Using a computer for long periods is one of the most common causes of eyestrain. This type of eyestrain is called computer vision syndrome.
Here are some tips for reducing computer eye strain:
- Compared with when you are reading printed material, when you are using a computer, your eyes blink about five times less often. Blinking is good! Blinking produces tears that can help moisten and lubricate your eyes.
- Keep the top of your screen at eye level or below so that you look down slightly at your work.
- If you work in a very bright office environment, you could reduce overhead lighting to make your surroundings the same brightness (or slightly dimmer) than the background on your screen. Computer monitor is a source of light itself, so it doesn’t require additional illumination. Use a floor or desk lamp to throw a spotlight on papers. Too much contrast between the screen and the surrounding environment can cause eyestrain.
- Take eye breaks. Throughout the day, give your eyes a break by forcing them to focus on something other than on your computer screen. Try to give yourself a five-minute rest every hour.
