20-20-20 rule

What does 20-20-20 rule mean?

The 20-20-20 rule is a technique used to prevent eye strain and fatigue when working at a Computer for extended periods. The rule states that every 20 minutes, you should look away from the computer screen and focus on something at least 20 feet away for at least 20 seconds.

The 20-20-20 rule is based on the fact that the eye’s natural resting point is about 20 feet away. When you look at a computer screen, your eyes are forced to focus on a close Object for an extended period of time. This can lead to eye strain, fatigue, and other problems.

The 20-20-20 rule helps to prevent eye strain and fatigue by giving your eyes a chance to relax and refocus. By Following the rule, you can help to protect your eyes and improve your overall eye health.

History

The 20-20-20 rule was first introduced in the 1990s by a team of ophthalmologists at the University of California, Berkeley. The team was studying the effects of computer use on eye health and found that people who followed the 20-20-20 rule experienced Less eye strain and fatigue.

The 20-20-20 rule has since been adopted by a number of organizations, including the American Optometric Association and the National Institute for Occupational Safety and Health. The rule is now widely recognized as an effective way to prevent eye strain and fatigue among computer users.
