The following sections provide suggestions on how to reduce eyestrain. 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 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. Exercise regularly and maintain a healthy body. We do not recommend using the product on a couch or bed. If this is unavoidable, work for only short periods, take breaks regularly, and do some stretching exercises. 15.
