For better eyesight(视力), doctors advise limiting(限制)the hours of screen time and encourage having enough eye resting time．
However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia(近视)．An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia．The research team found that there were less children who had myopia in Sydney than those in Singapore, even though they spent more time in front of computer and TV screens．The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore．
Indoor and outdoor sports both make the eyes pay attention to more distant(远处的)objects, which stops the eyes from changing original shape．But outdoor sports may be better than indoor sports for myopia．Because natural light is good for eye growth and vitamin(维他命)D from the sunlight might be useful to it．Many doctors suggest that every child get its first eye test when he/she is about two and half years old, and even if his/her sight seems good enough．It is necessary for myopic(近视的)children to wear glasses to stop headaches, trouble reading and so on．It is also important that schools invite doctors to test their students’ eyes．
If that is not possible, school teachers should at least encourage parents and children to have regular eye examination and wear glasses．And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors．
