Title mostly explains it. In more depth I mean what IS safe to do with a 100mw green 532nm laser? Is it safe to shine it on the wall and look at the dot without protective eyewear? Or must you wear glasses at all times when operating it? (I'm only talking about the 100mw 532nm laser, nothing higher.) And is there a minimum distance for it to be safe to observe the dot without glasses? Help the new guy out, really interested in lasers now and want to start learning all the safety precautions and in time, how to build my very own laser. Thank youuu.
