For working at the computer, indirect or shielded lighting is
best, and it should light your entire office equally. Make sure
the lighting is not too bright, because this can make your eyes
tired from continually readjusting between the relative dimness
of the screen and the bright surroundings. You can use window
blinds, shades, or drapes to control the amount of daylight in
the room or reduce overhead lighting by turning off or
dimming the lights.
Here is a simple way you can test your lighting. While looking
at the screen, use your hand to shield your eyes from the
brightest light source in the room (such as a window or
overhead light). If you feel a sense of relief, no matter how
small, your current lighting is too bright.
Using the Keyboard and Mouse
Constant use of a keyboard, mouse, or any
pointing device can lead to a variety of aches and
strains. To prevent injury, keep your hands
relaxed and rest them frequently
Try to keep your fingers parallel with your forearms to prevent
straining your wrists. Adjust the angle of the keyboard so the
slope is no more than 25 degrees. (The keyboard has legs on the
bottom which allow you to adjust the angle.)
Keep your hands and fingers relaxed when you are typing and
try not to press the keys too hard; using too much force creates
tension in your hands. Remove your hands from the keyboard
when you are not using it and take frequent breaks to stretch
your hands and fingers.
When using a mouse, keep your wrist and fingers relaxed. Let
go of the mouse frequently and stretch or relax your hand.
Leave enough space on your work surface so you can freely
move the mouse.
