A comprehensive resource for safe and responsible laser use
The 44-year-old driver stared into the laser several times, as he tried to identify the person holding the laser. He suffered blurred vision in his right eye immediately after the exposure, but waited 6 months before having his first complete eye exam.
The exam showed “spot-like retinal pigment epithelium disturbances temporal to the fovea of the right eye, with no abnormalities in his left eye.” The authors stated that “The subjective complaints and objective ophthalmological findings of this patient were consistent and strongly suggested that the repetitive exposure of the eye to the reflected laser spot 6 months previously had caused subtle but detectable injury to the macula.”
The authors concluded with two “Learning points”:
- “We suggest that no laser pointers of any class are made available to children, since they are unlikely to understand the risks of permanent retinal damage.”
- “For the safety of users and the general public, even low-energy handheld laser pointers should not be sold to children.”
The authors did not identify the location of the incident, but it may be Germany since three of the four authors’ institutions were in Germany. Additional analysis and commentary is below (click the “Read More…” link).

The laser pointer had no markings so the power is unknown. This also will be studied so the strength of the beam is known.
According to police, the laser pointer attack was a dangerous assault. If there is also significant permanent damage to eyesight, a charge of aggravated assault may be considered.

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.”

The Champions League game was played October 18 2011 in Naples, between Bayern Munich and Napoli. Others on the Munich team had different opinions. Sports director Christian Nerlinger said “Laser points are not acceptable. It is a major disturbance and an impossible thing to do,” while midfielder Bastian Schweinsteiger said “Of course it is guess [sic] but I think there is little you can do about it.”

He told interrogators that others “have often been blinded in the same way.”
