I'm planning on doing an episode about using Lasers soon and was looking for some safety glasses. These very cheap ones on eBay were among those I examined, however, I'm having a bit of trouble understanding the description.
While I just LOVE all of the great deals we can get from China I find that sometimes the translation to English leaves a bit to be desired. In this case, I have absolutely no idea what they are talking about.
I'm glad to see though that "the surface is not afraid to wear", I wouldn't want the glasses to get nervous while I was using them!

LOL i had to read it 3 times to try to make sense of it and sadly im no closer
Really guys? They mean wear on the surface of the glasses, even scratches, will not reduce its effectiveness at protecting the eyes.

That's how I read it. They are basically saying that the absorption of the laser light is a property of the entire lens material and not a property of some thin surface coating.

I would be more worried about the "high decay rate"! ?

On a serious note, I can't honestly believe that you have even considered buying safety equipment from China. As someone who has worn a hard hat and safety boots virtually all my life, I would definitely advise against it, even if they do have a CE mark and quote some made up ISO number.
Back to a more lighthearted vein:
Now you have changed the forum to include Artificial Intelligence, perhaps you need a section for Natural Stupidity ?
Or a section called "You've got to be f****** joking!"

I actually wasn't intending to buy them, or anything cheap like them - my eyes are too important to me. Your comments regarding certification are definitely worth noting, thanks!
I agree fully with buying something that is accurately certified. I'm still in the research stage and if anyone has any advice I'd appreciate it. I suspect that I might need a different set (or lens?) for different wavelengths of Laser beams, but perhaps there is a "one size fits all" that is reliable.
I'll be experimenting with tiny red lasers and more powerful (cutting) blue ones if that helps.
Thanks!

I suspect I'd quickly run out of hard drive space for that one!

You might want to take a look at IEC 60825 and ANSI Z136, for starters!
Plenty of information there!
I suspect that the higher quality safety goggles are tuned to a particular wavelength, I would be very cautious of "one size fits all", considering the damage lasers can do!
