Are you short﹣sighted？ If you are， your parents might have tried to do something to fix it， such as having you get an eye massage（按摩）， take medicine or even get surgery（手术）． People who offer these services or products often say that they can reduce or even cure short sight．

    However， you will no longer see advertisements like this before long． The government has issued a notice to ban（禁止） businesses from using words like "recovery" or "short sight cure" in

their advertisements．

    The notice says that short sight cannot be completely cured with current medical technology． Therefore， these advertisements could mislead children and their parents．

    Young people can prevent and control short sight by spending more time outside and less time in front of books or computers． People who have sight problems should first go to a hospital and let a doctor decide what to do．

    More than 450 million Chinese have suffered from short sight since June 2018． Short sight rates are around 30 percent for primary school students， 60 percent for junior high school students and 80 percent for senior high school students． This is likely because students spend a lot of time reading books and using electronic devices．

    To reduce short sight among young people， the government made a new plan last August． The plan is designed to limit the amount of time children spend playing video games， as well as limit the production of new video games．
