Is this vid accurate ?

Is this vid accurate?? Form what I know is that these goggles are for diffused viewing only !!! He says that these goggles will protect your eyes from a direct hit for a few seconds !!

Any goggles that are FDA certified must be able to take a direct hit for a minimum of 10 seconds before the dyes bleach

But will that still protect your eye ? Well lets say 100 mw of green from 2 feet away. I think your eye would be toast .

Well I'm not sure if those are FDA certified laser safety glasses, but the 'real deal' glasses should provide protection from a direct hit for a minimum of 10 seconds.

I have a pair of some super beefy argon safety glasses that I fired a watt into (I have a spare set of the lenses) with no ill effect. Much less than 5mW made it through to the other side of the goggles.

They are designed for worst-case scenario, e.g. a static beam directly into the lens for 10 seconds.

i got the cool wrap around pair and they are tits.. 180-315 D L7 + IR L4 >315-532 DM L5 + IR L6

whatever that means..

Whats the OD, that is key thing. D L7 is not the conventional way of expressing the number. IE OD6 is about the best you can do. OD3 is allows you to see much of the beam, perhaps too much.

I have a pair of Argon safety goggles that are rated OD 14 for blue (488 nm) and OD 11 for green (514). A friend of mine put them on and actually looked straight into the beam of a 100 mw DPSS green. (Yes, it freaked me out at the time and I yelled at him!)

But he was unharmed. Afterward, I checked the goggles with my lasercheck to see exactly how much power he was exposed to. I couldn't get a reading - even on low range. I asked him what he saw through the goggles, and he said it was like a dim dot of light, and at first he wasn't sure that he was actually looking down the beam. (But he was...)

I must admit that I've been temped to try it myself, especially now that I've done futher experiments with those goggles and trust that they really do meet the OD rating. But I also like my eyes, so I haven't done it. (After all, at such a high OD, it's not like there's going to be anything to see anyway...)

Bottom line though: a decent set of goggles with sufficiently high OD rating will indeed protect your eyes from a direct strike at close range - even for several seconds.
