Computers, once the darlings of the modern world, now represent the
flickering face of office perjury. Apparently some people even use
computers for recreation, and not just Luddite rockstars throwing laptops
from their thatch roofed highrise hotel rooms. Now some genius has turned
up telling us that computers are evil and dangerous. Like, tell us
something we didn't know. Fortunately, the said expert then proceeded to
tell us some things we didn't know. Hope these tips help you regain
friendly relations with your desktop chum.

Reading the screen

Any task that involves staring at a computer screen, no matter how
exciting or interesting, leads to physical fatigue. You may be quite
happy to press on with work, but your body may have other ideas. The most
common physical complaints are eyestrain and problems with vision
(blurring and itching being typical). Headaches are also a product of
prolonged staring at a screen.

1. Adjust the brightness and contrast controls on the screen to suit the
lighting conditions in the room.

2. Make sure the screen surface is clean.

3. In setting up software, choose an option that makes large enough to
read easily on your screen, when you are sitting in a normal, comfortable
working position. Select colors that are easy on the eye (avoid red text
on a blue background, or vice-versa).

4. Individual characters on the screen should be sharply focused and
should not flicker or move. If they do, the VDU may need servicing or
adjustment.

5. Remember to look away from the screen when you don't need to use it.

Keyboard and mouse

Wrist and hand problems are common when using computers, according to Dr
Han. For example, 'floating' your hand over the mouse for long periods
leads to strain on the ligaments in the back of the hand and the wrist.
Over time, health problems may occur as a result of high retition of hand
movements, forceful typing, or having bent wrists whilst using the
keyboard. Carpal tunnel syndrome is a painful condition that affects the
wrists and hands following pressure to the median nerve. Numbness may
also be experienced in one or both hands and even the simplest of tasks
involving the hands becomes a painful and sometimes impossible activity.

1. Adjust your keyboard to get a good keying position. A space in front
of the keyboard is sometimes helpful for resting the hands and wrists
when not keying.

2. Try to keep your wrists straight. Keep a soft touch on the keys and
don't overstretch you fingers. Good keyboard technique is mportant.

3. Position the mouse within easy reach, so it can be used with the wrist
straight. Sit upright and close to the desk, so you don't have to work
with your mouse arm stretched. Move the keyboard out of the way f it is
not being used.

4. Support your forearm on the desk, and don't grip the mouse too
tightly.5. Rest your fingers lightly on the buttons and do not press them
hard.
