Nowadays many teenagers spend hours using phones, computers, and televisions every day. I believe that parents should strictly limit teenagers’ screen time for several reasons.

First, too much screen time leaves little time for homework and real-life activities. Many teenagers spend hours watching online videos, checking social media, or playing computer games, so they often cannot finish their schoolwork. As a result, their academic performance may fall. Second, spending too much time in front of screens is harmful to health. Long hours with phones or computers can damage eyesight, reduce sleep, and even cause weight gain because teenagers sit still for too long. In conclusion, parents should set clear limits on how long their children use screens each day. By doing this, they help teenagers protect their health, focus on studying, and develop balanced lifestyles.
