In an increasingly digital world, health experts are urging people to take better care of their eyes as screen use reaches unprecedented levels. The average adult now spends over six hours a day staring at screens—a number that continues to rise with remote and hybrid work becoming the norm.
The constant exposure to screens is putting significant strain on the eyes, contributing to what medical professionals call Computer Vision Syndrome (CVS). Symptoms range from dryness and irritation to blurred vision, headaches, and fatigue.
Dr. Shahina Pardhan, director of the Vision and Eye Research Institute at Anglia Ruskin University in the UK, explained the problem: “When you’re looking at a screen up close, your eyes must focus using the ciliary muscle. Over time, especially as we age, that muscle gets tired.”
Here are five expert-backed ways to reduce digital eye strain:
1. Follow the 20-20-20 Rule:
Recommended by the American Optometric Association, this simple strategy involves looking at something 20 feet away for 20 seconds every 20 minutes. “Even a short break like this relaxes the eye muscles and can ease dry eye symptoms,” said Dr. Pardhan.
2. Rethink Your Workspace:
A poorly arranged workstation can increase strain. Screens should be kept at eye level to reduce neck tension, while lighting should be adjusted to reduce glare. “Avoid placing your screen directly in front of or behind a window,” Pardhan advised. Using an anti-reflective screen or soft lighting can also help reduce discomfort.
3. Blink More Often:
Research shows screen use can reduce blinking by up to 66%, increasing the risk of dry eyes. “Blinking spreads moisture across the eye,” Pardhan said. Posting reminders like a simple “Blink!” note near your monitor or using a humidifier can help keep your eyes hydrated.
4. Limit Blue Light Exposure:
High-energy blue light from screens can strain the eyes, especially in dark environments. Most devices now include blue light filters or “night mode” settings. Blue light-blocking glasses can provide additional comfort, though experts note they won’t prevent long-term eye conditions.
5. Be Mindful with Screen Time:
Outside of work, many people default to more screen-based entertainment. Reducing non-essential screen time can offer relief. Apps like Forest and OneSec encourage digital breaks and mindful phone use, helping users become more intentional with their habits.
Health authorities emphasize that while screens are an unavoidable part of modern life, small behavioral changes can make a big difference. Prioritizing eye health now can prevent discomfort and reduce the risk of long-term issues in the future.
