We all know that the blue light that emits from our smartphones isn't good for our eyes, but a new study has discovered just how much damage it can cause. 我们都知道智能手机发出的蓝光对眼睛有伤害，但一项最新研究发现了这些蓝光的具体的伤害程度。 Researchers say that this light is absorbed by vital molecules in our retina and triggers the production of a toxic chemical that kill cells. 研究人员发现，视网膜上面的主要分子会吸收这些蓝光，并会产生有毒的化学物质来杀死细胞。 This damage can lead to large blind spots in our vision that are the hallmark of macular degeneration, a disease that leads to blindness. 这种伤害可导致视力出现大面积盲点，也就是黄斑病变的典型特征。这种疾病最终会导致失明。 The team from the University of Toledo in Ohio says it is urging the public to not use phones in the dark because this can dilate pupils and lead to even more harmful blue light entering our eyes. 来自俄亥俄托莱多大学的研究小组，呼吁公众不要在暗处使用手机，这样会导致瞳孔放大，而且导致更多蓝光进入我们的眼睛。 Age-related macular degeneration (AMD) is the leading cause of vision loss for those age 50 or older, according to the National Eye Institute. 国立眼科研究所的数据表示，由于黄斑病变导致视力减弱的主要是50岁及以上的人群。 |
