And while lowering brightness can help a bit it doesn't remove the problem.
And finally there is a major difference between a device that's is lit from the rear and one lit from the front because once again a front lit isn't shining directly into your eyes. Its more akin to having a light on to read”
It is a myth proven through studies. Eye strain when reading is caused by things that cause text to be hard to read.
The "artificial light" theory is nonsense. If the light is of sufficient brightness and neutral enough in color temp then it will be easy to read, assuming the resolution of the screen is high, contrast is good, text is large enough and your vision is OK.
Any LCD or OLED based tablet can adjust its brightness for comfort.
LCDs or OLEDs are shining diffused light. Diffused light is diffused light, whether it comes from the sides of a dedicated e-reader, through ambient lighting or the backlight of a tablet as long as the intensity is sufficient enough to illuminate the text it will be easy and comfortable to read.
As long as your computer has a high resolution screen, has sufficient contrast and can be adjusted to a comfortable brightness then taking breaks away from the screen is unnecessary. It's like low kids used to be told that watching TV close will harm their eyes. That's simply not true.
