Default How dangerous is this laser's IR? (Video included)

Just got my 20 mW greenie from DX (sku.7544). IŽll soon do a review on it. But now on the IR part:

After watching the video, what do you say? Is it dangerous? (And how can DX sell a laser stating that it has an IR-Filter, performance unverified,ok, but still it should have at least some kind of filter, shouldnŽt it?..)

BTW: could I use the 3D glasses as protective glasses for green light?

Thanks,
GWC

Doesn't look TOO much IR is getting through.

Yes you !CAN! use use 3D glasses but you !SHOULD NOT!.

They work !OK!

Try with 1 layer, 2 layer and three and see if they are still "see through"

Try to get MAXIMUM layers that you can still see through.

But if you get a higher powered laser GET REAL LASER GOGGLES!

Can you show a video of the IR on a wall? Any laser beam looked into through a camera will be blindingly bright (pure white in the middle), so there's no way to tell.

Don't use 3D glasses. You should always just use certified laser goggles, although you can use laser enhancement goggles for indirect exposure (Really not reccomended, only if you know EXACTLY what you're doing andyou are sure not even a stray reflection will hit your eye.).

If he does what I did in the last post he should be ok with 20mw.

Still got to be very careful though.

But he really he should get real laser goggles.
