ok some of you may thing this is a crazy un-safe idea, but it actually works...about a year ago i had bought some anaglyphic glasses for an experiment with my monitor and its 3D capabilites...it failed by the way...lol anyway, as most of you may know that the anaglyph consists of having a red/cyan filter and some may have yellow/green but red/cyan is the most commonly used one. and the fact is that, the red filter blocks out almost every wavelength in the spectrum apart from its self and thats obviously red. so i decided to use it as a protection from 445nm laser, i have 4 anaglyph glasses...so i took out all the glass lenses and stuck two on top of each other, and stuck them on to the glass frame, so i ended up with two dual red lenses....and when i turn on my 1.5w +- 100mw laser pointer...i see no laser beam i see no light inside the diode and i only see a very very very dim dot... i didnt have the balls to look directly into the laser beam itself however. but when i put the lense infront of the beam and put a match behind the lense it wont burn it at all. so im guessing it works. :D

please no negative reputation :p i know some may thing its a stupid idea...i jsut want your comments and ideas lol, that is all.

u can get them for very cheap from ebay

U said I'n Yoyr post you see no laser light from the diode. This means you looked into the laser itself? Retarded. You sir, are not very smart.
Even if your wearing ten pairs of od+7 goggles you NEVER EVER look into any laser

no i didnt look directly into it....dude u can see the fricken light by looking at the diode from a 90degree angel....did u not use your brain before you posted that stupid comment? just because i said i didnt see any laser light it doesnt mean i looked directly IN the module.....

Well you may want to change your post. I read that, and stopped reading, because I misread it I guess?

Did I not use my brain? Why yes I did, obviously you didn't, your the one using 3d glasses to block 1.5W of 445 laser light :crackup:

I think you're playing with fire.

Make experiments with glasses that are not designed specifically to block laser :eek: I think it's crazy

The safety laser goggles Designed to block specific wavelength, usually are made with a polycarbonate with a dye mixed into the material, or with an absorbing or reflecting coating, etc.

Also Absorbing glass filters generally provide higher optical densities, better VLT values but at a slightly higher cost per pair when compared to polycarbonate safety eyewear.

That you point out, no idea what they are made​​, so I never play with them with a laser.

Personally do not play with my eyes, I have only 2 and are for all of my life.

Sorry but IMHO think it's an unfortunate post, sets a bad example on safety.

im not really sure, you should try it though :p

You Weren't really telling anybody to tey it eh? You told him to try it, without even trying it...

Are your eyes worth $9 or $50 for a good pair of goggles?

Also, it may make the laser seem DIM and not BRIGHT, but that does not mean it is blocking the actual harmful laser from hurting your eyes. Hell a pair of sunglasses would make it seem LESS bright I would assume.

hmm i suppose but i tried cutting paper and lighting matches and it still wont light it. so im guesing it absorbs wavelength, infact i know it does because thats the whole point in anaglyph, it needs to block all other colours aka. wavelengths for it to work. so it does work abit, especially if you had a lower powered laser, then it would really work. anyway stop arguing it was just a test id done and let yous all know thats all..

Well too bad, you started a bad thread that could potentially lead to somebdoy trying it and hurting themselves, so you need to stop arguing, or change this thread.

Because this IS NOT 445nm protection glasses, whatsoever
No matter how bad you may think it is. ITS NOT

yeah its not rated for 445nm protection and its not certified, im just saying it may work abit, and i bet you all other safety glasses use theese same filter coats anyway :L

I don't think the object is to find the cheapest pair... you really can't put a price on your vision. Try Dragon lasers, O-like, OEM lasers or laserglow.

You are all approaching this the wrong way. About a year ago, I made a post very similar dealing with the cheap protection goggles found here, which now several people use:
http://www.focalprice.com/LP076X/Laser_Promotion_Professional_Anti_Green_Laser_Glassess.html
Price doesn't mean anything. If it works, it works. To test it, it's best if you had an LPM. Also, you should try shining the laser through the goggles, focused, for an extensive period of time in order to see if the dye breaks down. The problem with some cheap solutions is that the dye melts very quickly if it's focused, and then the light will leak through. When I tested mine, I shined a focused 110mW 405nm laser on the glasses for >10min. It didn't break down. You should do similar tests on yours if you want to recommend them.

Overall though, I don't see the point too much, since http://www.focalprice.com/LX166G/Protective_Blue_Laser_Safety_Glasses_Goggles_Green.html sounds like a fine option to me (however, I did NOTTTTT test these goggles at all. >1W lasers might be too much for this to handle).
