Question

For about a week now I have had twitching in both of my eyes. I can't tell if it's from the eye or the eyelid. What is wrong with me? It's embarrassing. They aren't closing, they're just twitching.

Answer

Eyelid twitching can have many causes. Some of these causes can be indicators of a serious problem, but the majority of cases are not serious. The list of common possible causes of one-sided twitching includes: fatigue, lack of sleep, habit (a nervous tic), and local irritation of the cornea or conjunctiva (misdirected eyelash or dryness).
 

If the movements involve both eyes, and are more like squeezing rather than blinking, there's the possibility that you have blephorospasm. This condition is chronic, more common in women over 50, and can progress into repeated forceful closing of the eyes. The eyes remain quite healthy. There's no definite cause, but it's worsened by stress, bright lights, too much TV, and fatigue. It can be helped enormously by Botox (botulinum toxin) injections into the muscles around the eye, but this needs to be repeated every 3 to 4 months. Less severe cases can be treated by drugs, dry eye treatment, and stress management techniques.
