Computers are now an integral part of our lives. This advancement in science has brought about a vast change in our lives. Despite its benefits, using computers extensively leads to health-related issues, awareness of which is minimal.
Computer vision syndrome (CVS) refers to eye and vision related problems associated with extensive computer use. The primary symptoms are eyestrain, blurred vision, dry, irritated and tired eyes and headaches. Neckache and backache can also be related to the way we use our eyes while using the computer. With the increasing use of computers in day-to-day life, more and more cases of classical Computer Vision Syndrome are encountered everyday.
Computer vision syndrome affects 75% of the people who work on computers, most markedly those who work more than 3 to 4 hours with computers. CVS is often different from other typical eye problems.
Causes of CVS
| |
Uncorrected refractive error |
| |
Inappropriate glasses for computer use |
| |
Strain on the muscle of the eye |
| |
Decreased blink rate or tear functions |
| |
Glare and reflections from the monitor and surroundings |
| |
Ergonomics |
The usual ophthalmic examination focuses more on distant vision (6 m and beyond) and near vision (35 to 40 cm), whereas the computer users have a unique working distance with respect to the monitor, keyboard, mouse, etc. Due to this difference in the working distance, the usual examination does not completely address the actual environment conditions. The Computer Vision Clinic, however, is specially designed to address the varied needs of the computer user.
