Screen Time and Eye Strain: What You Need to Know in 2026

What Causes Digital Eye Strain?

Screens cause more eye fatigue than printed text for several reasons. Digital text is less sharp and has lower contrast. We blink up to 66% less when staring at screens, causing dryness. Our eyes constantly refocus as we shift between screen elements. Blue light from screens may also disrupt natural sleep cycles and cause additional eye discomfort.

Common Symptoms to Watch For

• Blurred or double vision after extended screen use
• Dry, red, or irritated eyes
• Headaches, especially around the forehead and temples
• Neck, shoulder, or back pain from poor posture
• Difficulty focusing on distant objects after screen time
• Increased sensitivity to light

The 20-20-20 Rule

Ophthalmologists recommend the 20-20-20 rule as a simple starting point: every 20 minutes, look at something 20 feet away for at least 20 seconds. This relaxes the focusing muscles in your eyes and gives them a brief recovery period.

Other Practical Tips

• Adjust your screen brightness to match your environment
• Position your monitor about an arm's length away and slightly below eye level
• Use night mode or warm colour settings on your devices in the evening
• Consider artificial tears if your eyes feel dry throughout the day
• Ask us about blue light filtering lenses during your next visit

When to See an Ophthalmologist

If symptoms persist even after adjusting your habits, it's time to come in. You may have an underlying refractive error (like astigmatism or presbyopia) that's being aggravated by screen use. Dr. Mickey's can assess your full visual health and recommend the right lenses or treatments.
