US: Man says laser aimed 1/4 mile away caused retinal injury

A San Francisco man says a laser beam aimed from a distance of 1/4 mile caused a permanent injury in his right eye in December 2012. He now uses a magnifying glass, and a computer keyboard with larger letters to do his job.

Tris Thomson laser eye injury

Tris Thomson of San Francisco was in the Mexican Riviera on a sailboat at sunset, when someone in an apartment building aimed a green laser at the boat. Thomson felt “a slight bit of pain in the eyeball. A little searing, like almost you get burnt real quickly or something,” he told KTVU TV, which reported that an “eye x-ray” showed a black blotch on his retina.

The news story quoted ophthalmologist Dr. Vineet Batra as saying that he “sees patients injured by laser pointers about once a month.”

US: California pre-teen stopped from pointing laser at cars

On July 12 2012, in the San Francisco bedroom community of Tracy, California, a 12-year-old boy was aiming a laser pointer from his roof, onto passing cars. Police were called; the boy’s mother took away his pointer and told the officers it would not happen again. The boy was released to his mother’s custody.

Note from LaserPointerSafety.com: We monitor news reports of laser misuse. One reason for this is to try to get an idea of the relative rate of events such as harassment of the public and of sports figures, aiming at automobiles, aiming at airplanes, etc. We see relatively few reports such as the one above, but have listed it as part of this coverage.
