LEDs may cause retinal toxicity at occupational domestic illuminance
It was a Q-Switched, Xenon pumped, Neodymium Garnet laser intended for Photo-retinal Welding.This pulse laser was so powerful that at discharge through the microscope it could create a white spark in mid-air; theso-called waist area.I Hired on to CooperVision as a Developmental Tech, I inadvertantly grounded a flash-circuit while the laser exit facealigned to my eyes.The Fluke Meter actually bounced a centimeter into the air at discharge, and I saw a moderate orange glow for a bareinstant.Immediately after, and today, when I gaze into a clear blue sky, I see a "small dounut shadow" of two to three degreesin my mid to lower right field.The contrast of the Donut image has decreased over the years but decades later, I see it.
What do you Know? I got shot with a surgical welder.-No worries though, No worries at all.
