Computer Vision Syndrome

Computer Vision Syndrome is an increasingly common condition as digital devices become more ingrained into our daily lives. Computer vision syndrome (CVS) results from extended exposure to digital screens such as computers, smartphones, tablets, and televisions. 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, contribute to the effect these devices have on our eyes.

Symptoms of computer or digital eye strain 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. However, our Boise eye doctors have several tips to help you reduce the damage done to your eyes by blue light.

Tips To Alleviate Digital Eye Strain:

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. 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.
