帮我写一下下面英文的概括,30字左右,用英文~~~~~麻烦了
There’s a growing epidemic of short sightedness around the world. Up to 90% of some Asian communities are affected and around a half of European populations. And more and more evidence is coming in that a child’s visual environment is very important in causing it.
Shortsighted people tend to have longer eyes which means that light rays focus in front of the retina at the back of the eye instead of on it. If parents are short-sighted then their offspring are more likely to be born with longer eyes. The worse the parents’ vision, the stronger the link.
But animal experiments have found that eye development can be significantly affected by visual experiences in early life.
Prolonged looking at things near to the eyes, through tasks like reading, is thought to cause a blurred image on the retina which then responds by producing chemicals which stimulate the eye to grow longer. This becomes a vicious cycle made worse if you have a genetic predisposition.
Given that you don’t want to discourage reading or computer work, eye specialists are experimenting with all sorts of ways of preventing short-sightedness from getting worse. Some are trying drops that dilate the pupil and allow better near focus. Others are trying bifocals in children while yet another way might be using contact lenses earlier in life.
The advice apparently is to correct a child’s myopia but don’t over correct as it could make the situation worse.
