6 Common Causes of Eyelid Twitching

Twitching, also known as blepharospasm, is a repetitive and uncontrollable spasm of the eyelid. Most people will develop this minor, irritating twitch at some point in their lives. Eyelid twitching is usually harmless and resolves on its own without medical treatment. Read our following guide to learn the 6 most common causes of eyelid twitching.


Everyone reacts differently to stress. A twitching eyelid can be a sign that the body is stressed. Reducing stress is key to stopping this type of eyelid twitching.


A lack of sleep can trigger the eyelid to begin twitching. Whether you are tired from stress or work, catching up on sleep can help resolve this problem.

Eye Strain

Overuse, computer screens, or an outdated eyeglass prescription can all result in eye strain. If eyelid twitching becomes persistent, it may be time to update your prescription or get special computer glasses.

Caffeine and Alcohol

Many experts believe that excess amounts of caffeine and/or alcohol can cause eyelid twitching. If your caffeine or alcohol levels have recently increased, consider cutting back.

Dry Eyes

Dry eyes can be caused by aging, certain medications, computer use, contact lenses, and excess amounts of caffeine and alcohol. This condition can also cause eyelid twitching. Consult your optometrist for dry eye treatments.


Many people with seasonal allergies experience watery eyes, swelling, and eyelid spasms. Recent studies have shown that histamine may trigger eyelid twitching. The use of eye drops and antihistamines may help correct this problem.
