Not Medical Advice: Eye twitching is a repetitive, uncontrollable blinking or spasm of the eyelid, usually the upper lid. It usually affects the eye muscles of both eyes. If you have eye twitching, you may have an involuntary movement that recurs every several seconds for a minute or two.
Most people develop a minor eyelid twitch at some point in their lives. Although the cause is generally unknown, it may be associated with:
- High caffeine
Sometimes, eye twitching can be a sign of eye conditions such as:
- Blepharitis (inflammation of the eyelids)
- Dry eyes
- Light sensitivity
Very rarely, it can be a sign of a brain or nerve disorder, such as:
- Bell's palsy
- Parkinson's disease
- Tourette's syndrome
