Why too much screen time causes eye strain? what is the difference between looking at the screen and looking outside

Question

Only thing I notice we blink less while looking at the screen, is that the only reason? Or are there other reasons?

Answer 1

The reason actually has nothing to do with brightness. It’s because your eyes are designed to function in a 3D world- screens mimic this world but are decidedly 2D.

The eye strain comes from your eyes trying to see depth when there is none to see.
