Eyestrain on Digital Devices


2nd February 2021

Tips to relieve digital eyestrain caused by digital device use

Blink more

Staring at a screen for longer periods slows reduces the frequency of blinking which means poorer spread of tears leading to dry & tired eyes

Reduce Glare

 You can tone down the intensity of screen brightness & change the background from white to a dull grey or off white.

 Reduce the surrounding lighting in the room to eliminate light source reflections on the screen.

 Glare reduction screens are available at most office outlets.

 Clean your screen

 Remove smudges & dust to reduce glare & improve contrast.

 Adjust your screen

 Adjust your screen at eye level or just below eye level

 Increase text size to allow for more comfortable scrolling / reading.

 Put a time limit on screen time.

 Consider limiting the amount of time spent on a digital device (easier said than done). Spending just 2 consecutive hours looking at a digital screen can cause eyestrain & fatigue.

 Try the 20-20-20 break

Every 20 minutes, take a 20 second break & look at something 20 feet away.

 Intermediate computer glasses

 Wear computer glasses (intermediate) for longer periods of work solely on the PC, particularly in the case of varifocal wearers, as you don’t have to raise your chin to catch the reading area preventing neck issues developing.

Tinted Lenses

Tinted lenses are another option to help reduce both harsh office lighting & balance colours since they help filter out blue & violet light emitted by many digital devices.
