List the specifications of your devices please.

Everyone is different. In fact I use a 2015 Macbook Pro with AMD graphics I am typing this on right now. No problems.

Wow. Nice to here, that the android workaround helped you.

Well currently no one is sure about what the eyestrain reallly causes so its a pitty that I can't give you an answer.

I use an 5 years old Asus Laptop with Windows 7, Intel Core i5 430M and AMD HD 6370M graphics card. It strains my eyes after a while but i can work with it. Whole different story with the 13" Macbook Pro Retina (2014)... It gives me instant eye strain, dry eyes and nausea and all problems started by using it.

    Would be interesting if the new Macbook Pro with AMD graphics would have a different effect on me.

    Artis Do you know if your Asus laptop is CCFL or LED backlit, and if it uses PWM?

      Phones that uses SuperAmoled display technology like Samsung phones (S3, S4, Note series etc) are known to use PWM and has screen flickering. Here is a video of screen flickering on a Samsung S4.

      Has anyone tried this surface dithering root solution on a samsung phone? Does it completely eliminate the screen flickering? and more importantly, do you still get eye strain when using the phone after using this solution?

      I have avoided Samsung phones for years because they give me eye strain due to the screen flickering. If this solution works, then I might consider getting a Samsung phone again.

      I haven't tried this "surface dithering" tweak, but no amount of hardware overlay tweaking in developer options will solve the PWM (obviously) I think OP is talking about color flickering, which is different from PWM.

      However I was looking through source code of kernel for various phones I know to use PWM (GalaxyS6,Nexus6P, etc.) and may know a way to adjust frequency. Hard to tell what PWM function controls what (backlight, vibrator, etc.) as all those depend on PWM.

      I wanted to come up with this thread again. However it seems that the mentionend app development has stopped in 2015.
      Maybe I can turn my Galaxy S7 into an usable device with such a trick.

        Hi, I gave up this idea because I somehow managed to get used to the Galaxy S7. But I also had to do a lot of eye exercises with this smartphone.

            Looking at the Screen with my Prism Flipper. I've glasses with + and - prism and I am changing the prism every 10seconds.

                That thing of the prism flipper is interesting. I am now doing many kinds of eye exercises with an optometrist because one of my eyes work more than the other. I really don't have hope on this exercises because my sensibility to eyestrain is so high I can only use eReaders.

                I suppose you could look for certain time to certain phones and computers before those exercices. Does it improves drastically with the flipper exercise?
