    I keep hearing from people that LED screens can f' up your eyes because of the flickering or the intensity or something like that.
    If I stay using the computer for too long I sometimes get tired from the eyes and I get some blurry vision, but I figure that's normal.
    Thoughts?

    No worse for your eyes than reading, or CRTs, or CFL LCDs, or OLEDs....

    It's most likely just working with the fixed near-field focus for hours on end more than any shortwave blue / leaked UV from the LEDs.

    Don't worry, before that it was UV from the CFLs.

    And "ultra-mega-gamma rays" from tubes. ;) :D

    perhaps, although there are also many who find LED light unbearable, but CCFL and CRTs perfectly comfortable.

    for me, it is the blue quality and intensity of LED light that I can't deal with.


    To the OP. All screen work is potentially bad for your eyes. As for whether LED light itself is bad, I couldn't say. However, there is a growing number of people who find them hard to deal with.

    What to do is pretty obvious to me...if I find something that is uncomfortable to me, I avoid it. I therefore do not use LED screens at all anymore, just in the same way that I don't spend all day starring at the sun.

    Interesting. I can see the flicker in LED Christmas lights and in some car tail lights, but I've never noticed it on an Apple LED-backlit screen. It's freaking annoying in LED Christmas lights.

    I'm also one of those people who could see a 60Hz CRT flickering from across the room, and that was insanely distracting. If I remember correctly, it was right about 70Hz that I couldn't see flicker anymore.

    Therefore, it depends on the person. Most people would never notice a 60Hz CRT, but if I sat down at someone's machine that was like this, it was so annoying I would immediately change it (it's effectively like looking at a strobe light). I know that I can't claim to have the best eyes out there, so it doesn't surprise me at all that there are people who see things flickering that even I don't.


    Yes, I'm aware that this proves I'm not a teenager.

    I can hear dog whistles (and those high-pitched ring tones kids use) too.
