Default Re: Homemade Safety Glasses (Violet, Blue & Green)) Don't SAFE

My intention was never to endanger anyone, but rather to know how much danger I found myself!

I never said that this goggles were safe or can work properly, is more, I just wanted to know if they could get to work well, and only wrote this post when I saw the results of the tests I did ...
I know that they have no point of comparison even with the Chinese, of course! But when I saw the dot was barely visible, and with no burning power, i wanted to ask if they were as safe as they seemed to my eyes...

On the other hand I did a video yesterday of the test, I figured it would look better than the photos, I thought that if I did it would look better in the dark any light coming through the glasses (i'm doing another video with better ligth):

the first laser used is 1 Watt Blue (445nm), focused to the smallest dot that can give about 5 cm (if instead the glasses were a cd case, this will being burned) and in the black rug i've used hasn't any mark (without goggles it mean big big hole in it (with ANY laser that i've used))

How we can do an aproximate measurement of the possible OD level that it has?
