孩子想游泳 最好戴泳镜

2017-08-13 14:52:24   中国青年网

除了尺寸,还需要考虑游泳镜的构造材质。我们普通人在购买泳镜时,不必像游泳运动员那样对泳镜有太专业的要求,但以下几方面还是要注意的,比如游泳镜镜面的清晰度和透光度,泳镜带的弹性及牢固性,游泳镜表面是否有保护胶膜,游泳镜的外橡胶圈的软硬及松紧度是否合适,还要注意泳镜鼻梁处的宽度是否可调,其宽度应当与瞳距及脸型大小相符,购买前一定要试戴。

此外,还应当简单检查一下游泳镜的防雾效果,可以对着游泳镜内侧哈气,雾气消失快的泳镜防雾效果较好。另外,常在户外强烈光照下游泳的朋友可以选择防紫外线的款式,而室内泳池则没有必要。

近视眼怎么办

由于光线在水中会发生折射,并且游泳镜与眼睛的距离比框架眼镜更近,所以,对于单纯近视或远视的人群,建议在佩戴有度数的泳镜时选择比平时近视低50到100度的度数。

当合并有散光时,建议将散光度数除以2,加上原有近视或远视度数,然后同样再降低50至100度左右即可。此外,若本来屈光度数就比较低(150度以下),建议直接佩戴平光游泳镜就可以了。

当然,选对了游泳镜,还应当注重对游泳镜的保养。一般在游泳镜使用后用清水清洗干净,并在阴凉处自然晾干后,放入泳镜盒内即可,不需要毛巾擦拭。注意不要将泳镜放在温度高的地方,更不要放在太阳下暴晒。
