I know that stress, and being tired can cause your eye to twitch, but, why?

I don’t know about those two things. Usually caffeine is the culprit for eye twitching in my experience.

I am wondering about the connection, though. :)

“While we’re all under stress at times, our bodies react in different ways. Eye twitching can be one sign of stress, especially when it is related to vision problems such as eye strain (see below). Reducing the cause of the stress can help make the twitching stop.

Vision-related stress can occur if, for instance, you need glasses or a change of glasses. Your eyes may be working too hard, triggering eyelid twitching.

Computer eye strain from overuse of computers, tablets and smartphones is also a very common cause of vision-related stress.”

I do need glasses, and probably sitting at the computer (studying for a good 6 hours) is playing my eyes. Makes sense.

I know what you’re asking. You want to know the connection between what I call eyestrain and eye twitching but I don’t know. Something to do with using the eye muscles/muscle too much.

Good question. I’ve had a really annoying tic that comes and goes, but always the same eye and same place near my eye, for over two months now.

Well, because you’re tired and need to sleep! Your body is telling you to go to bed! :)
