My colleague asked me an interesting question the other day. "What should be
the ideal brightness of the computer monitor?Now, this may look simple to
you. But there's more than meets the eye. Explains Dr Mahipal Sachdev,
chairman & medical director, Centre for Sight, New Delhi "Your eyes are
designed primarily for use at distance. So spending long hours looking at a
computer screen can be very demanding for your eyes. Your eyes must focus
and refocus on the images to keep them sharp, which can cause undue stress
to your eye muscles. It's important to note that near work by your eyes
induces myopia."

In fact, when you work on computer, your eyes blink at less than half their
normal rate, which can cause a dry, irritated eyes. "Conditions in your
workplace such as excessive reflections off your computer display, poor
lighting, improper placement of equipment and old monitors may also
contribute to the problem," he adds.

Don't turn a blind eye to this. On an average, more than 50% of the
workforce today uses a computer on the job — and nearly 60 million people
experience computer vision problems. On a serious note, worldwide,
approximately 314 million people suffer from serious vision impairment. Of
these, 45 million people are blind and 124 million have low vision. In
India, an estimated 15 million people are blind, out of which there are 2
million children are blind and every year 3 million people develop

their eyes.
