【英语阅读】危险，手机蓝光伤害很大。

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，但一项最新研究解释了蓝光能造成的伤害程度。

 Researchers say that this light is absorbed by vital molecules in our retina and triggers the production of a toxic chemical that kill cells.

研究人员说，这种光被我们视网膜中的重要分子吸收，并触发产生杀死细胞的有毒化学物质。

 This damage can lead to large blind spots in our vision that are the hallmark of macular degeneration, a disease that leads to blindness.

这种损伤可导致我们视力中的大盲点，这是导致失明的黄斑变性的标志。

 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.

来自俄亥俄州托莱多大学的团队表示，它正在敦促公众不要在黑暗中使用手机，因为这会扩大瞳孔并导致更有害的蓝光进入我们的眼睛。

 Age-related macular degeneration (AMD) is the leading cause of vision loss for those aged 50 or older, according to the National Eye Institute.

根据国家眼科研究所的数据，年龄相关性黄斑变性（AMD）是50岁或以上老年人视力丧失的主要原因。

The condition occurs when the macula, an oval area near the center of the retina that allows for sharp vision, becomes damaged.

当黄斑（视网膜中心附近的椭圆形区域允许清晰视觉）受损时，就会发生这种情况。

 Sufferers will experience blurred vision or even 'blind spots' in their central vision that may grow larger as the retina dies.

患者的中心视力会出现视力模糊甚至“盲点”，视网膜死亡时可能会变大。
