@TheFiery There actually exists some "black light". The non-visible spectrum. =) And you can easily cook food with that in your microwave. But there's nothing to worry in this case, of course.

@vitruvian8807 That WOULD be really cool if it was possible. You can only mix out some light with polarization. Not mix in light that others don't normally see.

@XMikexSonicX No need to worry, there is no "black light" - all light coming from the monitor is blocked, no light comes through.

@vitruvian8807 That would be awesome! Unfortunately, if the sheet results in black for the human eye, the glasses wouldn't be able to resurrect the image on the wearer from black

Just curious but could it damage your eyes when looking at an lcd monitor and seeing that black light ?

It is really cool, but that won't work.
So what you happens in the video is:
polarized foil in glasses hits 90 degree to the foil in the screen and blocks all the light. So no other sheet will unblock it.
Now what's really cool. is having a polarized sheet covering your entire screen, and using polarized glasses to see the screen while everyone sees a black screen.

@sli121 A three-polarizer system would work.
