中学生视力在下降,这已是一个老问题,也是一个新讯号。学习紧张,课外作业过多,坐姿不当,灯光不明,看电视和食糖过多,均被认为是导致中学生视力下降的原因。但最近日本科田大学医学部教授岛田彰夫提出新观点:平日常吃软食或流汁,不很好地进行咀嚼是造成视力下降的又一原因。
The sight of middle school students is declining. This is an old question and a new sign. Tense study, extracurricular homework, poor sitting position, unknown lighting, watching TV and too much sugar were all considered to be responsible for the decline of sight in middle school students. However, recently, Professor Shimada Shimada, a professor of medicine at Kitakatsu University, put forward new ideas: eating soft drinks or juice daily, and chewing poorly is another reason for the loss of vision.
