Eye spasm or twitch usually occurs in the upper lid, but can occur in both the upper and lower lid. These movements are unpredictable, painless, harmless, does not affect vision and resolves on its own but it bothers the patient. Mostly, these spasms are very mild and feel like a gentle tug on the eyelid. However, there are some neurological problems that can make eyelid muscles contracts, such as blepharospasm and hemifacial spasm. These less common conditions generally tend to cause the eyelids to close more fully and for longer periods of time, limiting or completely blocking vision. Another condition known as hemifacial spasm exists, wherein an involuntary twitching on one whole side of the face occurs, caused by compression of one of the facial nerve.Other muscles in the face may be affected as well.
Eyelid twitching may be triggered by:
- Alcohol intake
- Bright light
- Caffeine excess
- Irritation of the eye surface or inner eyelids
- Lack of sleep
- Physical exertion
Other conditions that sometimes include eyelid twitching as a sign include
- Corneal abrasion
- Dry eyes
- Light sensitivity
- Bells palsy
- Cervical dystonia
- Multiple sclerosis
- Oromandibular dystonia and facial dystonia
- Tourette syndrome
For the majority, the common eyelid twitch is a brief and minor irritant. But when it lasts longer or occurs more frequently than usual, there are some tips to reduce the effect.
1. Get some rest
2. Reduce stress
3. Drink less caffeine
4. Moisturize the eyes
Usually, no treatment is required for such tics but one needs to see the ophthalmologist if following events occur.
2. Eyelids get drooped.
3. Eyelid gets completely closed with each twitch or there is difficulty opening the eye.
4. Continues for several weeks.
5. Involves other parts of a face.
