It's been happening to me all day long though.
Hmm, maybe you should get it checked out.
"The most common things that make the muscles in your eyelid twitch are fatigue, stress, and caffeine. Once spasms begin, they may continue off and on for a few days. Then, they disappear. Most people experience this type of eyelid twitch on occasion and find it very annoying. In most cases, you won't even notice when the twitch has stopped.
More severe contractions, where the eyelid completely closes, are possible. These can be caused by irritation of the surface of the eye (cornea) or the membranes lining the eyelids (conjunctiva).
Sometimes, the reason your eyelid is twitching cannot be identified. This form of eyelid twitching lasts much longer, is often very uncomfortable, and can also cause your eyelids to close completely. This type of eyelid twitching is called benign essential blepharospasm.
You should call your primary care physician or eye doctor if:
Your eyelid twitching does not go away within one week. The twitching involves other parts of your face. You have redness, swelling, or a discharge from your eye. The twitching completely closes your eyelid. Your upper eyelid is drooping.
Get more sleep. Drink less caffeine. Lubricate your eyes with eye drops"
