Default Do cheep laser glasses work?

Hi, Iím building a 6.5nm 300mw laser, and plan on getting a cheep pair of laser glasses for 11$ on ebay. Do the cheep glasses provide the same amount of protection as the more expensive ones?

Default Re: Do cheep laser glasses work?

Hmm. I'm not sure where to get glasses for the "plasma extreme ultraviolet" (6.5-6.7nm laser). . .
But, if you want to risk your eyesight to save a few $, go ahead. Many here will not recommend it, and will tell you that a lifetime of (partial or complete) blindness isn't worth saving a few $ now.
The cheap ($10) glasses will not provide the same protection as ($150) certified laser-protection glasses. The $10 cheapo's will melt very fast and not provide protection for more than a few seconds and the $150 certified glasses will provide protection for a lifetime.
Of course, there is a nice middle ground:
Dragon Lasers:
Laser Glasses - Red laser beam protection 600-740nm :: Laser Safety :: Dragon Lasers
Zonestealth:
Protection Glasses for 650nm Red Laser <-- the ones I use for Red lasers

Thanks, I think I will go with the one from laser2go.com. BTW what did you mean melt? like light would bleed through, or the glasses would actually melt?

Question - Why would you need more than a few seconds of protection?

I just put together my first 1W 445nm last night. I have cheapo $10 glasses. My fear is a reflection and/or some sort of inadvertent triggering of the laser. I can't think of a scenario where you would actually need to withstand the beam hitting your glasses for multiple seconds straight. At least, not a scenario that doesn't require doing something intentional (like pointing the laser beam at your own face).

A few seconds, say 10 to make sure the eyewear lasts. Which happens to be the time used in EN207 certifications. When you're standing upright you can move pretty quick, but when you bend over to adjust something you can't move that fast away. So in the situation where accidental exposure is more likely to occur you're in a possition where your balance is not ideal and if you're startled it definately takes a few seconds to move away.
I'm not saying this always happens, but in case it does, it's nice to feel safe with laser safety eyewear that guarantees safety in case of any accident.

Which one do you think I should get if i want to see the beam or at least the dot and still protect my eyes perfectly.
Laser Glasses - Red laser beam protection 600-740nm :: Laser Safety :: Dragon Lasers
or

Well. The laser is listed as 660nm. The second glasses you linked to only protect up to 650nm, and as such are probably not going to protect you at all from 660nm (red).
