Visual Ergonomics
Computer screens combined with other screen time as well as everyday functions can put considerable strain on the eyes. This can lead to work-related stress and other vision problems in the long run. But there is a lot you can do when it comes to your eye health.
About visual ergonomics
Ergonomics are all about designing workplaces that put the least strain on workers. Visual ergonomics are workplace practices that help prevent vision-related problems. These may arise due to continuous screen time such as in front of a computer or other devices
These problems are referred to as Computer Vision Syndrome (CVS) and can manifest as eyestrain, blurry vision, dry eyes and headaches. The cause of CVS are varied such as screen glare, poor lighting, incorrect distance between screen and eyes, poor posture, vision problems or a combination of one or more of these factors.
Visual ergonomics thus help prevent or eliminate CVS and can improve workplace productivity.
Utilizing visual ergonomics
Follow these simple visual ergonomic tips to prevent CVS and ensure good vision and improve your productivity.
- Take frequent breaks from your screen and close your eyes for a few moments. This small act can do wonders for your eye health. You can also try to adjust the focus of the eyes by looking at objects in the distance every hour or so. 20 feet is considered ideal for this exercise.
- Blink frequently; more than you do naturally. This eliminates problem of dry eyes that occurs due to prolonged screen use. For those who wear contact lenses this might be more of a problem. If your dry eye problem persists consult a doctor as they sometimes prescribe eye drops to help with the problem of dry eyes.
- Keep the screen at the appropriate distance. A distance of about 24-28 inches is considered ideal. Make sure the center of the screen is actually 5-6 inches below your eye level.
- Ensure that there are no reflections on the screen from overhead lights or windows. Position your screen in a way that natural light sources are to your side instead of behind you. You can also fit your computer with an anti-glare screen to protect your eyes.
- Undetected or untreated vision problems increase the instances of CVS. If you begin to suffer from prolonged eye strains and find it difficult to see properly then get your eyes checked and follow the prescribed treatments. Those who use bifocals at times find it difficult to look at the screen without tilting their head back. If this is the case with you then you might need to get your vision rechecked or change your glasses. You can also ask your doctor for special screen glasses with protective coating.
