Ok this is really weird. It was a pain to balance a phone and two pairs of glasses so please forgive the quality.
What we have here is a computer screen, a pair of 3D polarized glasses and a pair of polarized sunglasses.
Polarized light is basically packets of light lined up in one direction. Natural light is not lined up, but once it hits a surface, say, water, it all bounces off in the same direction - polarized. Polarized glasses are designed to block only that polarized light.
Laptops and phones emit polarized light, so at the right angle, the sunglasses completely block the screen's light (area A). However, what I find very strange is when you add a second pair of polarized glasses, the light somehow manages to cut through (Area B). In my struggle to understand, this appears to be related to the quantum nature of photons, but at that point I gave up trying to understand.
If anybody in @steemstem can explain, please do and enlighten us all!
Also, note the blue tint in Area C from only the 3D glasses. When rotated, this turns into a yellow tint.
very nice post my dear
interesting. i have not much to add but to look for more info on the internet and scientific resources.

Nice :) upvoted and followed.
Why don't you check my last story about photos?

To my understanding, there is actually a polarizer covering your computer screen. So now, you are actually having 3 polarizers in front of your camera.
I guess the picture here explain pritty nicely on why you can observe light on Area B :D
And by the way, i feel a bit weird for 3D glasses as they can't completely block the screen light (I am not sure if this is universal, but it happens to me)
Great picture! Maybe it's not as mysterious as I imagined
Oh and I did know about the polarized screen - you can actually fix up the screen by removing it and make it so only you can view the contents with a pair of glasses, everyone else just sees white. It's pretty cool
I find Asians far more attractive, personally
