Eye Twitching, also known as blepharospasm, is the involuntary tic or twitch of an eyelid. It is usually a result of an eye muscle spasm which is caused when the muscle is in a state of stress or excitement. It is the body telling you that the muscles are tired or stressed by causing abnormal blinking or twitching of the eyelids. You feel your eye twitch when there is an uncontrolled contraction of the muscles around the eyelids. Fatigue can easily cause your eye to twitch to tell you that it needs some rest.

These twitches are usually not a serious problem; however they can also occur due to abnormal function of the basal ganglion. Some severe diseases are believed to be the reason behind such abnormalities in the basal ganglion functioning. Therefore, these twitches can also be symptoms of medical conditions such as Parkinson’s disease, autism, or an injury to the cornea. The first thing you should try to stop you’re the twitching is to relax and give your eye some rest.

How Does it Feel?

 An eye twitch feels like a muscle spasm which usually occurs in the eyelids, though sometimes, people may also experience twitching underneath the eye. It usually feels like a blinking disorder and can affect either of the eyes. It starts with abnormal blinking usually accompanied by eye irritation due to the exposure to bright lights, fatigue or stress. The eye twitch usually resolves during sleep and doesn't occur again until several hours later i.e. even after waking up. But, the spasms can become stronger and may even result in the eyelids being tightly shut for long disabling the person from seeing anything. Minor eye twitches usually don't worsen, but if they persist, it is wise to consult an eye care professional.

While blepharospasm like BEB feels like a normal tic, other types of blepharospasm may be associated with dry eyes, neurological problems or other serious problems. In general, people experiencing eye twitching have normal eyes and the vision is also not affected. If there is any disturbance in the vision, it is usually due to the forced closure of the eyelids.

What Makes the Eye Twitch?

Twitching is believed to be caused due to abnormal functioning of certain nerves which might be caused due to fatigue or stress. Such nerve areas control the coordination of muscle movements which may lead to tics or twitches when the coordination breaks. Researchers have also found dryness in the eyes to be a possible reason for the twitching. It can also be caused as a side-effect of some medications.

Diagnosing and Treatment

The diagnosis of eye twitch relies upon how often the twitch occurs and how long it lasts. The family medical history also plays an important role as the eye twitch, although rare, can be inherited from parents.

If you are experiencing a twitching eye for quite some time now, it is best to contact an eye care professional for proper diagnosis and treatment. The eye doctor will treat a prolonged twitch with drug therapy, surgery, and supportive or preventative therapy. Usually, the twitches go away soon.
