Default How bad is IR from a 10mw 532nm

i was wandeing how bad the IR was from a 10mw laser without a filter.
and where is it located, can holding the laser and looking at the green beam be bad for you.

and, why is IR from a laser so bad, radiation i guess. can someone please explain this.

thankyou.

EDIT: where can i get an IR filter for a laser such as DX 10mw CR2?

You don't need an IR filter for the IR from a 10mW green, the IR would probably be 1-10mW , and would also have a high divergence. It is perfectly safe to look toward the beam, no need to worry about IR. You really don't need to worry about IR unless its from a green thats REALLY powerful such as a 100mW pointer.

even on the high power greenies, the green is going to do far more damage than the IR will, so dont worry about the IR unless you're trying to get a super accurate power reading or something like that.

I have a 5mW green from ebay seller salostore (Note: This is not a commercial post, I'm just trying to provide as accurate information as possible.) and I was wondering about the actual power, IR leakage, and such. I stare at the dot from only a couple of feet away quite a lot, and I was wondering about how bad this is for my eyes without goggles. Also, I have glasses, which seem to make the dot somewhat brighter. How bad is this?
