What is digital eye strain?
It’s the visual fatigue that appears after prolonged use of electronic devices such as a computer, smartphone, or tablet. It’s associated with symptoms like blurry vision, dry eyes, headaches, or difficulty concentrating.
Why does it occur?
Continuous screen use reduces blinking frequency, which causes dryness and fatigue. Poor lighting and incorrect posture are also contributing factors.
What does the latest science say?
A 2022 review recommends limiting screen time to less than 4 hours a day whenever possible, taking breaks every 20 minutes (the 20-20-20 rule), optimizing workspace ergonomics, and spending time outdoors. The Mayo Clinic (2024) suggests using artificial tears even if there’s no discomfort, and adjusting screen brightness and contrast.
How can I prevent it?
Follow the 20-20-20 rule: every 20 minutes, look at something 6 meters (20 feet) away for 20 seconds. Maintaining good posture, use artificial tears, adjust ambient lighting and rest your eyes with off-screen activities.
Summary
Digital eye strain can be prevented with simple, evidence-based habits: regular breaks, ergonomic, adjustments, eye lubrication, and balancing screen use with outdoor activities.
