Computers are now an integral part of our life. They are now an essential component of all spheres of our lives- studies, work, leisure and even family time.

This advancement of Technology has overtaken our lives to the extent that we wonder what our lives will be without it. With all its benefits come certain Health related issues, awareness of which is minimal. This increased Technology-driven lifestyle can have adverse effects on our Eye Health. As per research and findings by Specialists between 60% and 90% of people who work at a computer screen have at least some symptoms caused due to visual display screen.

What is computer vision syndrome (CVS)?

Computer Vision Syndrome (CVS) is a complex of eye and vision problems that result from prolonged use of Laptops, Tablets, Smart phones and Computers. They are usually caused by a combination of improper seating posture, poor lighting in the room, glare from the computer screen, sitting too close or too far from the screen, and uncorrected eye health disorders.

How does it affect the eyes and its symptoms

Computer Vision Syndrome is similar to carpal tunnel syndrome and other repetitive motion injuries you might get at work. It happens because eyes follow the same light path again and again. Long hours before the screens make the problem worse with the contrast, flicker and glare of the screen. As a result, high visual demands of computer and digital screen device viewing make many individuals susceptible to the development to the vision- related symptoms. In due course leads to eye strain and discomfort and you may have-

 Neck and back painŸ

How to prevent the computer vision syndrome

Computer Vision Syndrome can be avoided by taking the following simple corrective measures:

 Make sure your seat is comfortable. A comfortable chair withŸ support for your neck and back will help you avoid neck and shoulder strain.

 Position the digital display so that your head is in a naturally comfortable position while using.Ÿ

 Ensure your visual display screen is properly placed. It shouldŸ be 10 to 20 degrees below your eye level as measured from the screen’s centre, and about 20 to 26 inches away from your eyes.

 Follow the 20-20-20 method. Look away from the screen every 20Ÿ minutes or so and look at something around 20 feet away for 20 seconds. Blink often to keep your eyes moist.

 Use lighting that is neither too dim nor too bright. Also use anti-glare screens to minimize the glare from light sources.Ÿ

 Adjust the settings of brightness, contrast, and font size until your eyes feel comfortable.Ÿ

Prevention is better than cure

Eyes are amongst the most special assets. You must take care of your eyes. It is best to consult an Ophthalmologist for any problem with your eyes or any changes in your vision. He will examine you and advice you on how to resolve the problems. At the slightest hint of any eye problem that your child tells you, it is best to get the child’s eyes examined at the earliest. The older you get, it is better to see your Ophthalmologist at least once a year. If you notice any changes in your vision please do consult an Ophthalmologist immediately and tell him your problems. He may prescribe glasses or contact lenses and explain you the Dos and Don’ts. Early detection can avoid a visual challenge.
