Melted my safety glasses

[bobo99]

So.... yea.

Got m survival laser in the mail the other day and wanted to see how much the light blocked out. So I took the laser and shone it through the googles (goggles were not on my head, thanks) and kept it there for maybe 3-4 seconds.

The next day I realized the glasses were damaged. First thing i thought was I scratched them but immediately realized that it had a distinct "melting" pattern.

Should I cover those parts of the goggles with some dark tape?

Thanks!

If you have something white or blue to cover it with, that's going to be your second best option.

Replacing the glasses is the best course of action...

If it makes you feel any better, I ruined sunglasses clipons that I really like the same way.

Get another pair, and use these for IR testing in the future...

I would consider replacing them since the melted spot is in the part of the lens you're likely to be looking through at some point.

I tested a pair of o-like goggles the same way, but carefully aimed for an edge that i can't even look through when wearing them. A 1 watt 445 melted a hole clean through in a bit over a minute while focussed at infinity.

Maybe it sounds silly to test goggles like this, but it does reveal something about quality: If you actually melt or burn the glasses, its a good sign. If they use some inferior dye that bleaches out, at least you'll know not depend on them.

Thanks guys ! Doesnt make me feel any better!

How will I use them for IR testing, since these don't have any IR blocking power?

 

[InfinitusEquitas]

True, but they block the other wavelengths.... Think about it for a second

You should have never keeped it in 1 position. When testing Laser safety goggles i like to move them back and forth so the beam will not damage the goggles.

I have those same pair of goggles and hit them with my 2W+ laser with no damage:


Next time you try this or any of you try this Please do what i did in the video.

Hope this saves some of your goggles.:beer:

These Goggle are amazing.!!!

 

[bobo99]

I guess if I had a LPM (laser power meter?) it would work, but I dont

 

[lazeerer]

Well To test Goggles you kinda do because you should be wearing another pair of goggles wail doing it witch will block the light so you wont be able to tell anyways.!!!

 

[JimBolder]

Yeah I made the same mistake when I tested out my first goggles with my 180mW red.

It only melted a small pit on the lens, so I was able to cover it up with some tape and live with a tiny blind spot whenever I put those goggles on.

But in your case, it sounds like you're probably gonna need a new pair.

Cut of a tiny section from the side and glue it on to the front :eg:

that sounds like good idea Lazerz, it would be hard to get the pieces to match up to the edges and where they connect (with some sort of adhesive) i would imagine would skew the optics...but has to be better than tape.

As for the testing glasses, from what i have seen you actually are supposed to hold to one spot but for usually only 10 seconds...like ANSI standards does. I guess they expect one to realize somethings aburning or some other way. I dont remember at the moment what CE, European standards, says about typical testing. They also have a different rating system. But some people check for longer, like when total failure occurs, etc.

If you cant get the piece of plastic to fit perfectly just awkwardly glue it in with clear glue

Its better then nothing

It's the european standard (EN207 and EN208) that requires that the eyewear does keeps it's rated protection level for 10 second or 100 shots, the ansi standard only requires that the OD is high enough to stay below the MPE.
But the eyewear doesn't have to be undamaged after a direct hit, as long as it doesn't pass too much laser light.
