Have you ever wondered why all of the sudden your eye twitches without any warning?
Also called eye spasms, eyelid twitching could be a little annoying and are caused by the small muscles and nerves around the eye. Just as you may experience an involuntary muscle spasm in your elbow or knee, you can also experience it in the eyelid. The good news is that it’s a common occurrence. We can all rest easy knowing there usually isn’t anything too serious going on.
The twitch may happen in one or both eyes and can occur spontaneously and uncontrollably. While some twitching will only last for a few seconds, there are cases that it can continue off and on for several days.
When that happens it could possibly be an eye disease.
Things That Make Eyelids Twitch
Eye doctors are not sure what causes eyelids to twitch, but they believe it may often be related to stress and fatigue. In some cases, the cause of a twitching eye condition may never be identified.
While we're all under stress at times, our bodies react in different ways. A twitching eye can be one sign of stress, especially when it is related to vision problems such as eye strain (see below). Reducing the cause of the stress can help make the twitching stop.
A lack of sleep, whether because of stress or some other reason, can trigger a twitching eyelid. Catching up on your sleep can help.
3. Eye strain
Vision-related stress can occur if, for instance, you need glasses or a change of glasses. Your eyes may be working too hard, triggering eyelid twitching. If your eyelid twitching is persistent and very annoying, you should have an eye exam, because you may need vision correction.
4. Caffeine and alcohol
Many experts believe that too much caffeine and/or alcohol can trigger eye twitching. If your caffeine (coffee, tea, soda pop, etc.) and/or alcohol intake has increased, cutting back is worth a try.
5. Dry eyes
More than half of the older population experiences dry eyes, due to aging. Dry eyes also are very common for people who use computers, take certain medications (antihistamines, antidepressants, etc.), wear contact lenses and consume caffeine and/or alcohol. If you are tired and under stress, you also may develop dry eye.It's best to see your eye doctor for a dry eye evaluation.
6. Nutritional imbalances
Some reports indicate a lack of certain nutritional substances, such as magnesium, can trigger eyelid spasms. Although these reports lack scientific evidence, I can't rule this out as a possible cause of a twitching eye.
People with eye allergies can have itching, swelling and watery eyes. When eyes are rubbed, this releases histamine into the lid tissues and the tears. This is significant, because some evidence indicates that histamine can cause eyelid twitching.
If your eyelid twitch does not go away in a week, or if symptoms become worse or you are bothered by the twitch, you should be evaluated by an eye doctor. Your doctor will perform a comprehensive eye exam to rule out eye diseases and conditions such as dry eye.
