Computer Vision Syndrome - Know Reasons Behind It!

Eye problems that are caused due to the computer can be termed as Computer Vision Syndrome. Staring on a computer screen has become a part of our daily lives, for many of us. Work and pleasure both include using a computer or a tablet. Looking at this screen for prolonged periods can cause many problems including strain, pain and stress due to the repeated eyeball movements and non-blinking nature of the work that we do when we stare at a screen for many hours. Let us find out more about the causes of computer vision syndrome or CVS.

Causes of CVS:

Viewing a computer screen for a prolonged period makes the eyes work harder. Thus, the unique characteristics and high visual demands of computer screen device viewing make many individuals susceptible to the development of vision-related symptoms.

Uncorrected vision problems such as myopia, hypermetropia, presbyopia, etc can increase the severity of the problem.

Even people with contact lens may suffer from this problem. Sometimes, people tilt their heads at an odd angle because their glasses are not designed for looking at a computer screen. These postures can lead to muscle spasms or pain in the neck, shoulder or back.

Apart from all these factors, working on a computer gets even more challenging after a certain age like forties and above.

Symptoms of CVS:

There is no damage per se, but a constant strain on the eyes leads to:

1. Blurred vision
2. Double vision
3. Dryness of the eyes
4. Redness of the eyes
5. Irritation of the eyes
6. Headaches and neck/back aches

Treatment

Treatment is definitely an option once the problem sets in, but this is a condition which can be definitely prevented with some simple, effective steps.

1. Antiglare coating: This coating virtually eliminates the reflections from front and back surfaces of your eyeglass, thus reducing strain on your eyes while using electronic gadgets.
2. Proper prescription glasses: Proper glasses should be worn regularly as prescribed by the doctor.
3. Desk arrangement: Make sure the desk or monitor is slightly below eye level, about 30 inches away from the face. If you are straining the neck or the back to look at the monitor, it requires a change. The chair also can be changed in height to suit the seating. Also, prints can be pinned to the workstation when something is being typed, so constantly looking up and down while typing is avoided.
4. Screen type: Move away from the older tube-style monitor with an LCD screen, which is easier on the eye. Check the computer settings so that brightness, contrast, and font size and shape and contrast are altered to suit your convenience. Ensure you are not requiring to strain to read.
5. Alter the lighting: Look around you, and ensure there is adequate lighting with no glares on the monitor from surrounding windows or bright lights. A glare filter on the monitor is an effective way to manage this.
6. Rest your eyes: Follow the 20-20-20 rule, with a 20-second break every 20 minutes where you look at something 20 feet away.
7. Keep them moist: Blink your eyes constantly to ensure there is enough moisture. Eye drops can be used if required additionally.
8. Frequent breaks: Not just your eyes, this also reduces strain on the neck and the back.
9. Regular eye checkups: An annual visit, especially after 40, is a must for optimal eye health. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
