Default Congo blue and primary red eye protector

I have a sheets of congo blue and primary red gel sheets. When combined, the effect is like looking through that of a welders mask. I can point my lasers directly at my pupil, and just see the red glow of the LD (keep in mind the lasers are <50mW green). I am wondering if this is as safe as goggles. I tested if IR is leaking through with my camera, but it seems to let as much IR through as regular light--which is close to nothing. It was originally meant for a project fo IR pics of the sun. or just going outside and looking at the sun--which the effect of doing this is like a dim glowing ball. As i said, i just want to make sure this is safe, and will not potentially harm my eyes, as of now, i think it is ok. What do ya think?

Gels fade and burn, and bleach. Dont trust them, get the Od6 material that has been tested. I speak from experience that the congo blue WILL fade.
