In cases where both eyes begin to twitch or a person suffers from chronic twitching that does not resolve itself, Healthline explains that a person may be suffering from benign essential blepharospasm. Eye twitching is most often not a health concern, but in rare cases, it can signal that a person is experiencing an underlying nerve or brain affliction. Parkinson's disease, Bell's palsy, dystonia and Tourette syndrome may cause uncontrollable eye twitching. Healthline advises people with chronic twitching in one or both eyes to visit a healthcare professional to assess additional symptoms and determine a cause or treatment plan.
