TOP TIPS FORHEALTHY SCREEN TIME
The amount of time you spend staring at a computer screen affects your eyes and can make symptoms of dry eye worse. According to various scientific studies, most of us blink less frequently (up to 66% less) when we’re concentrating or staring at a screen.
Blinking is important because it spreads your tears across the surface of your eyes creating a protective film (‘tear film’). If you blink less, this tear film evaporates, drying out your eyes.
The brightness of your screen also contributes to dryness and tired eyes. The brighter your screen, the more you may find that you’re squinting at the screen (especially towards the end of the day).
“The 20-20-20 rule. Look away from your screen every 20 minutes, at something 20 feet away, for 20 seconds - this helps to reduce eye strain.”

Digital Eye Strain, also referred to as Computer Vision Syndrome or CVS, describes vision-related problems that result from prolonged computer, tablet or smartphone use.
There's no definitive proof that digital screen use causes any long-term damage to the eyes. But regular use can lead to general discomfort.
