Taking care of your vision

Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive 
room lighting, poorly focused screens, very small typefaces and low-contrast 
displays could stress your eyes. The following sections provide suggestions on 
how to reduce eyestrain.
Eyes

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.

Display

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

using a glare-reduction filter

using a display visor, such as a piece of cardboard extended from the 
display's top front edge

Avoid adjusting your display to an awkward viewing angle.

Avoid looking at bright light sources, such as open windows, for extended 
periods of time.

Developing good work habits

Develop the following work habits to make your computer use more relaxing 
and productive:

Take short breaks regularly and often.

Perform some stretching exercises.

Breathe fresh air as often as possible.

Exercise regularly and maintain a healthy body.
