We’ve all been there. Out of nowhere, your eye starts twitching. Sometimes it’s the top lid, sometimes the bottom. Sometimes it leaves as quickly as it arrived. Other times, it stays for days or longer. So what’s going on? John A. Moran Eye Center neuro-ophthalmologist Srav Vegunta, MD, offers some answers to common questions about this global experience:
How do I know if I have an eye twitch?
Your upper or lower eyelid muscles will contract or cause small involuntary spasms or blinks. Although the contraction is mild, it may feel more noticeable than it actually is. People probably won’t see it at all when they look at you.
What can cause or worsen an eye twitch?
Although we are not 100% sure, it may come from the motor nerves of the brain. We usually look at a number of causes, including lack of sleep, stress, eye strain, light sensitivity and dry or irritated eyes. Too much caffeine and certain medications can also contribute to twitching. In some cases, it runs in families.
How long do eye twitches usually last?
In most cases, it’s temporary, goes away on its own, and doesn’t affect your vision.
What can I do to make eye twitching go away?
Get quality, restful sleep. Limit caffeine intake, whether from coffee, tea or soft drinks. Try to reduce stress with exercise, deep breathing, medication, or taking a restful break from stressful situations. Keep your eyes hydrated with soothing eye drops.
When should I see a doctor for an eye twitch?
In more severe cases, the eyelids may close forcefully, last for seconds or minutes, and become more noticeable over time. If this happens, it is necessary to consult a doctor to rule out other conditions. Some people experience neurological problems, such as blepharospasm or hemifacial spasms, which can cause the eyelid muscles to contract. Generally, these conditions cause the eyelids to close completely and for more extended periods. They can limit or block vision. Spasm of the hemifacial may cause contractions of other muscles in the face. If the contractions last for weeks or you have trouble opening the eye or seeing, contact your doctor. You may benefit from oral medications or a series of botulinum toxin injections. When injected under the skin around the eyes, botulinum toxin can relax the muscles and prevent spasms for a few months.
