Protecting Your Eyes from Digital Eye Strain

From morning alarms to late-night scrolling, most of us spend 8–12 hours a day looking at screens. The result for many is digital eye strain — tired, dry, aching eyes, blurred vision and headaches by the end of the day.

What causes digital eye strain?

When we concentrate on screens, we blink far less often — up to 60% less — so the tear film dries out. Add reduced contrast, glare, small text and long focusing distance, and the eye muscles stay contracted for hours.

Symptoms to watch for

• Dry, gritty or burning eyes
• Blurred or double vision
• Headaches around the eyes and forehead
• Neck and shoulder pain
• Difficulty focusing when switching between screen and distance

The 20-20-20 rule

Every 20 minutes, look at something 20 feet (about 6 metres) away for 20 seconds. This simple habit relaxes the focusing muscles and gives your blink rate a chance to recover.

Digital eye strain does not cause permanent damage, but ignoring it makes every working day uncomfortable — and it is almost entirely preventable.

Practical protection tips

1. Adjust your setup: keep the screen 50–70 cm away, with the top of the monitor slightly below eye level.
2. Reduce glare: position screens away from windows and use a matte screen filter.
3. Increase text size: if you lean in to read, your font is too small.
4. Blink consciously: full blinks keep the tear film even.
5. Use artificial tears: preservative-free lubricating drops relieve dryness.
6. Consider computer glasses: anti-glare or blue-light filtered lenses reduce fatigue for heavy users.

When to get checked

If symptoms persist despite these habits, book an eye examination. Uncorrected small prescriptions, astigmatism or dry eye disease often hide behind "screen fatigue", and correcting them makes an immediate difference.

Your eyes are your most important work tool — give them the same care you give your devices.
