Many teenagers today spend too much time on phones and computers. I believe parents should limit their screen time for two main reasons.

First, too much screen time can harm teenagers’ health. Spending hours online can cause eye strain, tiredness, and poor sleep. If parents set time limits, teenagers will have more time to rest and exercise.

Second, using screens too often can take time away from studying and family activities. Teenagers may forget homework or waste time on social media. Limiting screen time helps them focus better and use their time wisely.

In conclusion, parents should control teenagers’ screen time to protect their health and help them succeed in school and life.
