家长的正确指导对于青少年的用眼健康至关重要,然而不少家长却有着许多常识性的误区。作为家长的你,对于这些口口相传的误区真的全都了解吗?快来跟着视博士一起学习,给予孩子们清晰光明的未来!
1.孩子年龄还小,即使有点近视长大了就好了
假性近视确实在青少年时期普遍存在,然而等到家长察觉孩子视力出现问题才到医院进行检查时,大部分已成不可逆地变成真性近视。所以对于儿童近视,家长一定要做到尽早发现,尽早去医院进行治疗矫正,避免近视情况进一步加剧。
2.千万别给小孩戴眼镜,度数会越戴越深
研究表明:青少年近视度数发展与戴眼镜并无直接关系,而是与眼睛在发育期间眼轴增长有关。有了真性近视如果不戴眼镜会产生两种后果:一是看不清远处的目标,习惯性眯眼视物,容易造成视力疲劳;二是视物时两眼眯成一条缝,长此以往,上下眼睑压迫眼球,有可能会出现散光。视疲劳、模糊像刺激与眼肌对眼球的压迫,可能会使近视度数加深。所以戴上一副合适的眼镜,既可解决视力疲劳,又可防止度数增加过快。
3.越亮的护眼对孩子视力越好
护眼灯这一概念已经在市场普及了很多年,采用LED光源的护眼灯没有频闪,比较接近自然光的,对于视力很有益处。然而不少家长在使用过程中却有着不少误区,例如在选择台灯的亮度时,认为越亮越好。建议家长们可以选用无极调光的台灯,在使用时,如果孩子用右手写字,台灯则应该放在左边,这样不会出现局部暗区。台灯的高度应该高于孩子的头顶,这样光线的覆盖范围广,周边的明暗对比不会太强烈,孩子的使用感也会比较舒适。
4.散瞳对孩子眼睛有伤害
有家长认为散瞳验光对孩子的眼睛有伤害,还有家长认为散瞳验光后会有一段时间影响孩子视力,耽误学习,其实这些都是错误的。散瞳验光可使睫状肌调节放松,让孩子的眼睛得到充分的休息,帮助孩子排除或消除假性近视。因此,只有做了散瞳验光,眼镜度数才能配得准确。仅靠电脑验光给孩子配眼镜是不可取的,这样对孩子的眼睛有害。
5.认为配眼镜,能看清就可以了
这一条误区其实和上一条是紧密相关的,有些家长认为给孩子配了眼镜就万事大吉了,平时不注意孩子的用眼卫生,过度用眼也不干预;让孩子佩戴没有经过验光或者验光不准的眼镜;或者是一副眼镜戴很常时间都不换,这些行为都会加重孩子眼睛的负担,最终引起视力减退、视疲劳等症状。孩子近视了一定要定期进行视力检查,因为科学的医学验光配镜不仅仅是验出一个度数,而是综合考虑眼部健康、双眼平衡、眼调节功能和戴镜习惯等给出的一个合理的配镜处方和进行视功能保健的科学指导。
6.忽视户外活动的重要性
如今很多孩子整天待在室内,其实对视力很不好。在户外,自然光线的照射会使我们的身体分泌一种多巴胺,可以抑制近视的发展。此外,孩子总是待在室内,观看的东西都在眼前,会长时间处于一种“近视”的状态,对眼睛很不好
7.认为眼保健操毫无用处
做眼保健操肯定有用,它可以放松眼睛,达到缓解视疲劳的作用,但是关键在于孩子有没有按照正确的做法认真去做。许多孩子在做眼保健操的时候偷工减料,很不认真,自然也就没有什么效果。
