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.

laser glasses

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!

I'm more confused now than I was before!

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"! 🤣 

 

Mozart was a clever man.

He spent his time composing.

Now he's been dead a long long time.

He spends it decomposing!

 

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!
