Hello
I'd like to mail order protective glasses for me and the whole family. I need trustworthy and standardized glasses that a professional would use while working with class 3b equipment.
I need IR and green protection. But how dim should the glasses be? How strong glasses does one need to be safe with a) accidental short term exposure to 50mW green? Or b) direct continuous hit from a specular reflection? Or c) to be rescued 99,9% of the time from a direct hit by the blink reflex? Or d) to safely stare into the beam? I'm not planning to do the last, but would like to see the math.
I reside in Europe. I did some searches and found some reviews of recommended glasses. I am shortsighted and need prescription eyeglasses, and so do most of those for which I plan to buy protection at the same time.
