    Gurm42, if I remember correctly, the Lumias use OLED.

    Not sure about that model you have tried, I found that some of them seems to have PWM (e.g. Samsung Galaxy S3).

    It could be the flicker that is giving you the troubles?

     

    LovesDogs0415, it's ok :)  do you feel noticeable eyestrain when looking at your husband's iPhone 4? Cause if not, the polarized sunglasses test may not give much meaningful results.

    But thanks nevertheless!

    I would bet on the green tint as being a big part of what's helped.  There was some talk about Gunnar glasses earlier in this thread; they're yellow-tinted glasses that are specifically-designed to cut down on eyestrain.  What they do is filter out some of the blue light, again backing up your "type 3" eyestrain theory (assuming they work).  BTW for years I've used a greenish background in my terminals and text editors because it's more restful to my eyes, but I never knew why :-)  Also, earlier in the thread someone tried an experiment where they somehow disabled the red and blue components of the monitor (I don't remember if it was through hardware or software means) and found that their eyestrain reduced very significantly.

     

    Now, maybe controlling polarization is also useful; it'll be interesting if more people experiment with this.

    rohanzsta,

     

    As far as I'm concerned, the first problematic iPhone for me is the 5 but some will tell you about the 4s and maybe the 4.

    When I first saw it, I told me "Wow that's really too much contrasted".

    But AMOLED screen are too much contrasted & oversaturated as well and I've never had a problem with them.

     

    Now I recognize Apple "bad" LED screens directly:

    - You have problem with looking at black texts.

    - The issue doesn't go away when you decrease brightness.

    - Monitor adjustement and software may help at first sight but then the problem comes back quickly.

     

     

    Now, let's talk about the "blue" theory. As well as the "glossy" one.

    I believe they're aggravating factors but not the issue.

     

    Why?

    Simply because I and many others have no problem with older devices such as the iPhone 3GS.

    I have this device in my hands and I can tell you the screen is blueish, the screen is made with a glass panel and use the LED technology.

     

    Furthermore, my friend lent me a iPhone 5 with the "yellowgate" screen (you can google that). You know the issue where people complain about their screen being way warmer than their crisp blueish iPhone 4.

    And it causes me pain. As well as all the iPhone's 5 I tried at the Apple Store.

     

    My conclusion:

    You can try whatever setting you want, being glossy or mat, blue or yellow, if the screen causes you eye strain (this "anormal" eye strain), nothing is going to change that in the long run. (Unless you can have access to the software that controls LED backlighting?)

    Thanks for the details logoo88.

     

    Definitely agree with you on the fact that "If the screen causes you eyestrain, it doesnt matter what kind of gloss you put over it.. eventually it will hurt."

     

    After reading these threads, I think I'm going to just go to an Apple store and mess around with a 4S and a 5. Hopefully one of them works out.

     

    I'm also starting a new job in SF soon and everyone over there only uses the latest Mac laptops/displays..... I'm in trouble.

    Eric, The Lumias do use OLED, and I bet the one I was holding at the time DID use PWM. I've since checked out other Windows Phone models and not had a problem (but I have a lot invested in my iPhone4s and its apps).

     

    rohanzsta, have you actually tried a Retina MBP yet? I've been very up and down over mine but it is DEFINITELY less problematic than any other Macbook from recent years. Also, if everyone in the office is a Mac nerd, odds are SOMEONE has an older Cinema Display that they have upgraded to a Thunderbolt Display, and the older Cinema Displays are GREAT to look at!

    Stress can be a factor, but remember, that none of us that have this LCD eye strain problem have any problems when reading a book. (This is an assumption based on what I experience, but I'm pretty shure it applies to others as well).

     

    So LCD's should be as easy on the eyes than reading a book, but most are not.

     

    Lumia 920 uses and IPS display.

    rohanzsta et al,

     

    if you have to use Mac laptops, and if neither of Gurm42's solutions are available to you, then you might want to consider changing the display resolution on any problematic Macs. I did this on my MBP a few months ago, from its native one of 1440 x 900, to 1344 x 840, and, whereas before I couldn't look at the screen for more than 15 mins without pain/ strain, now I work on the MBP pretty much all day without any problems at all. As currently set, the colour temperature isn't a big factor - I have it on 6500, gamma set to 2.4, and the display doesn't seem blocky or ill-defined to me. I think I played with the contrast too.

     

    Obviously, this isn't a solution for the devices where the resolution can't be changed, eg iPads, iPhones, and, also, is not as satisfactory as having a problem-free, hi-res device in the first place, but, if it might work for other sufferers as it's worked for me, it's certainly better than either being tied to a CCFL monitor or else squinting through tinted (blue-light filtering) lenses at a dim, funny-coloured screen - all of which I tried, and none of which made any real difference to my discomfort! :-)

     

    I have flagged up this solution (for me) before, so sorry for the repetition if anyone had read that post - I just don't want to think that anyone will have to go through lots of pain which might be avoided if this approach might work for them too.

