眼保健操做了很多年还是近视了,还用做下去吗?

2017-06-07 07:27:18   新华社

在中医领域,眼保健操出现了“升级版”。国医大师贺普仁根据中医的经络学发明了“贺氏三通法”,该方法主要由对眼睛周围穴位进行电梅花针叩击治疗、雷火炙,以及“贴耳豆”三种中医技法组成,相当于“医院版”的眼保健操。

杨迎新介绍,假性近视的原理主要是睫状肌调节痉挛,现称为调节滞后。“对假性近视的治疗要重视。正常情况下,孩子的近视度数每年会增加50度,采用一定的方法治疗,每年可能只增加约20度,能让孩子延缓发展为真性近视。”杨迎新说。

预防、延缓近视都有哪些方法?

多位受访眼科专家建议,减少近距离用眼、增加户外活动、追踪屈光发育情况、及时筛查佩戴眼镜等,都对预防、延缓孩子近视的发生、发展有积极作用。

李莉说,减少近距离用眼及增加户外活动是防控近视的有效手段。建议孩子近距离用眼半小时后,向远处眺望或做做眼保健操缓解一下疲劳。现在很多孩子经常处于室内环境,对保护视力不利,课间休息时应到户外活动。有循证研究表明,每天2小时的户外运动有助于降低近视发生、发展的机率。

李莉建议,对于有近视遗传因素或喜欢近距离视物的孩子,要早做筛查,健康用眼,一旦确诊是近视就要配戴眼镜。如果不配戴眼镜,孩子为了看清远处的物体,眼睛会过度使用调节功能,反而会加速近视发展。

北京同仁医院眼科副研究员李仕明说,近视发生、发展的主要年龄在6岁至12岁,随着眼轴发育,少年儿童平均每年近视度数增加50度至75度。孩子的视力变化和身高体重是一样的,符合一定的年龄规律,因此建议给孩子建立连续的视觉健康档案,追踪屈光发育情况。

王宁利介绍,北京同仁医院对近视眼的研究已取得了一些初步成果,比如通过手机应用,监控孩子的户外活动时间等生活学习模式。此外,医院也在研发低浓度的阿托品滴眼液,在晚上使用后可能对近视眼进展有延缓作用。医院希望通过与教委合作等方式,逐步地将有效的防控技术推广到学校,减少孩子的近视患病率。(参与采写:韩扬眉)来源新华社)
