当前,学校对学生的视力保护都很重视,但在校学生中眼睛的疾病还是时有发生,影响了学生的学习和生活。究其发病原因固然很多,做眼保健操前不注意手的卫生就是一个重要因素。据有关资料表明,一个普通人未经洗净的双手带有细菌数高达4～40万个,而每克指甲的污垢中含有细菌约38亿个之多。这些细菌中相当部分是致病菌,也含有沙眼和急性结膜炎的病原体。学生特别喜欢活动,平时打球、翻书、玩泥土、做作业等都要使用双手。如果用脏手做眼保健操,手上的细菌就会在做操时进入眼中,导致眼病。眼保健操对学生来说确实是一种很好的眼睛保健方法,但如只重视做眼保健操,忽视学生
At present, the school attaches great importance to the protection of students’ vision, but the eye diseases of school students still occur from time to time, affecting students’ learning and life. Although there are many causes of the disease, it is an important factor to pay attention to hand hygiene before doing eye exercises. According to relevant information, an ordinary person’s unwashed hands carry up to 40,000 to 400,000 bacteria, and the dirt contained in nails per gram is about 3.8 billion bacteria. A significant portion of these bacteria are pathogenic bacteria and also contain pathogens for trachoma and acute conjunctivitis. Students particularly like activities. They usually use their hands to play ball, turn books, play clay, and do homework. If you use dirty hands to do eye exercises, the bacteria in your hands will enter the eyes when doing exercises, leading to eye diseases. Eye exercises are indeed a good eye health care method for students, but they only pay attention to eye exercises and ignore students.
