Long hours of screen work cause eye fatigue, dryness, headaches, and reduced concentration. These symptoms are referred to as digital eye strain, and they can be avoided with a few simple habits.
Why Eyes Get Tired
Constantly looking at the monitor, screen flickering, infrequent blinking, and dry air lead to strain. As a result, the following occur:
- burning and sandy sensation;
- redness and blurred vision;
- headaches and fatigue.
If these signs are ignored, vision will gradually deteriorate.
How to Preserve Vision
-
The 20-20-20 Rule
Every 20 minutes, take a break: look at an object about 6 meters away for 20 seconds. -
Blink More Often
While working at the screen, blinking decreases by 3–4 times. Every hour, make 10 slow blinks to moisten your eyes. -
Adjust Lighting
Avoid bright lamps behind you and glare on the monitor. Work in soft, diffused light. -
Adjust the Monitor
The monitor should be at eye level or slightly below, at a distance of 50–70 cm. Adjust brightness and enable eye protection mode (Night Shift, Eye Comfort, Dark Mode). -
Use Blue Light Filtering Glasses
Even without vision problems, they reduce strain and protect the retina. -
Do Eye Exercises
Look alternately at distant and near objects for 10 seconds, repeating 5–10 times. This trains focus. -
Ventilate the Room and Humidify the Air
Dry air increases irritation. Use a humidifier or simply place a bowl of water nearby. -
Watch Your Posture
Keep your head straight, do not slouch. Neck tension directly affects eye fatigue. -
Enable Dark Mode
Dark Mode reduces brightness and helps the eyes rest while reading and working with text. -
Visit an Ophthalmologist Once a Year
Even if there are no problems, a preventive check-up helps identify issues in time.
Working on a computer is not an enemy to vision if you maintain balance and give your eyes a break.
