Computer Vision Syndrome

It is a condition which develops as a complex of vision and eye problems due to activities that cause stress to the short vision and commonly experienced when using a computer.It occurs only due to the constant use of computers or any other digital devices. It is important to exercise care if we are working for prolonged hours in front of a computer screen. Eye strain is a common symptom of working in front of a digital device. Although the strain may disappear or reduce once you stop using the computer, it may worsen for some people with existing health conditions.

10 Steps to avoid Computer Vision Syndrome

1. Regular check-up (at least once a year) to see how effectively your eyes are functioning could be of great help.2. Excessive ambient lighting from interior lighting or sunlight could cause eye strain. For comfortable use of a computer, ambient lighting must be half as bright as found in office spaces.3. Glare on walls, reflections on computer screens and eyes is another common cause. Minimize glare by installing an anti-glare screen on the monitor.4. Upgrade monitor from the old tube-style ( cathode ray tube) to a flat-panel Liquid Crystal Display (LCD) style.5. Severe Computer Vision Syndrome can also be caused by too much brightness and contrast to the computer screen. Adjust the display setting to suit your vision.6. Blinking is very important and it does not happen when viewing a computer. It keeps the eyes moist, comfortable and clear.7. Eyes experience fatigue due to focusing and it is important to exercise your eyes. Practice a few eye exercises in between breaks.8. Take short frequent breaks away from the computer for 20 seconds every 20 minutes. Stretch your arms, loosen your shoulders and bend your back to reduce the risk of Computer Vision Syndrome.9. Modify your workstation if you need to look at the print paper and the computer screen. Place the print paper in line with the computer screen to avoid pressure.10. Consider wearing computer eyewear and it may be beneficial to get customized glassed to wear while working on the computer.
