Computer Eyestrain

Digital eye strain is an increasingly common condition as digital devices become more ingrained into our daily lives. Digital eye strain, eye fatigue and computer vision syndrome (CVS) are conditions that result from extended exposure to digital screens such as computers, smartphones, tablets and televisions from a combination of factors including the blue light radiation emitted from the devices and the pixelated content that is difficult for our eyes to focus on.

Symptoms of computer or digital eyestrain tend to be noticed after someone has used a digital device for as little as 2 hours a day. Studies show that 60% of people spend more than 6 hours a day in front of a digital device and 70% of adults report some symptoms of computer vision syndrome (CVS) which include:

  • Eyestrain
  • Headaches
  • Blurred or double vision
  • Physical and mental fatigue
  • Dry or watery eyes
  • Red or irritated eyes
  • Difficulty focusing
  • Sensitivity to light or
  • Neck, shoulder or back pain (caused by compromised posture to adjust to vision difficulty).

Digital eye strain also impacts your ability to focus and lessens productivity. Most people do nothing to ease their discomfort from these symptoms because they are not aware of the cause.

Protecting Your Eyes from Digital Eye Strain and Blue Light

There are a number of options for reducing digital eye strain and your exposure to blue light which include workspace ergonomics, computer glasses, specialized lenses and protective coatings. The first step is to get a comprehensive eye exam, making sure you speak to your eye doctor about how often you use a computer and digital device. This will help your doctor to get the full picture of your eye and vision needs in order to determine which option is best for you. It was also help the doctor to identify any underlying issues that could be worsening your symptoms.

Alleviating Digital EyeStrain

Workspace Alterations

Proper Lighting and Screen Brightness: You want the screen to be as bright as the surrounding environment or the brightest object in the room (depending on what is most comfortable for you). Therefore interior lighting or sunlight from the outdoors should be dimmed or blocked. Use fewer light fixtures or lower voltage light bulbs and close curtains or blinds when possible. Adjust the brightness and contrast of your monitor to the levels that are most comfortable.

Reduce Glare: Glare is a significant cause of computer eyestrain so it is important to minimize it as much as possible. Set up your computer where glare from windows won’t affect your screen or cover windows when this is not possible. Glare can also reflect from walls and shiny finishes on desks and other surfaces. An anti-glare screen on your monitor or an anti-reflective (AR) or anti-glare coating applied to your eyewear can also help to minimize glare and the strain it causes to your vision.

Screen size and distance: You want to make sure you are using a high quality (such as a flat LCD) screen that has a relatively large display (look for a diagonal screen size of at least 19 inches) and is located directly in front of your line of vision. Your viewing distance should be about an arm’s length away with the top of the monitor at about eye level or slightly below.

Eye Care

Keep Eyes Moist: When viewing a digital screen or monitor for an extended period of time, we tend to blink less frequently (about ⅓ as often as we should). Blinking however, is critical for keeping the eyes moist, which allows them to remain clear and comfortable and to avoid dry eyes, irritation, blurry vision or eye fatigue.

Focus on blinking by setting a timer for every 20 minutes and slowly closing and opening your eyes 10 times. Keep a bottle of artificial tears handy to use when your eyes are feeling dry.

Give Your Eyes a Break: Schedule and take frequent breaks from your screen. Follow the 20-20-20 rule; every 20 minutes, look at something 20 feet away for 20 seconds. Take this time to stand up and stretch your back, neck and legs as well.

Computer Eyewear

Computer glasses reduce eye strain by adjusting the focus slightly so your eyes feel like they are focusing on something further away. They also have a tint to remove the glare and block blue light from entering into your eyes. There are a number of options for computer eyewear, both if you need prescription eyewear and not. Speak to your eye doctor about what the best options are for you.

It is important to know that both adults and children alike are susceptible to computer eye strain from computers and digital devices. With the growing use of such devices in our everyday lives it is important to start educating ourselves and our children on how to combat the negative effects of these habits.

Childhood myopia or nearsightedness is a common condition that causes blurred distance vision and can usually be easily corrected with either glasses or contact lenses. Unfortunately, simply getting a pair of glasses doesn’t always solve the problem, because often myopia is progressive which means that every year the vision gets worse. This usually continues until sometime around the child’s 20th birthday when his eyes stop growing and eyesight levels off.

It can be worrisome and quite disconcerting for both the parent and the child when each visit to the eye doctor results in a higher prescription. There could be a number of factors involved in progressive myopia, involving hereditary factors as well as possible environmental or behavioral factors such as frequent close-up tasks such as reading or using an electronic device. In fact, studies show that children that spend more time outdoors playing have a lower incidence of myopia.  Much research is currently being done into treatments for slowing or stopping myopia progression in children.

Here are some of the treatment options currently being offered:

Orthokeratology (Ortho-k)

Ortho-k is a process that uses specially designed rigid gas permeable contact lenses worn at night to gently reshape the cornea, eventually allowing clear vision during the day. The lenses are worn every night or every couple of nights depending on the results of the individual.  Ideal for mild to moderate myopia, ortho-k usually takes a few weeks to show results, during which time the patient may need to temporarily continue wearing glasses or contact lenses.

Studies show that the use of ortho-k can permanently reduce the progressive lengthening of the cornea which is responsible for nearsightedness and can, therefore, slow or stop the childhood progression of the condition.  Therefore, in addition to being used for myopia correction, it is now also being offered as a therapeutic treatment to halt myopia progression in children.

Multifocal Eyeglasses or Contact Lenses

Bifocal or multifocal soft contact lenses or glasses have been shown in some studies to slow myopia progression.  This therapy is based on the idea that the eye is strained from accommodating to see close up and that by providing multiple focusing powers, this allows the eye to relax when doing near work, which reduces the progression of the refractive error. This treatment has been shown to delay or slow the advancement of myopia in some children.

Atropine Drops

Treatment with atropine drops is another therapy that is used to relax the eye from “focusing fatigue” which may be a culprit in myopia progression. Research is still being done but some studies show that daily use of low doses of atropine drops do slow the progression of myopia. Atropine drops dilate the pupil which temporarily prevents the eye from being able to focus, thereby allowing this mechanism to relax. Research is still being done to determine dosages, but the results are promising.

If your child has progressive myopia, seek out a pediatric optometrist who is knowledgeable about the options available. Finding the right treatment could give your child the gift of better eyesight for life.
