RGB Safety Glasses

[Anthony P]

I am searching for adequate eye protection for RGB of about 1-2 watts each. I have checked the usual shops and find glasses that are close but not quite. There is always a gap in wavelength protection. Are there laser filters lenses that could be stacked? I know other people here at LPF experiment with RGB... what kind of eye protection do you use?

Here is one of those "stupid questions". Since a RGB can create the illusion of any color, do all colors need protection or only the 3 primary wavelengths being used. Seems the only sure-fire protection is a metal blindfold.

If you block RBG
Then you can't see
It's just that easy


Laser safety glasses attenuate a range and the protection you get is not a flat line across that range, for instance you may buy glasses that offer OD5+ protection against 532nm and their protection range might be 400-540nm but they may be only OD2+ at 405nm

Look at the graphs for these various laser safety glasses >

RGB glasses are a thing. Laserwave sold them in the past. I had a pair, VLT was terrible, as you'd expect, but you could still see.

Interesting, I did not know a RGB pair of laser safety glasses were made although I have made my own before and yes, the visible light transmission was awful, much like looking through a welders mask.

Another option is to use a VR visor and a cam or similar set up, I had made such a thing for viewing IR beams but I now need reading glasses and need to make another set that will fit over my reading glasses, the VR visor was inexpensive and has a cool color LCD that I will repurpose.
