Why do electronics (especially phones) hurt your eyes and give you a headache-y after looking at them for a while?
In: Technology
They don’t necessarily. But it may be due to dry eyes or a sensitivity to flickering light that some screens produce (called PWM). It may also be due to having to focus your eyes to a close distance for a long time, which can cause the muscles in your eyes to get tired and strained.
Personally, using eye drops meant for dry eyes helps a lot when I have eye strain, so mine is due to dryness.
