暗处玩手机很伤眼

2017-09-06 10:11:55   中国青年网

无论是看书写字还是玩手机,环境太亮或者太暗,都容易产生视疲劳。而长时间在暗环境中玩手机,瞳孔会放大,眼压可能会升高,长此以往就可能引发青光眼,尤其是有青光眼家族史的人。另外,孩子的巩膜比较软,眼压升高,眼球会逐渐变大,容易发生近视或近视度数加深。

预防孩子视力下降,要让其养成良好的用眼习惯:1.多去户外活动,对尚未近视的孩子来说,多参与户外活动,可以有效预防近视;2.注意用眼距离、时长,每用眼30~40分钟,休息10分钟;3.尽量减少电子设备的使用,每次控制在10~15分钟之内;4.室内光线要柔和,室内灯光尽量不要直对眼睛或屏幕;5.保持充足的睡眠及均衡营养。体内缺乏维生素A、维生素B1、维生素B12、维生素C、维生素E和维生素D以及钙、锌等元素,易导致假性近视,所以饮食中要注意摄取。
