An eye twitch or tremor is a benign, involuntary movement. It can be quite annoying. Technically, this is known as blepharospasm or eyelid fasciculation. It consists of an uncontrollable, sporadic, and repetitive blinking of the orbicularis muscle (the muscle surrounding the eye). It can vary in intensity and typically ceases within a few seconds or minutes.
Nervous tic in the right or left eye
This involuntary twitching of the eyelid—which may cause it to close either partially or completely—may or may not be visible to someone standing in front of you. Such an eye tic can be accompanied by other symptoms, such as sensitivity to light (photosensitivity) or blurred vision. Furthermore, individuals often experience difficulty with tasks like driving, reading, watching television, or engaging in other everyday activities.
In cases of low-intensity eye twitching or a mild pulsation, only a few fibers of the orbicularis muscle are affected. Blepharospasm typically occurs in one eyelid, with the lower eyelid being the more common site for such tremors. Often, when looking in a mirror, you may not be able to see any movement at all, even though you can clearly feel it.
Causes of eye twitches
- Stress:
When we go through periods of stress—whether at work or in our personal lives—our bodies react in different ways; an eye twitch can be one such sign of stress.
- Fatigue or lack of sleep:
A lack of sleep can affect the body in many different ways. Consequently, you may experience episodes of eye twitching if you do not get adequate rest. We recommend having your last meal two to three hours before bedtime. You should also turn off all electronic devices and aim for at least 8 hours of sleep per night.
- Coffee, tobacco, and alcohol:
These three substances have a stimulating effect. They can cause the eye muscles to contract, resulting in an annoying twitch.
- Dry eye syndrome:
It is very important to keep the surface of the eye (the cornea), the eyelids, and the conjunctiva well-hydrated, especially if you are prone to dry eyes. Insomnia and stress can also lead to dry eye.
- Sjögren’s syndrome:
This condition primarily affects women aged 40 and older.
It is characterized by inflammation of the moisture-producing glands in the eyes, which in turn leads to eye twitching.- Poor nutrition:
Certain nutritional deficiencies can also cause eye twitches—for example, a lack of potassium, magnesium, or calcium, which help regulate our nervous and circulatory systems.
- Allergies:
When a person suffers from an allergy, they often experience redness, itching, or watery eyes. We might try to soothe this sensation by rubbing our eyes, which can eventually lead to an eye twitch.
- Tourette syndrome:
Tourette syndrome is associated with various tics, including involuntary vocalizations, such as insults or obscene language.
These symptoms typically appear during childhood. Initially, there may be only a single nervous tic, but over time, many more—of a neurological nature—can develop.
