高端诊所解答:在昏暗的灯光下阅读会损伤眼睛?

作者: webmaster   浏览量:326  发布时间:2020-04-17

高端诊所小编如果没猜错的话,在成长过程中,你的父母可能对你说过,别老看电视,要吃干净盘里的蔬菜,不然眼睛会看不见。但这些话有多少是真的?还有多少与眼睛有关的传言呢?


在昏暗的灯光下阅读会损伤眼睛?
真假?其实真假参半
当你蒙着被子阅读时,父母可能告诉过你要关灯睡觉,还警告说这样很伤眼睛。他们说的是真的吗?
有真有假。人眼的设计很精妙,可以适应不同的光线。如果你在昏暗的灯光下阅读,瞳孔会暂时变大,这样视网膜就会接受更多的光。然后,视杆细胞和视锥细胞将通过光线向大脑发送阅读信息 - 书籍或杂志。一段时间后,有的人会出现眼疲劳,有的人不会。
在进行具有挑战性的视觉活动时,例如在光线不足的情况下阅读,除了出现眼疲劳外,如果眨眼频率低,眼睛也会暂时发干。虽然会不舒服,但不会损害眼睛的结构或功能,可以使用眼睛润滑液缓解。


昏暗光线下阅读会造成怎样的长期影响?关于这方面的深入研究并不多,但有些研究针对的是经常近距离盯着东西看所造成的影响。经百汇中国检测结果表明,这种“近距离工作”可以加速儿童近视眼的发生。因此,如果你在昏暗的灯光下阅读,并且眼睛离书很近,这通常会对视力造成损害,但偶尔这样一般是不会有事的。
