Consistent implementation of the 20-20-20 rule can help prevent what?

The 20-20-20 rule is a guideline designed to reduce eye strain, particularly for individuals who spend extended periods looking at digital devices. The rule suggests that for every 20 minutes of screen time, a person should take a break and look at something 20 feet away for at least 20 seconds. This practice helps relax the eye muscles and reduces the risk of digital eye strain, which can manifest through symptoms such as discomfort, dryness, and fatigue in the eyes.

While applying the 20-20-20 rule can also contribute to alleviating fatigue, glare, and dry eyes to some extent, its primary focus is on preventing digital eye strain by encouraging regular breaks that allow the eyes to refocus and recover. Thus, consistent implementation of this rule is particularly effective in combating the discomfort associated with prolonged screen use and mitigating the effects of digital eye strain.
