    Lumia 920 is different from all other Nokias due to the new screen PureMotion. So it may be of interest to test the Lumia 920, at least to test the flicker effect on the eyes since Nokia claims the phone to be flicker free.

     

    Another thing i want to mention is that the past month i use a Led backlight Sony netbook, and strangely i get mild eye strain only after a few hours of unstoppable work, which i could say it is near my norm with any of the old ccfl screens. This is really strange since all led screens i used up to now, either in mobile or in laptops used to cause me eye strain and headache.

    Do you get a slightly burning face, sun burn effect on your cheeks as well? Dry eyes? My headaches and dizziness all stopped once i turned of the Wifi bluetooth and cabled the laptops. But the new Retina screen seems to pack a punch on me, maybe i should have gone for the Anti Glare screen, like my last Mac.

    Yes i do, but these symptoms occur even if the wifi or 3g is closed. In my case it should be something with the screen. Definitely anti glare filters have not helped me up to now.

    this is one site that was useful es-uk.info which helped me understand the effects, symptoms etc

    Hi, I am just curious about the anti glare screen you mentioned. Does that take away from the quality of the iPad experience or MacBook experience. Keep in mind, I know nothing about anti glare devices but I have this mental image of a very dark shaded unit that covers the screen.

     

    Also, I am finding that the headaches with the iPhone 5 are the root cause of the problem for me.

    This is a very informative site. On my side though i have never experienced headaches or dizziness from cell phones or cordless phones (i use the devices "reasonably" - do not not know what happens from excessive use). From wifi though i used to feel a bit awkward after some period of use with a dell laptop an employer has provided to me. But i had never experienced such a case with my mac.

    With the new macs/iphone/ipad i get a headache, dizziness, & eye strain with 15min of use regardless the wifi. It seems to be the screen that causes this.

    I have seen a post with a research paper of ANSES (http://www.anses.fr/index.htm) that talks about the negative effects of led lightning. If it is not the flicker effect due to leds on/off, it could be the led lights as a light source that cause my symptoms.

    I wonder if someone on this thread has tested the Lumia 920. That could provide some insight since Nokia claims this device to be flicker free.

    I have had painful eyestrain problems with Imac 2011 and MBP 2012, had to send both of them back. 

     

    My original 2010 MBP 13 inch worked great. It had some stuck pixels, so I took it to the Apple Genius bar and they replaced the screen free under my 3 year applecare plan. Guess what?

     

    The screen they put in is killing my eyes. They have no solution.

     

    The screen is an LG.

     

    Out of desperation I've ordered the Ivisor Moshi screen protector. 

     

    Do I have any other options to sort this out?

    You can either set the screen brightness a bit lower or you can use a little tool called f.lux (google it).

    I never had any problems with macs of several years.

    Just like to add a me to to this.

     

    I just spent 2 grand (UK£ not $) at Xmas and treated myself to a new MBP with anti glare.

     

    I cant look at it for more than an hour.  I get sickness and headaches.  No dizzyness however. 

     

    This is a real problem.  I have hooked my MBP up to a plasma TV and this works much better.  On further investigations a plasma's refresh rate is far higher than that of an LCD.  Im not saying this is a solution but a refresh rate is my guess. 

     

    I came on here to seek advice but stumbled onto this thread.  Im guessing whilst this doesnt concern 99% of mac customers there are still a fair few hundred thousand of us that get dizzy and sick after 15 mins of use. 

     

    I dont want to give up my MBP, I love it, but whats the point of a computer you cannot look at. 

     

    Incidently, my iPhone gives me no problems at all.  My daughters iPad does though. 

     

    Perhaps its not Apple, per se.  Perhaps I have grown intollerant to LCD screens.  As said, I have no problems with Plasam TVs even whan using them as a monitor. 

     

     

     

    You know what.  A though just occured.  Here we are all banging on about how staring into a flat bright object 2 foot infront of us for hours on end causes us problems.  Well duh! come to think about it.  This is hardly what our human eyes were made for.  Sorry this doesnt help anyone but a valid point non the less me thinks.

    Update on my eyestrain issues.

     

    I installed f.lux app which definitely helped but it was only when I installed the Moshi Ivisor that the pain in my eyes went away.

     

    I'm pretty clumsy but  the installation was a doddle. Well designed, designed to eliminate any air bubbles.

     

    The Ivisor turns the screen from a glossy to matte screen. There is some loss of sharpness to the picture but I find it usable and 100% better than looking at the glossy screen without the ivisor.

     

    At least my computer is now usuable again...

    Pleased it worked for you.

     

    Not me or others though.  From reading this thread there are a lot of us here (myself included) who acctually bought the official Anti Glare screen upgrade option and still the sickness and headaches.

     

    If sticking something over the screen works and the official upgrade doesnt Apple really need to go back to the drawing board with their anti glare design.

    I heard about a modification of the graphics drivers in the next version of ML (maybe something for us?)

    aside for the "solutions" presented here, you can also try another Color Profile and Brightness setting (in SystemPreferences/Displays), maybe you can find a setting that solves it for you.

    Hello.

     

    So the veredict?

     

    I have the same problem. After a hour or so my eyes start to hurt A LOT!

    I tryed to put up refresh rate to 85 and then screen went black. So now I stick to 70hz. It seems a little bit better. Maybe.

     

    What about that moshi ivisor? I googled it and it is like screen protector? too bad, that they dont ship to the country I live.

     

     

    Can please someone do a quick veredict of all the solutions that might help?

    I would do it myself, but if I try to read all these  54 paged, my eyes will burn out...

    Unfortunately there is no quick fix for this as yet. Different people suffer different symptoms and you really have to find what works for you! Personally, I have been suffering severe migraines and eyestrain but have found that one of the Macbook screen models doesn't give me these symptoms. That model number is LP154WP4-TLA1. I have been through to a senior adviser at Applecare who is speaking to the engineering dept to see if they can swap out my screen - it's the high-res model so causing problems in that regard.

     

    In the meantime, for those suffering migraines, I have found a great drug which really helps alleviate them. The drug is Sumatriptan and the brand name in the UK at least is Immigran - it's magic stuff. Using this I am often able to carry on with my day rather than being bed-bound with the blinds down.. :]

     

    Keep on searching for the answer people, this thread is a great resource.
