What are the possible causes of eye twitching?

Eye twitching, or myokymia, is the involuntary, repetitive spasm of the eyelid muscles. Common causes include:

Stress and fatigue: Lack of sleep or high stress levels often trigger twitching. Eye strain: Long hours looking at screens or needing vision correction can cause eye muscle fatigue. Caffeine or alcohol: Excess intake may lead to muscle spasms. Dry eyes: Insufficient tear production or irritation can trigger twitching. Nutritional imbalances: Deficiencies in magnesium or other nutrients may contribute. Allergies: Eye irritation from allergies can cause twitching.

Rarely, persistent twitching could be related to neurological disorders. If twitching lasts longer than a few weeks or is accompanied by other symptoms like facial spasms or vision changes, see a healthcare provider.
