Default o-like 20 bucks laser goggles rated OD5 and OD6 ?

What do you guys think about these goggles ? 532nm,473nm,405nm laser goggles [OLSG532] - $19.99 : O-Like, Quality Products, Great Prices

it says od 5 and od 6 but for 20 bucks it seems a little cheap!
maybe it is OD5 but it will melt the first time a high power laser is shine on them!

It is the same as these: Focalprice.com offers Professional Anti Green Laser Glassess ,discount Professional Anti Green Laser Glassess,Professional Anti Green Laser Glassess products,low price Professional Anti Green Laser Glassess,cheap Professional Anti Green Laser Glasses

They work great. They leak nothing, and I mean nothing of my 150mW green through. Works good for bluray lasers too.

I bought a few pairs from focal to test out, and a 200mW direct hit of 405nm will still allow approx 20% of the beam through. They may help in that you wont get the full power of the beam, but 20mW is still not safe.

Anybody else try a set of these goggles in between a bluray and a meter?

Most cheap green lasers also emit some IR at 808nm & above. Those glasses won't block IR. The IR is less focused then the green so some don't consider it too much of a hazard if you use your lasers safely.

The o-like goggles let through about 41mW against my 185mW 532nm star pointer!

Wow...that seems incredibly high to me! I know they will always let through IR leak from a greenie...but that would me 22% of the laser's power is IR? O.o

If your measurement is accurate, those glasses are actually an OD of 0.65 and if the allow the nearly 25% of 532nm though, they are really as far as eye protection for any beam greater than 20mw.
This is a problem with cheap laser glasses, all they care about is making a quick buck on glasses with red lenses that probably cost no more than 25 cents a pair to produce and couldn't care less who may go blind by taking a direct hit or reflection from a powerful beam.
