What is Eye Twitch?
An eye twitch is an uncontrollable spasm of the eyelid muscles. A twitch occurs in both the upper and lower lids but usually occurs in the upper lid. This abnormal blinking may happen many times per day. If the eye twitching persists for days or longer, it can affect your vision. Although, these spasms are very mild and feel like a gentle tug on the eyelid. The spasm can be strong enough to force both eyelids to close completely. This stage of the condition is called (blepharospasm).
