    1. Move your computer monitor away from the window

    Extraneous light, or glare, is the greatest source of eyestrain for computer users. No matter where your computer screen is relative to a window, adjustable shades, curtains or blinds should be used to effectively control light throughout the day. Avoid facing an un-shaded window, as the difference in brightness between the screen and the outdoors may cause eye stress and discomfort. Consider an anti-glare screen to further reduce reflections.

    2. Adjust your monitor height

    For maximum eye comfort, place the center of the screen five to nine inches below your horizontal line of sight. You should be looking just over the top of the monitor in your straight-ahead gaze.

    3. Check your contacts

    Studies show that when looking at a computer or digital screen, people spend more time concentrating and blink less frequently (up to three times less than normal). Long periods of non-blinking can cause the surface of your eyes and contact lenses to dry out, which can lead to discomfort and loss of visual clarity. Talk to an eye care professional about lenses that provide wearers with increased moisture all day.

    4. Adjust your computer display

    Modifying your monitor display settings can help reduce eye strain and fatigue. Alter the brightness of your display so it is the same as the brightness of your surrounding workstation. When reading long documents, modify them so they you are reviewing black print on a white background.

    5. Take breaks

    The eyes are not meant for seeing at a close distance for hours at a time without a break. Follow the 20/20/20 rule: Take a 20-second break every 20 minutes. Focus your eyes on points at least 20 feet from your computer. Keep your eyes moving while looking at objects at various distances.

    6. Adjust your monitor distance

    If you can touch the screen when you sit back in your chair, the monitor is too close. Use the “One Third Rule.” With your monitor on, displaying a typical document or email you use every day, move back from the screen until it just starts to become blurred. Measure this distance and divide by three; your monitor should be placed at that distance.

    7. See your eye care professional

    For those who work in front of a computer or digital screen all day long, annual eye exams are a must. If at any time you experience any vision problems or discomfort, talk to your eye care professional.

    8. Use proper lighting indoors

    Avoid working under overhead fluorescent lights if possible. Choose floor or desk lamps instead that provide indirect lighting. Do the mirror test: Take a pocket mirror and put it on your computer screen. If you see a light bulb or other bright source of light behind you, you need to reposition your monitor to reduce the glare.

    9. Hold digital devices farther away

    There have been several studies that show that people hold digital material closer than they would if they were looking at printed materials, like a newspaper. The closer you hold something to your eyes, the more stress you put on them. Make a conscious effort to hold digital devices like your smart phone, farther away from your eyes than normal; adjust the settings if needed to enable larger print.

    10. Affix paper documents so they are in line with your monitor

    Many people tend to situate their work so that they are constantly looking off to one side or flat on the table next to the screen. This requires frequently eye, head and/or torso movement to look back and forth. Affix a spring-loaded document holder to your monitor, so that the eyes can focus and converge in their normal plane of motion (i.e. down and in).
