Information for your safety and comfort - 21 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 every 5-10 minutes for every 1 hour of viewing. • 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.
