I believe there needs to be a warning about the "red" safety glasses o-like sells (blue lenses). While they seem to be excellent at blocking some wavelengths, they do very little at the 6??nm of my 16X DVD burner laser. I may have damaged my vision. I can very clearly see a 1' (one foot) defocused spot with them on. I was burning my name in some wood and now my vision seems a bit funny. That isn't to say they aren't effective at all frequencies. The LEDs on my answering machine disappear when I put them on as do the green ones on my Kensington power switch. God knows what frequencies the do block though. I can clearly read the red LEDs on my clock.

I am also generally disappointed in the host I got from them as well, but metal shavings left in blind tapped holes are more of an annoyance. They aren't necessarily going to hurt anyone. You have been warned.
 





You will see the dot other wise how will you know where your shining it ?
Try shining the laser through the glasses (please don't wear them while your doing this)
and see that the dot will be dimmer. The glasses are for a specific wavelength only

Cheap Chinese glasses are generally rubbish anyway ;)
 
Yeah try shining the laser through the goggles. Doesn't look like it's blocking red light though
 
Try some online vision tests. Search them on the safety forums in lpf...
Yeah the goggles are crap. I got them too... :beer:

It goes right through. Like I said.

The power will be significantly less than without, the OD rating will be rubbish but will still protect you from a flash

OD rating lol.
ALWAYS ONLY buy safety goggles from a CE certified source with a rating of OD 4+

If your laser go bust and you wasted $500 USD .... $3000 USD.... $200000 USD.
You can always make the money back.
But you can 't earn your eyes back.

Well... unless the loan sharks gouged your eyes out for not paying back the $200k loan
 
The best and easiest way to check is shine the laser through the goggles at an LPM. You can then see whether they actually work. Often you will see a red dot through blue glasses as they are designed that way. If they werent, you wouldnt be able to see where you were pointing. They are however supposed to reduce the intensity of that dot by several orders of magnitude.

Googles that block 532 do this as well - you will clearly see a bright green dot! I have eagle pairs and started a thread about it, as I could actually shine my 5 mW 532 through them! It turned out that the goggles did actually work though, as I could not measure anything on my LPM.

From your pic above it really does look like those goggles are doing nothing, but if you wanted to be absolutely sure; use an LPM. :beer:

You saw a bright green dot but you couldn't measure anything? :thinking: even my WL goggles make a 100mW green laser into barely anything on a white wall
 
Oh well if it isn't a bright dot then you're probably fine as the output is probably under 1mW, as your linked thread suggests (or so I believe, if I missed a part let me know)
