Why Is My Eyelid Twitching?

What Is An Eyelid Twitch?

Myokymia, more commonly known as an eyelid twitch, occurs when the eyelid muscles spasm uncontrollably. This sensation is generally felt in either the upper or lower eyelid of one eye.

An eyelid twitch can develop for a number of reasons, and can last anywhere from a few moments to several days, depending on the underlying cause.

Eyelid twitches are usually nothing to worry about, though persistent eyelid spasms can signal a more serious underlying condition.

What Causes Eyelid Twitching?

There are a range of factors that could be causing your eyelid to twitch, including:

Stress.

This is the most common cause. Any type of physical or mental stress leads to the release of cortisol, a steroid hormone in the body that acts as a stimulant and puts your body into “flight or fight” mode. It can affect the nervous system in uncharacteristic ways, including making the nerves stimulate your muscles to twitch.

Fatigue.

Have you stayed awake later than usual, or are you juggling work and family commitments? Your eyelid twitch may be a sign that your body is craving a few more hours of rest and shut eye.

Allergies.

Itchy, watery, irritated eyes can cause eyelid spasms.

Dry eyes.

Dry, sore eyes may sometimes lead to an eyelid twitch.

Eye strain.

Eye muscle fatigue from prolonged reading or using a digital device can lead to blurry or double vision, dry eyes, headaches and, sometimes, an eyelid twitch.

Caffeine.

Consuming too much caffeine can over-stimulate your mind and body, including the muscles in your eyes.

Alcohol.

Similar to caffeine, excessive alcohol intake can have stimulating effects on your eye muscles.

Nutrient deficiencies.

According to research, a deficiency in vitamins B12 or D, or magnesium, or other electrolyte imbalance can cause an eyelid twitch.

Blepharospasm.

This rare eye condition is caused by a neurological problem that leads to uncontrollable facial and eyelid spasms that generally worsen over time.These spasms may also cause an increase in blink rate and intensity.

Neurological disease.

Although uncommon, an eyelid twitch can be a symptom of multiple sclerosis (MS), Parkinson’s disease or Bell’s palsy.

How to Stop Your Eye Twitch

Schedule an eye exam to find out what may be causing your eyelid twitch. Your eye doctor may prescribe glasses to relieve eye strain, or recommend dry eye treatments, Botox injections or oral medication to treat the underlying problem.
Practice stress-relieving activities such as yoga and deep breathing exercises, or simply take some time out of your day to relax.
Use eye drops to alleviate eye allergies or dry eye symptoms.
Take frequent breaks from the screen and consider wearing computer glasses to reduce eye strain.
Limit caffeine and alcohol consumption to determine if these stimulants may be the cause of your eyelid twitch.
Speak with your physician to find out if you can benefit from taking nutritional supplements and to rule out a neurological disorder, especially if other symptoms are present.

Although an eye twitch is generally not a cause for concern, if it persists for longer than a few days or you notice any changes to your vision, contact Dr. Pachler at Dr. Robert J. Pachler today to schedule an eye exam.

Q & A

What is dry eye syndrome?

Dry eye syndrome (DES) is a chronic condition that occurs when your eyes don’t produce enough tears or the quality of your tear film is compromised. This results in a range of symptoms that may include dry, itchy, irritated eyes, and sometimes eye twitches. While mild DES can often be alleviated temporarily with over-the-counter lubricating eye drops, moderate to severe DES generally requires specialized in-office treatments.

How can I relieve eye strain after prolonged screen time?

Digital eye strain, also known as computer vision syndrome, can cause a host of uncomfortable symptoms, including headaches, eye fatigue, dry eyes and blurry vision. Computer vision syndrome may cause your eyelid to twitch.

If limiting screen time isn’t practical on a daily basis, try to follow the 20-20-20 rule: every 20 minutes, look at something around 20 feet away for at least 20 seconds. It is also important to remember to blink frequently and to close your eyes completely. Lastly, speak to your optometrist about wearing computer glasses while you work, as they are designed to eliminate glare from the screen, and reduce eye strain.

What Is the Long-Term Impact of Virtual Learning on Children’s Eyes?

Kids, like adults, are spending more time online. At some point during the COVID-19 pandemic, many children attended school via Zoom and completed assignments online. The trend toward more screen time — whether playing games or being in touch with friends — is likely to continue even after everyone returns to the classroom.

We already know that prolonged screen time can cause digital eye strain as well as dry eye symptoms, among other problems in children and adults. There is some indication that extended exposure to blue light may impact the development of retinal cells. However, studies on actual subjects still need to be done to establish a clear connection.

Dry Eyes

Spending a long time in front of screens can impact how quickly our tears evaporate, because we blink around 66% less when using a computer compared to other daily activities. When tears evaporate too quickly and aren’t replenished with blinking our eyes start to feel dry and gritty. So remember to blink every few seconds to prevent your eyes from drying out!

