Eye-strain is not caused by the fact that a screen is backlit.
A Paper-Book shines light into your eyes the same way, by reflection.

Eye-Strain is caused by:
- too much brightness. Your screen should not be much brighter than your Surroundings.
- other bright Light-Sources in your viewing area. Bright Lights should be above you or behind you and shine straight down only. Look at Office-Lights, they have Grid-Reflectors for this reason.
- Wrong Distance to monitor. If you have read alot of Books, your eyes might have permanently adjusted to this small Distance for reading (thus the eye-glasses to correct this) and reading at a bigger distance requires eye-muscle work and those get tired quickly causing the sensation of eye-strain.

Eye-strain is always a muscle-issue, there is nothing else in your eyes that could cause this sensation.

I had huge eye-strain issues myself and even gave up Desktop-PCs completely (Laptops were fine) until i noticed the importance of all these 3 Factors.
