Eye fatigue on my new ipp 10.5?

[Neuronum]

It isn't the frame rate.

In an LCD monitor, LED backlight and liquid crystal pixels are separately controlled parts. And frame rate describes the refreshing rate of pixels instead of LED backlight.

What does it mean? An LCD monitor scans its pixels one by one (from the left to the right), line by line. When it's scanning pixel A, it reads A's information from video card's signal and decides whether to change A's color. Then, it scans next pixel B.

Say, if you are watching a static page, frame rates of 0 HZ and of 120 Hz are the same. Since there is no pixel being changed. Each pixel remains still.

Why do you feel some LCD monitors flicker while others don't. That's because of the LED backlight. Those which use PWM method flicker, while others which use DC method don't.

Pro motion gives me instant eye strain and headache.

Thanks to this thread I disabled it and the iPad Pro is much easier on my eyes.

Anyone who experienced eye fatigue with the 10.5 had a try with the new 11 yet?

 

[hipsheik]

I'm planning to try it.

Unfortunately disabling pro motion did not fix the eye fatigue on the 10.5 for me.

Turn brightness down to at most 50% and enable nightshift.

Unless brightness is down to 30% I also experience eye strain. As I explained before it's not necessary to increase unless you are watching a movie, in this case I change a little, and disable Night Shift (for obvious reasons) otherwise it's always down to 1/3. And disable auto-brightness to avoid surprises.

This link explains why it's bad for you to put brightness at such high levels:

Besides remember this will also decrease your battery faster.

I recommend blue-light blocking eyeglasses, too. They will help A LOT with the eye strain. And, of course, a look into bias lightning:

Which includes removing overhead lamps and putting them in a hidden location (choose one where you will know the lamp is there, however you can't look into it directly). In my case I placed a small lamp behind my LCD monitor.

My entire bedroom is lit this way. This was by far the best thing I ever did, since harsh lights would spoil my experience with the IPP 10.5 under any condition. There's just too much glare and even with the iPAD's improved technology of anti-reflective coating matter it won't do you any good.

I also avoid putting a screen protector in my devices to not ruin this part, and, of course, all the rest that only a naked screen can give:

Record Low Screen Reflectance and Performance in Ambient Lighting

The screens on all displays are mirrors that reflect light from everything that is illuminated anywhere in front of the screen (especially anything behind the viewers), including lamps, ceiling lights, windows, direct and indirect indoor and outdoor sunlight, which washes out the on-screen colors, degrades image contrast, and interferes with seeing the on-screen images. The lower the Screen Reflectance the better. In fact, decreasing the Screen Reflectance by 50 percent doubles the effective Contrast Ratio in Ambient Light, so it is very important.

To visually compare the differences in screen Reflectance for yourself, hold any Tablets or Smartphones side-by-side and turn off the displays so you just see the reflections. Those reflections are still there when you turn them on, and the brighter the ambient light the brighter the reflections.

The iPad Pro 9.7 has a very innovative low Reflectance screen that reflects just 1.7 percent of the ambient light by using a new Anti-Reflection AR coating. It has by far the lowest screen Reflectance of any mobile display, so its image colors and contrast in high ambient light will appear considerably better than on any other mobile display. It’s a major enhancement that reduces the reflected light glare from the screen by a very impressive factor of 3 to 1 compared to most Tablets and Smartphones.

Our Contrast Rating for High Ambient Light quantitatively measures screen visibility under bright Ambient Light – the higher the better. As a result of its high Brightness and very low Reflectance, the iPad Pro 9.7 has a Contrast Rating for High Ambient Light of 301, by far the highest that we have ever measured. See the Screen Reflections and Brightness and Contrast sections for measurements and details.

Hi there,
I keep reading 120Hz is better for the eyes, but the fact is that when I reduce it to 60, I start feeling perfect. Only 10 minutes of use at 120Hz, makes me feel really sick for days. Headaches, dizziness, fatigue... not good!

The strange thing is that after a long time feeling great with my iPad pro 2020, I started to feel the same symptoms again. It is only with one app I just updated and I am trying to find out what is it with the developer.

I would appreciate any thoughts guys,

Thank you

People's visual perceptions vary a lot - just look at the number of posts about people bothered/not bothered by blooming on new Pro's and jelly scrolling on the Mini 6. Go with what works for you as other opinions won't affect how you physically feel personally.