Blue Light Exposure

Screens, such as those that appear on computers, phones and tablets emit blue light. Recent studies have shown that overexposure to blue light can damage the retinal cells at the back of your eyes. This may increase the risk of vision issues such as age-related macular degeneration which eventually leads to permanent loss of vision.

Excess blue light has also been shown to disrupt the circadian rhythms that regulate our sleep patterns, as it tricks your internal clock into thinking that it is the middle of the day. This may lead to difficulty in falling asleep, insomnia, and daytime fatigue.

Digital Eye Strain

Nearly 60% of people who routinely use computers or digital devices experience symptoms of digital eye strain — also called computer vision syndrome. Symptoms of eye strain include eye fatigue and discomfort, dry eye, headaches, blurred vision, neck and shoulder pain, eye twitching, and red eyes.

Taking frequent breaks from your screen can help reduce eye strain and neck, back and shoulder pain during your workday.

It is recommended to take at least one 10-minute break every hour. During these breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to relieve tension and muscle aches.

Also, look away from your computer at least every 20 minutes and gaze at a distant object at least 20 feet away for at least 20 seconds. This relaxes the focusing lens inside the eye to prevent fatigue.

How to Make Virtual Learning Safer For Your Child

The following tips can lessen the impact of screens on your child’s eyes:

Reduce overall screen time
Encourage frequent breaks
Use accessories that filter blue light (for example, blue light glasses)
Schedule regular eye exams

Make Sure Your Child Gets Routine Eye Exams

Children need comprehensive eye exams to assess the health of their eyes, correct their vision and spot potential problems which can affect learning and behavior.

Q&A With Our Eye Doctor in Oakville, Ontario

What are blue light glasses?

Blue light glasses, also known as computer glasses, effectively block the transmission of blue light emitted from devices and computer screens. They often include a coating to reduce glare to further reduce eye strain. These glasses can be purchased with or without a prescription.

What’s the 20-20-20 rule?

If you find yourself gazing at screens all day, whether your computer, smartphone, iPad or television, you’re at risk of experiencing eye strain. So make sure you schedule frequent breaks from your screen and follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. And while you’re at it, use this time to get up, walk around, and stretch.

Four Great Tips to Relax Your Eyes

Do your eyes hurt after spending a significant amount of time reading, playing video games, driving, or staring at a screen? These visually intense activities can sometimes be hard on the eyes, causing uncomfortable symptoms like headaches and blurry vision. Other symptoms of eye strain can include light sensitivity, neck and shoulder pain, trouble concentrating, and burning or itchy eyes.

Fortunately, preventing painful computer vision syndrome and eye fatigue symptoms can be as simple as trying a few of these eye exercises. To learn more about digital eye strain and discover the best relief options for you, call Dr. Robert J. Pachler at 1-833-497-3542 and schedule an eye exam with Dr. Pachler.

Relax Your Eyes with These Supportive Techniques

Many of these exercises are designed for computer users. Eye strain resulting from long drives, reading, or other activities, can be alleviated by modifying some of these recommendations.

The Clock Exercise

The clock exercise relieves strain on overworked eye muscles and can help you avoid headaches and eye pain, among other symptoms. Begin the exercise by imagining a large analog clock a few feet in front of you. Keep your head still and move your eyes to the imaginary 9, then to the imaginary 3.

Keep moving your eyes to the opposite pairs on the clock — 10/4, 11/5, 12/6, and so on. Hold your gaze for a second or two on each number before moving on to the next one. Continue doing this for 4-5 minutes.

The 20-20-20 Rule

The 20-20-20 rule helps you avoid dry eyes and eye strain by giving your eyes frequent breaks. After about 20 minutes of screen time or doing close-up work, focus on an object at least 20 feet away for 20 seconds. This gives the eyes a much needed rest and helps them relax. There are also free apps available that provide pop-up reminders that notify you when it’s time to shift your gaze.

Screen Ergonomics

The American Optometric Association recommends placing computer monitors 20 to 28 inches, or 50-70 cm, away from your eyes and the top of the computer should be at eye level or right below for optimum eye comfort. Glare filters can reduce the amount of glare produced by digital devices and improve your viewing experience.

Poor sitting posture can also contribute to eye strain. Your chair should be situated so that your feet are flat on the floor, or use an angled footrest for additional comfort.

8 Ways to Protect Your Eyes at the Office

Everyone seems to be staring at a screen these days, whether their computer, their smartphone or another digital device. The stress it puts on your eyes can cause a condition called “digital eye strain” (DES) or “computer vision syndrome” (CVS). Symptoms include eye fatigue, dry eyes, blurred vision, headaches, neck and shoulder pain, red eyes, and eye twitching.

