The Digital Dilemma
We live in a screen-first world. Between work, school, entertainment, and staying connected, the average person spends over 7 hours a day looking at digital screens. For many professionals and students in Nepal, that number is even higher.
While technology has made life easier in many ways, our eyes weren't designed for this much close-up, focused screen work. The result is a cluster of symptoms that eye care professionals call digital eye strain, or computer vision syndrome.
What Happens to Your Eyes
When you stare at a screen, several things change:
- Reduced blinking — Your blink rate drops by up to two-thirds, leading to dry, irritated eyes.
- Sustained accommodation — Your focusing muscles stay locked in a near-point position, causing fatigue and headaches.
- Blue light exposure — While the long-term effects are still being studied, high-energy visible light can contribute to discomfort and may affect sleep patterns.
- Poor posture — Hunching over devices creates neck and shoulder tension that compounds visual discomfort.
Recognizing the Signs
Digital eye strain can show up in different ways:
- Tired, heavy-feeling eyes
- Headaches, especially in the forehead or temples
- Blurred vision at near or when switching between distances
- Dry, gritty, or watery eyes
- Neck and shoulder pain
- Difficulty concentrating after prolonged screen use
Practical Solutions That Work
The 20-20-20 Rule
Every 20 minutes, look at something at least 20 feet (6 meters) away for at least 20 seconds. This gives your focusing muscles a break and encourages blinking.
Optimize Your Workspace
Your screen should be about arm's length away and slightly below eye level. Reduce glare by positioning your screen perpendicular to windows, and adjust brightness to match your surroundings.
Conscious Blinking
Train yourself to blink fully and frequently while using screens. Some people find it helpful to place a small reminder note on their monitor.
Blue Light Management
Blue-light filtering glasses can reduce discomfort for some people, especially those who use screens late into the evening. Built-in night mode settings on devices also help by shifting the color temperature to warmer tones.
Regular Eye Exams
An uncorrected or under-corrected prescription makes digital eye strain significantly worse. Even a small refractive error that doesn't bother you during daily activities can cause major discomfort during extended screen use.
When to Seek Professional Help
If your symptoms don't improve with lifestyle changes, or if you're experiencing persistent headaches, blurred vision, or eye pain, it's time for a comprehensive eye evaluation. Sometimes what seems like simple eye strain can be an underlying binocular vision problem or dry eye condition that needs targeted treatment.
