Why does looking at computers screens makes eyes hurt?

331 views

I know we blink less while using screens and the dryness of eyes could be causing the pain. But staring at plants without blinking doesn’t cause asmuch pain. Maybe the emitted light is the culprit, similar to how eyes hurt while staring at the sun, streetlight, etc.

Also, why does looking at something which emits light hurt in the first place?
(Because E-ink display do not)

What’s the science behind this?

If im not wrong, computers emit large amounts of blue light. Blue light bad for eyes -> cause eye strain ->pain.

Sun -> huge emitter of infrared, visible and UV. -> huge emitter -> more blue light -> oh no

Plants green cause absorb light except green light -> green light reflect to your eye -> plant is green -> very very little blue light -> all good

E-ink tablets -> emit very little blue light-> no eye strain -> no pain

But why blue light bad?
Blue light -> high frequency than other lights -> more energy -> bad.
Similar to UV, xray and gamma, except they’re ionizing radiations.
