I was playing with some 3d cinema glasses. Some really cheap ones. One they gave me once i was seeing a 3D movie.
I tried on my Sony XZ 2 (eye-strain phone) and discovered that the left lens has a different effect then the right one.
When i rotate the lens on the phone it seems it goes on all spectrum. Maybe the phone polarization makes this. The violet and blue part are really strong, and green and red are not percitible, instead it's more yellow. Maybe the spectrum is like the blue white led, and the blue spectrum is really strong.
Or it might be that the phone just polarizes blue spectrum differently than green and red, maybe the coating on glass/polarizer, changes the way red and green works.
When i look to from my glasses to Sony, it seems to me that the more accute pain is when i am on the violet/blue part. I feel pain and my leg twiching. That's one of the neurological effects that i suspect blue light is triggering.
On my old HTC one, the polarization is different, so the it changes from a subtle blue to subtle warm, and in a certain angle it becomes color spiral intense. And it's the same on both lenses. Right and left.
I will try to go to shopping and go play with those glasses and phones, and check if i can discovere anything.
I will try to understand if other phones like the iphone XS has the red and green component so strong has the blue on Sony. If it's polorized on the same way. Maybe those glasses just polarize the blue spectrum more intense, i dont know.