    Gurm42 ,

     

    What year(s) were these Cinema Displays made in that you're referring to?

     

    I see that the newer ones are all LED based, so I'm interested in hearing when yours was made.

    I do have brand new iPhone5 since last week and while working on MBP is impossible I didn't notice any problems caused by the phone whatsoever. I was worried it might replicated the problems I'm having with the new MBP Appple has given me as a replacement for a faulty MBP early-2011, but it's not.

     

    In the meantime I've gotten a diagnosis from Apple Service Provider to which Apple has forced me to send my replacement MBP 2012. And they claim the screen is fully functional and passed their tests. Tell it to my eyes!

     

    I did try (almost) all the solutions mentioned on this thread and failed to make my MBP workable.

     

    I think I have reached the dead end. It's time to give up MBP and go back to good old PC's. It's gonna be quiet complicated when it comes to my occupation which is filmmaking, but still I can't make films without eyes, right?

     

    I'm also disappointed with the Polish staff of the telephone support. I wish we would have Apple Stores in Poland

     

    One more thing - I have both, sent them the link to this very theard and mentioned it in my phone conversations and guess what - they don't give a ****. Save yourselves, save your eyes. You won't buy them in the Apple Store if they fail...

    mvanier:  It was me who did that green monochrome on the MacBook Air previously I used a program called SuperCal and manually did some extreme adjustments to "calibrate" my screen to show only green. It did help me look at the screen longer when I was sitting directly under the harsh office fluorescent light.

     

    It seemed to be the blue light that was giving me the problem back then.

    However, as I understand more about the eye strains, I now get to realized that it's unlikely the blue light that was giving me problems on my MacBook Air (11" 2010 model).

     

    I have looked at that same screen again recently, unlike the iPhone 5,  I'm pretty sure it wasn't the "type 3" issue. The light itself doesn't look harsh and doesn't induce migraine. So, setting brightness, wearing sunglasses or the rosy red glasses didn't help me with it back then.

     

    I now come to believe that It was the hard to detect mysterious flicker that was troubling me. What I referred as the "type 2" issue in my previous posts. Somehow my eyes needed to work hard to maintain focus on the texts, and then my eyes went exhaused after some time and got seriously uncomfortable.

     

    The reason why the green monochrome helped my eyes was rather interesting. Somehow the texts appeared more "stable" when the screen displays only green. Perhaps the mysterious flicker has less effect on this pure color, it helped the texts stay relatively sharper and thus make them easier to read. Also, the fact that the eye being more sensitive to green probably also helps me interpret the texts with a little less effort. Thus, my eyes were less likely to get exhaused and I was able to look at the MacBook Air longer.

    I experienced the same issue as with the MBP with iphone 4s and iphone 5.

    rohanzsta: I believe the Cinema Displays that Gurm42 referring are those aluminium ones. They are CCFL displays and I think they have stopped production since late 2010.

     

    I agree that they are great displays to look at! For myself, I finally settled with an aluminium 23" Cinema Display after trying many different monitors.

     

    I also agree with FNP7 that changing the display to a non-native lower resolution may help! This method seems to help with those suffering from the mysterious flickering problem.

    It helps with my MacBook Air.

    I'm currently fighting with extreme eyestrain now. I suspect it is the fluorescent lights at work. Ironically, the MOST comfortable thing I've looked at all day in the last few workdays is the retina MBP. But... I know for a fact that other problems exist with that unit so it could certainly be exacerbating any problem that exists.

     

    Right now I'm experimenting with those "as seen on TV" blue-blocking wrap around sunglasses. They seem to be reducing glare and increasing comfort, at the expense of clarity - meaning that it's harder to focus up close with them (they are designed for driving, which explains that).

     

    If I get home tonight and my eyes aren't as sore, I will probably invest in some simpler tinted wraparound glasses.

  • 748. Re: Eye strain from LED backlighting in MacBook Pro
    Eric Leung1 Level 1 Level 1 (5 points)

    I suggest you may have a try with those FL-41 tinted glasses. I got a pair from this website (axonoptics.com) originally for my LED eyestrain tests. I found it particularly effective in some scenarios like the uncomfortable fluorescent light that you are experiencing, and doesn't seem to affect much in terms of clarity for reading and computing tasks. Though of course, everything would look a bit red.

     

    And if possible, try changing the fluorescent tubes or even the ballasts above and near your desk area, I found that could make huge difference sometimes! Enviromental lighting has big influence to our eye strains!

  • 749. Re: Eye strain from LED backlighting in MacBook Pro
    Gurm42 Level 1 Level 1 (0 points)

    So the blue-blocking did help somewhat, at least during normal use. The problem is that they make everything at CLOSE distance somewhat harder to focus on (as they are intended for driving and distance vision) so after a full day of computer use my eyes were still tired (albeit nowhere near as bad as without the glasses).

     

    I am going to invest in a pair of rose-tinted FL-41 glasses, from either TheraSpecs or AxonOptics, and see how those do. They are intended to eliminate pain and sensitivity to fluorescent lights!
