selling illegal goods, and will be sentenced July 4 2012.
From the Lancashire Evening Post
UPDATED November 25 2012: Hii was sentenced to a 180 day jail term, suspended for 18 months and was ordered to carry out 300 hours of unpaid work. The lasers sere destroyed by burning them in a hospital’s furnace. From the Lancashire Evening Post.
UPDATED March 22 2013: The case was the subject of a paper in the Proceedings of the 2013 International Laser Safety Conference, “Laser Product Assessment for Lancashire County Council Trading Standards Service” by John O’Hagan, Michael Higlett and Marina Khazova, pp. 181-188. A summary of the paper is here at LaserPointerSafety.com.
On March 25 2012, an ATNS statement noted that air traffic control towers have been illuminated by laser light, in addition to airplanes and helicopters. ATNS said there have been at least two arrests, but thus far, no prosecutions.
South African aviation groups are joining together to publicize the hazards and penalties of aiming lasers at aircraft. They are also considering strengthening laws. According to the statement, laser ownership requires a permit, but illegal sales are taking place via imports and black market stores.

The newspaper report did not have specifics about the lasers’ numbers, power, color, etc.
From Emirat Alyoum. English-language reports from Emirates 24/7 and Bikya Masr.
- The laser product does not have a permanently attached warning logotype label;
- The laser product output exceeds 5 milliwatts;
- The laser product fails to contain certification or identification information either on the product or in the instructions for use;
- The laser product fails to contain instructions for safe use;
- The product class or output information on the laser product's warning logotype label is different from that in the instructions for use; and/or
- A product report for the laser product has not been submitted.
Products which can be Detained Without Physical Examination (DWPE) include laser pointers, laser gunsights, laser pens, laser light show projectors, laser special effects, laser levels, toy guns with lasers, laser pointer key chains, and similar products.
It is unclear what effect the FDA’s import restrictions have on supplies. For example, the well-known company Wicked Lasers is listed multiple times as being banned from importing “All laser products and all products containing lasers.” However, a company representative on December 22 said that Wicked does ship to the U.S. and there should be “no issues getting a laser into the U.S.”
Violating companies are listed as follows.
- Canada: 2 companies shipping from a total of 3 addresses
- China: 51 companies shipping from a total of 57 addresses
- Hong Kong: 9 companies shipping from a total of 9 addresses
- Japan: 1 company shipping from a total of 2 addresses
- Taiwan: 25 companies shipping from a total of 28 addresses
- United Kingdom: 1 company shipping from 1 address
From the December 20 2011 update to the FDA Red List
92 laser sights and 74 automatic machine guns were ordered between Sept. 2008 and January 2010 on Lake County letterhead and purchase orders. The officers paid for the products with personal funds. The amount earned from Internet resales was not stated, although the three officers were also indicted for understating their personal income by a total of $387,000.
The laser products came from Insight Technology Inc. and Laser Devices Inc. The 92 restricted laser sights were purchased for approximately $1000 to $1400 each and were sold on eBay for around $2800 to $4200 each. A special agent of the U.S. Food and Drug Administration (which regulates laser devices) made an undercover purchase as part of the evidence-gathering process in the case.Click to read more...
