A comprehensive resource for safe and responsible laser use
Afterwards, the boy could not see clearly and had a black spot in his visual field. He kept this from his parents for about three weeks, after which the boy was seen by Professor Stefan Dithmar and Dr. Stefanie Pollithy at the University of Heidelberg Department of Ophthalmology. Their diagnosis was “acute bilateral impaired vision and central scotoma.”
A journal article in Der Ophthalmologe has more information, but the full article requires a subscription. Jochen Pernstainer, who told LaserPointerSafety.com about the case, kindly provided several details from the article:
- The schoolyard exposure lasted several seconds
- The laser pointer was measured at 55 milliwatts
- The boy had impaired vision and a black spot on both eyes
- Nine weeks after the exposure his vision got a bit better

Dithmar told a local newspaper that the German Product Safety Act prohibits the sale of products that might cause harm to health, but “there is little that you cannot get on the Internet.”
