Sweden: Study of 47 laser eye injury cases from 2013 to 2015
The main body of the 2015 study includes an analysis of the laser power versus the observed injuries.
The authors note “If the availability of the handheld lasers continues to increase, along with higher optical power and lower cost, we expect that the number of severe eye injuries will continue to grow. Also, the distance from which the lasers can be used to disrupt various societal functions, such as air traffic (pilots) and policing will also increase. Almost all the reported cases involve young children and teenagers. There is also a huge overrepresentation by males. Often the lasers are sold as toys and purchased by a relative as a gift to a child. Earlier reports originated almost exclusively from developed countries. This situation has now changed and more and more reports originate from developing countries. The problem is worldwide and hence there is a need to educate and inform the societies of this danger.”
The 47 new cases are listed in an appendix. Here is a random sample listing two of the cases:
