Working at a computer has become a routine for many people, not to mention the hours some of us spend gaming, browsing the internet, social networking or simply watching entertainment programs on a computer screen. All of this time spent in front of a computer screen (according to some statistics, even 3 hours can be too much, especially if you don’t take certain precautionary measures) will eventually lead to developing what is now called computer vision syndrome – eye strain and a series of other eyes, vision and muscular symptoms that can slow down your productivity and, if ignored, even cause permanent eye damage.
Computer vision syndrome – main causes
- Prolongued and uninterrupted focusing.
- Excessive brightness of the computer screen.
- Low contrast, especially when working with text.
- Reduced blinking, from an average of 12-24 blinks per minute, to as low as 6 blinks per minute.

- Adjust your seat and the position of the monitor so that the top of the screen is at eye level and the gaze angle at 10-20 degrees below the eye.
- If you have to work with printed documents while you are using the computer, make sure they are positioned at the same height and distance as the computer screen.
- Adjust the brightness and contrast of the screen until you feel as comfortable as possible.
- Wipe the screen every morning.
- Use an anti-glare filter or a computer monitor with an anti-glare screen.
- Wear a small plus-powered (+1.00 to +1.50) pair of eyeglasses with UV and blue light filtering lenses.
- Follow the 20-20-20 rule: every 20 minutes look away from the computer screen and for at least 20 seconds focus on an object situated at a distance of at least 20 feet.
