Screens are now part of everyday life from schoolwork and office tasks to social media and streaming. But increased screen time has led to a growing problem: digital eye strain.

Also known as computer vision syndrome, digital eye strain occurs when the eyes become fatigued from prolonged use of digital devices such as computers, tablets, and smartphones.

Why Do Screens Strain Our Eyes?

Unlike printed text, digital screens:

Have glare and reflections

Require constant focusing and refocusing

Reduce blink rate (we blink up to 50% less when using screens)

Often encourage poor posture and viewing distances

All of these factors place extra stress on the visual system.

Common Symptoms

Digital eye strain may cause:

Dry, irritated eyes

Blurred vision

Headaches

Eye fatigue

Neck and shoulder pain

Difficulty focusing after screen use

Children may not always verbalize discomfort but may rub their eyes, lose attention, or avoid near tasks.

The Impact on Learning and Productivity

When eyes are tired, concentration drops. Students may struggle to sustain attention during digital learning, and adults may notice decreased efficiency at work. Over time, persistent discomfort can affect overall performance and well-being.

How to Reduce Digital Eye Strain

Simple habits can make a big difference:

Follow the 20-20-20 rule: Every 20 minutes, look 20 feet away for 20 seconds.
Blink more often: Make a conscious effort to fully blink.
Adjust screen position: Keep screens at eye level and about an arm’s length away.
Reduce glare: Use proper lighting and anti-glare screens if needed.
Schedule regular eye exams: Ensure your visual system is functioning efficiently.
