Computer Vision Syndrome

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 Doctor Ratinoff at University Optometry today to schedule an eye exam.

Q & A

Frequently Asked Questions with Dr. Dennis E. Ratinoff, OD

Q: What is dry eye syndrome?

  • A: 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.

Q: How can I relieve eye strain after prolonged screen time?

  • A: 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.

5 Ways to Protect and Improve Your Child’s Eyesight

Your child’s vision is their primary window into the world around them. Keeping their eyesight healthy is an important part of allowing them to experience life to the fullest.

Here are 5 tips on how to protect and improve your child’s eye health:

1. Take them to the eye doctor for routine eye exams

One of the most important take-aways from any article you read on the subject of keeping your child’s vision and eyes healthy, is the need to keep up with routine comprehensive eye exams.

Although your kid’s school may perform vision screenings, these tests can only detect the most basic issues, such as myopia (nearsightedness) or severe amblyopia. They are not equipped to check for eye diseases that can affect your child’s long-term ocular health, or binocular vision disorders that can hinder their ability to learn.

Our Palo Alto eye doctor will be able to perform a comprehensive eye exam to check for the presence of these and other conditions. If ocular diseases or vision disorders are detected, your eye doctor will have the equipment and expertise to properly treat them.

2. Limit their screen time

Digital screens are an ever-present part of our lives. Children can spend hours every day texting, playing video games, watching television, doing schoolwork, and more. It’s all too easy to spend way too much time in front of digital devices that emit blue light, which may contribute to digital eye strain. Symptoms of digital eye strain may include:

  • Tired eyes
  • Blurred vision
  • Dry eyes
  • Headaches
  • Sore eyes

To combat digital eye strain and reduce your child’s exposure to blue light, limit their screen time, when possible, and turn off devices a few hours before bedtime to allow your child to wind down.

3. Encourage them to eat healthy foods and get exercise

As with every part of the body, a healthy lifestyle can go a long way in ensuring the long-term health of your child’s eyes.

Eating foods that are rich in omega-3 fatty acids is a great way to promote eye health. Good sources include fish such as salmon and herring. For vegans and others who don’t eat fish, flax seeds, chia seeds and walnuts are also a great option.

Leafy greens and fruits are also important, as they’re high in vitamins A, C and E, which are all important for the development and maintenance of healthy vision.

Along with a healthy diet, you should encourage your child to get up and exercise. Physical activity is good for the whole body, and that includes the eyes.

Bonus points if you can get your child outside, as sunlight and outdoor play have been shown to slow or even prevent the development of myopia. Just make sure your child wears sunglasses and a sun hat — UV rays have a cumulative effect that could lead to eye diseases like macular degeneration later in life.

4. Help them avoid eye injuries

Eye injuries are an all-too-common occurrence, especially among children.

If you have little ones at home, make sure that paints, cleaners and other dangerous chemicals and irritants are put away somewhere safe. If these ever get into their eyes, they can cause severe damage to your child’s visual system, including permanent loss of vision.

For contact and ball/puck sports, ensure your child wears the right eyewear to protect their eyes from accidental impacts or pokes. Helmets should also be worn where the sport warrants it, to prevent concussions and other head injuries that can have an effect on vision.

5. Reduce eye infections

Even small, common infections such as pink eye can have an impact on your child’s vision.

Hands are some of the most bacteria-filled parts of our bodies. Your child should learn not to touch their eyes with their unwashed hands, as this is the primary way of introducing germs to the eye that may result in infection.

On a similar note, if you have contact lens wearers, be sure to teach them to wash their hands each and every time they put in or take out their contact lenses. They should also learn to store and clean their lenses strictly according to their eye doctor‘s instructions and should change lenses according to their intended schedule. Daily contacts should be changed daily, monthly contacts, monthly.

Q&A

Frequently Asked Questions with Dr. Dennis E. Ratinoff, OD

Q: Can I rely on the vision screenings at my child’s school to catch vision and eye health issues?

  • A: No. School-based vision screenings check for basic visual acuity. Even if your child has perfect 20/20 vision, there may still be issues with visual skills or undetected eye diseases that these types of screenings are not equipped to catch.It is important not to rely on school vision screenings as a replacement for an annual comprehensive eye exam with your local optometrist. During these visits, your eye doctor will be able to assess your child for vision skills such as:Eye teaming ability
    Convergence and divergence skills
    Tracking and focusing Visual accommodation

    They will also be able to diagnose and treat conditions such as:

    Amblyopia
    Strabismus
    (Rarely) pediatric glaucoma or cataracts

    These and other conditions can only be diagnosed and treated by a trained optometrist as part of a comprehensive eye exam.

Q: Can vision problems be misdiagnosed as ADHD/ADD?

  • A: It is unfortunately common for learning-related vision problems to go undetected. These vision problems can often mimic the symptoms of ADD/ADHD, leading to misdiagnosis and mistaken treatment.As many as 1 out of every 4 school-age children suffers from some form of visual dysfunction. If not properly treated, a child may struggle throughout their entire school career, harming their learning and possibly their long-term self-confidence.

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 University Optometry at 650-666-2191 and schedule an eye exam with Doctor Ratinoff.

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.

Optimize your Eyewear

Since regular prescription lenses or glasses may not adequately meet your visual needs for lengthy computer use, you may benefit from wearing computer glasses. These prescription glasses are customized to your needs and also reduce glare and block blue light.

 

You don’t have to live with the discomforts of eye strain. If symptoms persist, it may be time to visit University Optometry and get the relief you seek. Call our office to schedule a convenient eye doctor’s appointment.

 

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 Doctor Ratinoff 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 Palo Alto.

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.

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, University Optometry 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 Doctor Ratinoff 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.

University Optometry 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 University Optometry in Palo Alto to make an appointment with Doctor Ratinoff 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.
