numbness, or a burning or tingling sensation

aching, soreness or tenderness

pain, swelling or throbbing

stiffness or tightness

coldness or weakness

If you have these symptoms, or any other recurring or persistent discomfort and/or pain related to computer use, consult a physician immediately and inform your company's health and safety department.

The following section provides tips for more comfortable computer use.

Finding your comfort zone

Rest your eyes frequently.

Give your eyes regular breaks by looking away from the monitor and focusing on a distant point.

Blink frequently to keep your eyes from drying out.


Keep your display clean.

Keep your head at a higher level than the top edge of the display so your eyes point downward when looking at the middle of the display.

Adjust the display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity.

Eliminate glare and reflections by:

placing your display in such a way that the side faces the window or any light source

minimizing room light by using drapes, shades or blinds

using a task light

changing the display's viewing angle
