Every time I type it on on google I get 90 dergree, but I have one it doesn't work. Am I doing something wrong, when I hold it to the screen, it does not work>
Not exactly sure of your question.
But if you hold 2 polarized lenses @ 90 degrees to each other you will not be able to see anything.
A simple check to see if the unknown is polarized or not.
Please elaborate on your question.
Oh I meant for 😀, my Plarizer was damaged, I got a 90 degree from aliexpress, It is the wronf kind. The screens goes dark. Would these let me see the screen?
First What polarizer did you damage and replace?
If it is for your monitor you need standard for landscape/normal mode and 90 degree if used in portrait mode/taller than wide. That way the polarizing lenses are in a horizontal position/plane when viewing.
