Digital Eye Strain: Simple Screen Habits That Help

What Is Digital Eye Strain?

Digital eye strain — sometimes called computer vision syndrome — is a group of eye and vision problems caused by long hours in front of screens. When we look at a screen, our eyes focus, refocus and move constantly, and we blink far less than we should. The result is tired, dry, burning eyes and even headaches by the end of the day.

The 20-20-20 Rule

The simplest habit that works: every 20 minutes, look at something 20 feet (about 6 metres) away for 20 seconds. This gives your focusing muscles a genuine rest and encourages blinking.

• Set a gentle timer or use a "break reminder" app
• Look out of the window — distance gazing is the goal
• Stand and stretch; it helps your eyes and your posture

Set Up Your Screen the Right Way

• Distance: keep screens roughly an arm's length away
• Position: top of the screen at or just below eye level
• Brightness: screen should match your room's lighting — not glaring, not dim
• Blink: make a point of blinking fully and often
• Angle: reduce glare by avoiding bright lights behind or beside the screen

When Eye Strain Persists

If your eyes stay sore, dry or blurry despite good habits, it may not be "just screen time". An uncorrected prescription — even a mild one — makes eye strain worse. Persistent symptoms like these are worth a proper eye examination.

Quick Wins for the Whole Family

• Use the 20-20-20 rule during homework and gaming too

• Keep screens out of the hour before bedtime — it helps you sleep, and your eyes rest
