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.”)

US: Injury reported from Casio-sourced 630mW diode

A laser hobbyist reported injuring himself with a 630mW “keychain” laser emitting at 445 nm. He had a brief, accidental exposure when he lost his grip on the laser and it crossed a mirror. It hit directly in his left eye. He reported being flashblinded for 30 seconds and had an afterimage for 10 minutes, with the center “as black as black could be”. The black spot stayed for about 12 hours.

More than two weeks after the accident, he reports “... there are no identifiable irregularities. I am certain there is permanent damage in the spot, but it is so far out in [my] peripheral vision, that it is just not noticeable. So I have officially ceased worrying about it. Lesson learned.”Click to read more...
