US: Man stabbed in Pittsburgh after asking persons to stop shining laser pointer at him

A man in Pittsburgh was stabbed with a knife, after he approached two people and asked them to stop shining a laser pointer at him. The victim was with friends on the campus of the University of Pittsburgh, around March 15 2015.

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.”

World: Hobbyist injures self with 1 watt blue laser

A laser hobbyist was injured by a 1 watt 445 nanometer (blue) laser on December 6 2011. The injury required unspecified surgery, possibly removal of intraocular blood via needle. Two days after the surgery, the hobbyist reported a blurry dark circle in his central vision. His doctor told him he would always have a small off-center blind spot, and that his brain would “auto-correct” to fill in the spot.

(UPDATE March 14 2012: The hobbyist reported “I still have the blind spot, and was effectively told by the ophthalmologist that it would probably be there the rest of my life. That doesn't bother me TOO much, since it isn't very inhibiting.”)
