Short-sightedness is a common problem among Chinese students. It refers to the inability to see objects at a distance clearly. These days more and more Chinese students are affected by short-sightedness, increasingly at a younger age.
According to a national survey of students’ health, the percentage of Chinese primary school students who suffer from short-sightedness is thirty-six per cent. Among junior high school students, the number increases to seventy-one point six per cent, and as for senior high school students, eighty-one per cent of them need to wear glasses. These high figures worry both teachers and parents. Short-sightedness can have a significant effect on students. It can make it inconvenient for them to play certain sports, such as basketball and swimming. In some cases, it may even give rise to other eye problems.
Listening :listen again and finish A2
What causes short-sightedness has not been fully understood. It is commonly believed that people whose parents are short-sighted are more likely to suffer from the condition. However, how people use their eyes may be a key factor. Individuals who spend a large amount of time reading, working at a computer, focusing on a smartphone screen or doing other close work are at higher risk of developing short-sightedness. These activities become even more dangerous when coupled with poor lighting or bad reading habits such as reading in bed. Spending too little time outdoors can also cause the problem.
Students with short-sightedness may look at things with their eyes partly shut or move closer to objects to see clearly. Sometimes they may complain of tired eyes and headaches. These are all signs of short-sightedness.
