Eye twitching (myokymia) is a rapid, involuntary movement of the eyelid muscles. It may occur mildly or repeatedly enough to become irritating. Twitching can affect either the upper or lower eyelid, on the right or left eye. Although some believe it has symbolic meaning, medically, eye twitching is usually harmless, painless, and temporary. In some cases, however, symptoms may persist and require further evaluation.

Eye twitching on the right or left side is commonly caused by daily lifestyle factors, including:
Although most cases are mild, frequent or severe twitching may indicate underlying conditions, such as:

Ophthalmologists or neurologists may perform a medical history review and physical examination. Additional tests may include:
Botox injections are a medically approved and effective treatment for uncontrolled muscle spasms around the eyes. Botox relaxes the muscles and blocks nerve signals that cause twitching. Results last about 3–6 months, and follow-up treatment may be needed.
Muscle relaxants or sedatives such as lorazepam, trihexyphenidyl, or clonazepam may provide temporary relief. These should be used only under medical supervision due to possible side effects.
Surgery may be considered if symptoms do not improve with Botox or other treatments. This involves cutting the nerves that control eyelid muscles to stop involuntary twitching.
Evaluate your symptoms with our expert ophthalmologists to receive a precise and effective treatment plan.

Summary: Eye twitching is an involuntary eyelid movement commonly caused by stress, lack of rest, or nutrient deficiencies. Persistent or severe symptoms may indicate neurological conditions and should be evaluated by specialists. At Bangkok Eye Hospital, advanced diagnostic tools such as MRI and Botox treatments are available to ensure safe and effective care.
Gently massage around the eyes using circular motions with light pressure to improve blood circulation and relax the muscles. Avoid pressing directly on the eyeballs.
Persistent left eye twitching may be caused by stress, lack of sleep, excessive screen use, caffeine, dry eyes, or magnesium deficiency. If symptoms continue, consult a doctor.
Most cases resolve within a few hours to 2–3 days. If symptoms last longer than one week, medical evaluation is recommended.
