If you find yourself staring at screens all day long, whether it’s a TV screen, computer screen, or smartphone screen, your eyes will inevitably get tired.

Therefore, the 20-20-20 rule is the best solution for you to protect yourself from the problem.

In a study published by the Nepalese Journal of Ophthalmology in 2013, researchers examined the effect of computer use on the eyes of university students in Malaysia.

Nearly 90% of the 795 students had symptoms of eye strain after only two hours of continuous computer use.

But when these students took frequent breaks to look at distant objects while using computers, the symptoms of eye fatigue decreased significantly, and thus they concluded that the 20-20-20 rule was the best line of eye defense.
