Most of us know the feeling: a twitch in the eye, uncontrolled and unintentional. It can be distracting, irritating, and a little uncomfortable.
An eye twitch can be annoying, but have you ever grown concerned that it might indicate something more serious? A sign of eye disease or another problem in the body, perhaps? There’s no need to rush to worst-case scenarios—there’s a range of causes for eye twitching, many of them mild and manageable.
The professionals at EyeRx are here to help you understand anything that affects your eyes and your vision. Read on to explore what causes eye twitching, how twitching can be mitigated, and when it’s time to bring your concerns to the optometrist.
Types of Twitches
There are different types of eye twitches, and their severity varies:
- Myokymia: involuntary spasms of the eyelid. These are generally mild, like a gentle tug on the eyelid.
- Blepharospasm: a chronic eye twitch that may begin with small spasms, but develops into eyelid twitches that can force your eye closed.
- Hemifacial spasm: muscle spasms that affect one side of the face, including the eyelid. This may be caused by an injury, tumor, or an artery pressing on a nerve.
These eye twitches can happen with different levels of severity and may be connected to other systemic conditions and eye problems.
Causes of Eye Twitching
Eye twitching can occur sporadically, seemingly without warning. Let’s break down what can lead to muscle spasms in the eyelid and surrounding areas.
The Mundane & Easily Treatable
The majority of eye twitching is completely harmless. Many cases of eye twitching can be linked to interruptions in a healthy lifestyle. Factors include:
- Lack of sleep
- Excessive caffeine consumption
- Too much alcohol
- Exposure to too much light
- Too much exercise
More Concerning Causes
In a small number of cases, eye twitching is a symptom of a more serious underlying problem. These include disorders like:
- Bell’s palsy: temporary weakness or paralysis of the face muscles.
- Dystonia: Involuntary muscle contractions that can affect multiple parts of the body
- Multiple sclerosis (MS): a central nervous system disorder where your immune system attacks the protective layer around your nerves
- Tourette’s syndrome: a neurological disorder that’s characterized by tics from muscle spasms to vocal tics
- Parkinson’s disease: a neurological condition that worsens over time & impacts movement
- Myasthenia gravis: a neuromuscular condition that may be linked to the autoimmune system that results in the weakening of muscles, including spasms
How Eye Twitching Can Affect Your Vision
Though most eye twitching passes quickly and isn’t concerning, a chronic eye twitch may interfere with clear vision and your day-to-day life. Watch for vision problems associated with the eye twitching, like:
- Eye irritation
- The sensation there’s something in your eye
- Increased rate of blinking
- Light sensitivity
- Dry eyes
- Blurred vision
- Double vision
- Facial spasms (such as the eye closing of its own accord)
Eye twitching can also have a close relationship with other eye conditions, exacerbating their symptoms.
When to Visit the Eye Doctor
We encourage you to talk to your optometrist whenever you have a new symptom arise in your eyes. Note any changes in your vision and bring them to your eye doctor’s attention as soon as possible. Prevention is the best medicine, and routine eye exams can help diagnose problems before they become too serious.
If you’ve tried to get more sleep, reduce stress, cut back on caffeine and alcohol, yet still have a prevalent, uncontrollable eye twitch, it’s likely time to see the doctor. Other signs its time for medical intervention include:
- Eye twitching that’s gone of for weeks
- Complete closure of the eye during a twitch
- Difficulty opening the affected eye
- Twitching in multiple areas of the body
- An eye that’s red, swollen, or has discharge
- Droopy eyelids
