- If you view your monitor more than your documents, place the display at the center
of your desk to minimize neck strain.
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 for extended periods of time.
