在强光下看书为什么不好?
在强光下看书不好主要是因为光线过强会导致眼睛疲劳、眩光影响视线以及可能造成眼底损伤，具体如下：
1、光线过强会导致眼睛疲劳：在强光下，眼睛为了适应过强的光线，瞳孔会缩小，眼睛的调节负担加重，容易导致眼睛疲劳、酸胀，长期下来可能会造成视力下降。
2、眩光影响视线：强光会在书页上产生反射，形成眩光，干扰视线，使得阅读变得更加困难，眼睛需要不断地调整焦距来适应，容易导致视疲劳。
3、可能造成眼底损伤：长时间暴露在强光下，可能会对视网膜造成损伤，尤其是紫外线等短波光线，可能会增加患白内障、黄斑变性等眼病的风险。
总结：在强光下看书不好主要是因为光线过强会导致眼睛疲劳、眩光影响视线以及可能造成眼底损伤。
