Again the intensity of twitching varies from one person to another. For some there can be spasms throughout the day and for some others they get it only when they are tensed or emotional. In rare cases, twitching of eyelids can be chronic leading to constant winking of eyelids. It will cause difficulty in opening the eyes.


Causes :

In case of severe contractions the eyelids will completely close. And there can be irritation on the cornea or outer membrane/lining of eyelids. Exact reason for eyelid twitching is unknown. It can be due to lack of sleep or underlying eye infection. For some people it can be due to eyelid infection like blepharitis or dry eyes. It can also be caused due to photo sensitivity. It can be caused due to the side effects of prolonged use of drugs for epilepsy or psychosis.


Symptoms :


Eyelid twitching can be repeated and creating spasms of the eyelids. The person can experience difficulty in opening the eyes when it twitches uncontrollably. It can cause blurry vision and the eyes can become sensitive to light. In rare cases, it can be an indication of nerve disorder like Bell’s palsy, Parkinson’s disease and Dystonia.


Diagnoses :

Treatment :


No treatment is necessary for casual eyelid twitching since it will disappear after some days. In case if twitching is accompanied by irritation of eyes or lining called conjunctiva you can manage it with over the counter artificial tears.
