Most eye twitches are involuntary, harmless spasms of the small muscles surrounding the eye. The most common triggers are squinting, stress, fatigue, and excess intake of caffeine and alcohol. Another increasingly common trigger is eye strain, related to long periods of time in front of the computer, working in low light settings or due to a wrong prescription if you wear contact lenses or glasses. Certain medications, especially those used to treat epilepsy or mental health conditions, can also trigger muscle spasms. To see more details visit, www.theglobeandmail.com
