Have your eyes checked regularly. If you need a new or changed prescription, attend to it immediately.
Re-position the computer. The screen should be about an arm’s length away and positioned directly in front of the face, not off to the side. Position the monitor so its center is four to eight inches below the eyes, which allows the neck to relax while we read and type.
Follow guidelines for good posture. It will reduce strain on the back, neck, and shoulders.
Ensure proper lighting. Try the visor test to determine if current lighting is a problem: Look at the monitor and cup the hands over the eyes. If the eyes immediately feel better, then the lighting should be changed. Experiment with brighter and dimmer lighting, as well as the angle of the lights, to find what’s most comfortable for the eyes.
Reduce glare. Installing anti-glare filters on the monitor, adjusting window shades, and changing the screen’s contrast and brightness can help reduce glare and reflections.
Blink frequently. It should prevent dry eyes. If that doesn’t work, consider lubricating eye drops . Also make sure air vents aren’t blowing on the face (this can dry out the eyes), and use a humidifier if the room is super dry.
Take regular work breaks. Stand, stretch, or just look off into the distance, away from the computer, every 15 minutes or so to give the eyes a break.
Clean the monitor regularly. Dust can decrease screen sharpness, making the eyes work harder.
