Eyelids?

Would your eyelids protect you from a 100mW laser? Basically, can you get eye damage with your eyes closed?

Thanks!

Not with a 100mW laser, your skin will absorb all the light, but a 200mW+ laser focused to a small point can burn your skin, although I doubt that it'll damage your eyes if you have your eyelids closed.
BUT your eyelids alone won't protect you from direct hits or reflections since your blink reflex can't protect you at this kind of power. You need to get some goggles. ;)

Yep, that's what I thought. I have goggles, I was just curious about eyelids. I dont see how you can own a >100mW laser and not own goggles. :D

Your skin/flesh is actually a great blocker of green laser light. Try shining a 30mw green through your finger in the dark. The glow won't even reach the other side of your finger.

Do the same with a 5mw red and it makes your whole finger glow red.

Hence the red 532nm protection glasses. Look at a red laser through these glasses and see if it dims! (don't, it won't - I was being sarcastic.)

Yes, I would not suggest using these "eyelids" as red laser protection ever. I once pointed my red laser in my mouth. It reflected all through my head, and my vision started turning red!

No it didn't.

haha ;D! I just tried it. Doesn't work. :( Maybe he did it up against a white wall were it reflected out of his mouth onto the wall and back onto his face, because that's what just happened to me but it was the computer screen.

I'm not sure why it happens, lol. It is a fairly powerful DIY red though. I made sure it wasnt focused so I didn't burn my head.
