hmm, just a totally unrelated question. but i wanna purchase some goggles cuase i just realized how rubbish life would be if i was blind, but i dont have much of a budget cuase i spent all my money on the 100mw and am spending most of it on 2lasers from a forum member. so i only have about $20 left. the wavelenghts i am looking to protect from are green and red, 532nm and 650nm i think. so anyone know any good goggles that will protect my eyes for a good price? i know you cant put a price on your eyes but i only have $20 and having something is better than nothing right.
and also, is the higher the OD the better the goggle? so a 2 OD would be worse then a 5-6 OD? becuase i want to reduce my 100mw green to about 1mw, and my red 100 to about the same, so what OD would i need?
