Computer Vision Syndrome

Digital Eye Strain

If you frequently use a computer, there’s a good chance you’ve experienced computer vision syndrome (CVS). CVS, also referred to as digital eye strain, describes a group of eye-and vision-related problems such as, eye fatigue, dry eyes, blurred vision, double vision and headaches, that result from prolonged use of digital screens i.e. computer, tablet, mobile phones and other digital devices.

When you look at a digital screen, your eyes need to work harder to focus. That’s because the text on digital screens isn’t as sharp as the words on a printed page. Also, digital screens are prone to having glare, making it even harder for your eyes to focus properly.

If you are experiencing CVS it does not mean you need to give up your screen time. Changing the way you view a digital screen and also limiting the amount of time you spend in front of a screen will automatically lessen the effect and damage to your eyes.


Ways to Ease Computer Vision Syndrome

Adjust your computer and your posture

Position your computer screen 20 to 28 inches from your eyes (or arms length) and slightly below eye level, about 4 to 5 inches. Tilt the top of the screen back about 10 to 20 degrees. Sitting too close or hunched on a digital screen can increase your risk of eye strain.

Blink Frequently

Blinking helps prevent your eyes from drying out by spreading moisture and mucus across your eyes. Looking at a computer or digital screen may cause you to blink less often than you should. You can also use eye drops designed to keep your eyes moisturised.

Dim your Screen and Reduce Glare

Try dimming your screen if it’s much brighter than the rest of the light in the area. You could also adjust the room lighting to reduce screen glare which happens when light is reflected off your screen.

Use the right eyeglasses

Wearing the wrong prescription can make it difficult for your eyes to focus correctly and this can increase your risk for eye strain and headaches. You may need a prescription just for viewing digital screens.

Take regular breaks

A major cause of CVS is continuous use of a digital screen. To reduce this risk, try taking routine breaks e.g. follow 20-20-20 rule (look at something 20 feet away, for 20 seconds every 20 minutes and rest your eyes for 15 minutes after 2 hours of continuous screen time.
