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

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

@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.

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.

@vitruvian8807
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.

@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

@sli121 A three-polarizer system would work.

@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.
