why is it unhealthy to stare at phones for long periods of time (like on social media) but healthy to read books?
In: Technology
Staring at screens is unhealthy for many reasons, it can cause eye fatigue and headaches due to the flickering and blue light emitted by screens, that books do not.
A screen to you looks flacid and constant, but infact if you take a slow motion camera it is actually constantly flickering and emitting “blue” light which is highly fatiguing on the eyes.
Books do not do this at all, as they are, well not screens.
This is why blue light lense glasses are excellent for office workers especially, it blocks out the Blue light and can deter headaches and eye strain.
