For better eyesight, doctors advise limiting the hours of screen time and encourage having enough eye resting time.
However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia（近视）. An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.
The research team found that the prevalence（流行）of myopia among children in Sydney was lower than children in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore.
Indoor and outdoor sports activities both make the eyes focus on more distant objects, which prevents the eyes from changing shape. But outdoor activities may better help avoid myopia than indoor sports activities.
Jane Gwiazda, who does research in sight problems, says: “Natural light is good for eye growth. And extra vitamin D from the sun might contribute to eye growth.”
Many doctors suggest that every child get its first eye test done when he/she is about two and half years old, and even if his/her sight seems perfect.
It is necessary for myopic children to wear glasses to prevent headaches, trouble reading or injuries. It is also important that schools invite doctors to test their students’ eyes.
If that is not possible, school teachers should at least encourage parents and children to have regular eye examinations and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors.

For a while, my neighborhood was taken ever by an army of joggers(慢跑者). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. “Come on!” My friend Alex encouraged me to join him as he jogged by my house every evening. “You’ll feel great.”
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I’m not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet a real pounding（追击）ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn’t kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn’t my idea of fun. Jogging is also a lonely pastime. Some joggers say, “I love being out there with just my thoughts” Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn’t just the first week: it was practically every day for two months. I never got past the pain level, and pain isn’t fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don’t jog any more, and I don’t think I ever will. I’m walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I’m getting exercise, and I’m enjoying it at the same time. I could never say the same for jogging, and I’ve found a lot of better ways to stay in shape.
