  • is eyestrain about polarisation? (vertical vs horizontal)

I think for some it definitely is the cause. I have had the worst luck with LCDs in general which I am thinking is due to how theyre polarized. I know when I wore polarized glasses in the past they made me feel not so good.

    jordan I don't like polarized sunglasses either as they make me feel uneasy, but I never had an issue with older LCDs. Current ones yes, but that's likely due to other forms of technology.

        Clokwork from what I'm aware of some are vertically polarized while others are horizontally polarized. There's also circular polarized which I know oleds tend to use but unsure if any LCDs exist with a circular polarizer. Might be good to note down bad/good devices and how they're polarized. I'm sure it doesn't affect everyone but seems like there are people who definitely are bothered by it. Someone did make a post about using tracing paper to cancel out polarized light but I never tried it personally.

            jordan This definitely opened my eyes to the possibility that the polarization could play a part in my display issues. Thanks for that. Any easy way of testing the polarization methods of displays?

                Clokwork I'm glad! No problem. Hmm I think the easiest way is to get polarized glasses and see if you can see what's being displayed or if it's black. Depending which orientation it's polarized it'll be black or showing the image. I think older screens are black with polarized glasses if I'm not mistaken. If it looks like a rainbow I think that's circular polarized. Btw I remember someone saying they removed the metallic layer in a LCD backlight assembly and it helped remove strain. Was some post on here somewhere
