So I have just noticed (after 2 years of wearing) that my sunglasses darken certain monitors, give odd patterns to car windows.
And figured out that the lenses are polarised and that’s why.
Just yesterday, I tilted my head to stretch my neck and noticed depending on the angle, the sky was darker or lighter.
But my surroundings (trees, buildings, ground) didn’t change.
Why do only certain things get affected by polarised lenses?
In: Physics
Because these things reflect (tinted windows), refract (sky) or emit (monitors) polarized light.
Normal, unpolarized light goes through polarized glasses the same no matter how you tilt them. Polarized light passes fully if it’s the same direction as the glasses’ filter, and gets stopped more and more if you tilt them.
