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.
