Does the eye twitch annoy you?
An eye twitch or myokymia is repetitive involuntary spasms of eyelid muscles that occurs for a few seconds, for a minute or two. It can occur in upper lids as well as in lower lids. It can be unpredictable and may last for several days or even longer. It does not hurt but it may be irritating. It is usually painless and harmless. It is rarely a sign of anything serious. It usually goes away on its own. However, if the eye twitching lasts for a long period of time or does not go away within a few weeks, it is recommended to see an ophthalmologist make sure nothing serious is going on.
Common causes of eye twitching are stress and fatigue. Other causes are eye strain, eye irritation, eyes that need glasses, consumption of alcohol, tobacco, and caffeine, side effects of medications, dry eyes, nutritional deficiencies, and allergies.
