How can computer vision syndrome be alleviated?

The 20-20-20 rule is an effective strategy for alleviating computer vision syndrome, which is a condition that arises from prolonged exposure to screens, leading to symptoms like eye strain, dryness, and discomfort. This rule encourages individuals to take a brief moment to rest their eyes by focusing on something at least 20 feet away for 20 seconds after every 20 minutes of screen time. This practice helps reduce eye fatigue by allowing the eye muscles to relax, which is essential when they are often locked in a fixed position while viewing screens.

In contrast, while taking a break every hour may seem beneficial, it doesn't focus on the regular short breaks that the eyes need during screen use. Switching to brighter screens can potentially increase eye strain rather than mitigate it, as more intense light can exacerbate discomfort. Reducing screen time to under two hours a day might not be practical for many individuals, especially if screen time is integral to their work or daily activities. Therefore, the 20-20-20 rule stands out as a structured, manageable method specifically designed to combat the symptoms associated with extended screen use.
