If you frequently use a computer, there’s a good chance you’ve experienced computer vision syndrome. This is a type of eye strain that’s caused by prolonged use of digital screens. Among other symptoms, computer vision syndrome can cause:
•eye fatigue
•dry eyes
•headaches
Experiencing computer vision syndrome doesn’t mean you need to completely give up your screen time, though. The way you view a digital screen can make a big difference.
To learn more about computer vision syndrome, read on. We’ll explore the causes and symptoms of this condition, along with lifestyle changes that may help prevent it.
Computer vision syndrome, also known as digital eye strain or computer eye strain, is a condition that can cause specific vision and eye problems, such as:
•eye strain
•eye fatigue
•headache
•blurry vision
•double vision
1. Adjust your computer
Position your computer screen 20 to 28 inches from your eyes. Sitting too close to a digital screen can increase your risk of eye strain. Place the screen slightly below eye level, about 4 to 5 inches. Tilt the top of the screen back about 10 to 20 degrees. Make sure you’re not tilting your neck upward or downward to see the screen. You can also make the text and images more visible and easier to read by increasing the contrast, brightness, and font size on your device.
2. Blink frequently
Blinking helps prevent your eyes from drying out by spreading moisture and mucus across your eyes. If you don’t blink often enough, it can cause your eyes to become dry and irritated. Looking at a computer or digital screen may cause you to blink less often than you should. In fact, according to the University of Iowa, you blink 66 percent less while on a computer. Try to remember to blink often when using a computer or other digital device, and take regular breaks from your screen to give your eyes a rest.
3. Reduce screen glare
Screen glare happens when light is reflected off your screen. The light often comes from overhead lighting fixtures or nearby windows. Try to reduce or eliminate glare by: •closing blinds, shades, or curtains on windows to reduce or minimize screen glare •using lower wattage light bulbs •dimming overhead lights •adding a screen glare filter to your computer
In many cases, computer vision syndrome may go away or be less of an issue if you reduce your digital screen time. The lifestyle changes mentioned above may also help ease or prevent symptoms.
However, if your symptoms persist or get worse, call or visit an eye doctor. Also contact your eye doctor if you have:
•sudden vision changes
•eye flashes
•unexplained eye pain or redness that doesn’t go away
•dry eyes that don’t get better with eye drops
Computer vision syndrome commonly affects people who use digital screens for long periods of time. It can cause a range of symptoms, including:
•eye fatigue
•headaches
•dry eyes
•blurry vision
To prevent digital eye strain, rest your eyes for 15 minutes after using the computer for 2 hours. Adjust your screen and workspace to reduce glare. Blink often and use lubricating eye drops to moisturize your eyes.
