Use proper lighting.
Eye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices. Eliminate exterior light by closing drapes, shades or blinds. Glare on walls and finished surfaces, as well as reflections on your computer screen also can cause computer eye strain.
Upgrade your display.
If you have not already done so, replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel liquid crystal display (LCD), like those on laptop computers.
Adjust your computer display settings.
Adjusting the display settings “ brightness and contract -of your computer can help reduce eye strain and fatigue. Adjust the text size for comfort, especially when reading or composing long documents. Usually, black print on a white background is the best combination for comfort.
Blink
Blinking is very important when working at a computer; blinking moistens your eyes to prevent dryness and irritation. When working at a computer, people blink less frequently ” about one-third as often as they normally do ” and many blinks performed during computer work are only partial lid closures, according to studies.
Take frequent breaks.
To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.
Modify your workstation.
If you need to look back and forth between a printed page and your computer screen, this can cause eye strain. Place written pages on a copy stand adjacent to the monitor.