How To Protect Your Eyes While You Work

Below are a few things you can do to lower your risk or mitigate any discomfort associated with DES.

1. See your eye doctor for a comprehensive eye exam

This is one of the most important things you can do to prevent or treat symptoms associated with computer vision syndrome. During your eye doctor’s appointment, make sure to speak with Dr. Pachler about your working habits, including the frequency and length of time you use a computer and other devices at work and at home.

If you get a chance before you come, measure the distance between your eyes and your computer screen and bring that information to the optometrist, so that you can get your eyes tested for that specific working distance.

Computer vision syndrome may be exacerbated by an underlying dry eye disease, which can be diagnosed and treated at our eye clinic in Oakville.

Sometimes people who have good visual acuity assume they don’t need any glasses. However, even very mild prescriptions can improve eyestrain and curb fatigue when working at a computer.

2. Good lighting is key

Excessively bright light, whether due to outdoor sunshine coming in through the window or harsh interior lighting, is a common cause of eyestrain. When using your computer, your ambient lighting should be about 50% dimmer than what is typically found in most offices.

You can reduce exterior light by closing drapes, blinds or shades and diminish interior illumination by using fewer or lower intensity bulbs. Computer users often find that turning off overhead fluorescent lights and replacing them with floor lamps is easier on their eyes.

Many eye diseases can be quickly and easily diagnosed during a comprehensive eye exam. If you were diagnosed with an eye disease, such as Cataracts, Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Our Oakville eye doctor has prepared the following answers to your questions about eye disease.

3. Minimize glare

Eyestrain can be aggravated by glare from light reflecting off surfaces including your computer screen. Position your computer so that windows are neither directly in front of nor behind the monitor, but rather to the side of it. Consider installing an anti-glare screen on your display. If you wear glasses, get anti-reflective (AR) coating on your lenses to reduce glare by limiting the amount of light that reflects off the front and back surfaces of your lenses (more on that below.)

4. Upgrade your display

If you have a CRT (cathode) screen on your monitor, consider replacing it with a flat-panel LED (light-emitting diode) screen that includes an anti-reflective surface. Old-school CRT screens can be a major cause of computer eye strain due to the flickering images.

For your new flat panel desktop display, choose one with a diagonal screen size of at least 19 inches, and the higher the resolution, the better.

5. Adjust display settings for added comfort

Adjusting your computer display settings can help decrease eye strain and fatigue too.

Brightness: Adjust your device’s brightness to match the luminance around you. If the white background of this page looks like a light source, then it should be dimmed. However, if it appears dull and gray, it may not provide enough contrast, which can make it hard to read.

Text size: Adjust the text size for maximum eye comfort, particularly when reading, editing or writing long documents. Increase the size if you find yourself squinting, but bigger isn’t always better, since overly large text display may force your eyes to track back and forth too quickly for comfort.

Color temperature: This refers to the spectrum of visible light emitted by a color display. Blue light is short-wavelength visible light, whereas orange and red are longer wavelength hues. Exposure to blue light helps keep you alert but tends to cause eye fatigue after a while; yellow to red tints are more relaxing and may be better for long-term viewing, especially at night. Many devices allow the user to adjust the color temperature.

6. Get computer glasses

Nearly 70% of North Americans experience digital eye strain related to prolonged use of electronic devices. To combat these effects, Dr. Robert J. Pachler recommends digital protection coatings, which act as a shield to cut the glare and filter the blue light emanating from digital screens and artificial light.

For the greatest eye comfort, ask Dr. Pachler for customized computer glasses, which feature mildly tinted lenses that filter out blue light. These can be made with or without prescription vision correction, for the benefit of those with 20/20 vision or contact lens wearers, though many people with contacts actually prefer to have alternative eyewear to use when their lenses become dry and uncomfortable from extended screen time.

Dr. Robert J. Pachler can help you choose from a vast array of effective optical lenses and lens coatings to relieve the effects of digital eye strain.

7. Don’t forget to blink

When staring at a digital device people tend to blink up to 66% less often, and often the blinks performed during computer work are only partial which aren’t as effective at keeping the eyes moist and fresh feeling. Making a conscious effort to blink more while working or watching can prevent dryness and irritation.

8. Exercise your eyes

Another cause of computer eye strain is focusing fatigue. Look away from your computer every 20 minutes and gaze at an object located 20 feet away, for a minimum of 20 seconds. This “”20-20-20 rule”” is a classic exercise to relax the eyes’ focusing muscles and reduce computer vision syndrome.

The steps above don’t require a tremendous amount of time or money to be effective. Contact Dr. Robert J. Pachler in Oakville to make an appointment with Dr. Pachler and learn how the right eye drops, eye exercises, computer glasses, or AR coatings can improve eye comfort, reduce computer vision syndrome and potentially lead to increased productivity and job satisfaction.
