Lisa likes going shopping very much. She often goes to clothes stores with her classmates on weekends. One day she sees a colorful sweater in the Fashion Clothes Store. It's a red-blue-yellow sweater. There is a card on it. It says 80 yuan. Lisa goes home quickly and collects(搜集) all her money. But she feels sad. She's only got 65 yuan.
After two weeks, the Fashion Clothes Store has sweaters at very good prices——only 80%. Lisa thinks she can buy the sweater with 64 yuan. When she sees the card, it says 100 yuan.
Some weeks later, the store says their sweaters are on sale. You can only pay(支付) 50% for the sweater. Lisa thinks she can get the sweater this time, because it only costs 40 yuan. But when she sees the card, she is very angry. It is 160 yuan.
Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later,her eyesight(视力)dropped to 300 degrees. This is serious for such a young child.
Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"
"There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "
Doctors and scientists say children's vision(视觉)is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright(明亮的)LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.
Doctors advise that users should hold their iPads between 40-60 centimeters(厘米)away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.
