Almost all sudden-onset eyelid twitching is benign, meaning the condition is not serious or a sign of a medical problem.To find a solution for a twitching eye, we first need to determine the underlying cause.Triggers can include:

Stress
Tiredness
Eye strain
Caffeine
Alcohol
Dry eyes
Nutritional imbalances
Allergies
If you spend a lot of time on the computer, you might want to talk to your eye doctor about special computer eyeglasses for example.
Too much caffeine can trigger eye twitching. Try cutting back on coffee, tea, chocolate and soft drinks (or switch to decaffeinated versions) for a week or two and see if your eye twitching disappears.
If you have a twitching eyelid and your eyes feel gritty or dry, see your eye doctor for a dry eye evaluation. Restoring moisture to the surface of your eye may stop the spasm and decrease the risk of twitching in the future.

To offset this problem, some eye doctors have recommended antihistamine eye drops or tablets to help some eyelid twitches. But remember that antihistamines also can cause dry eyes. It's best to work with your eye doctor to make sure you're doing the right thing for your eyes.
