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 reections 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 lter
• 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.
