With smartphones, computers and tablets now part of everyday life, prolonged screen use can cause eye strain and discomfort. Simple habits can help reduce the impact of digital devices on eye health.
When screens become a challenge for the eyes
From work and school to entertainment and communication, screens occupy an important place in daily life. However, spending several hours a day looking at digital devices can lead to a condition commonly known as digital eye strain.
People affected may experience dry eyes, blurred vision, headaches, eye fatigue or difficulty focusing after long periods of screen use. This discomfort is often linked to reduced blinking when concentrating on a screen, as well as exposure to bright light and poor viewing habits.
Adopt the 20-20-20 rule
One of the simplest ways to reduce eye strain is to take regular breaks. Eye specialists recommend the 20-20-20 rule: every 20 minutes, look at an object about 20 feet away, or around six meters, for at least 20 seconds.
These short breaks allow the eye muscles to relax and reduce the effort required to maintain focus. Standing up, stretching and moving away from the screen during longer work sessions can also help protect overall comfort.
Adjust screen settings and distance
The way a screen is used can have a major impact on eye health. Keeping the screen at a comfortable distance, usually about an arm’s length away, helps avoid unnecessary strain. The top of the screen should ideally be positioned slightly below eye level to maintain a natural posture.
Adjusting brightness, increasing text size and reducing glare can also make viewing more comfortable. Using screens in a room with adequate lighting is preferable to looking at a bright device in complete darkness.
Remember to blink and protect eye moisture
When focusing on a screen, people tend to blink less often, which can cause dryness and irritation. Making a conscious effort to blink regularly helps maintain the natural moisture of the eyes.
For people who frequently experience dry eyes, an eye care professional can provide advice on appropriate solutions. It is also important to avoid rubbing the eyes, as this may increase irritation.
Healthy habits for long-term eye protection
Protecting eyesight goes beyond managing screen time. A balanced diet rich in nutrients such as vitamin A, regular physical activity and sufficient sleep contribute to good eye health.
Children and adolescents require particular attention, as their use of digital devices continues to increase. Encouraging outdoor activities and setting reasonable screen limits can help promote healthier visual habits from an early age.
Screens are unlikely to disappear from everyday life, but responsible use can reduce their effects on the eyes. By adopting simple protective habits, everyone can maintain better visual comfort while benefiting from digital technology.
