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.”
