随着年龄的增长，我们的眼睛不再像小时候那么明亮，因为我们的眼睛比身体其他器官衰老得都要快。新研究发现，每天凝视红光3分钟可以有效改善视力，而且年长者的效果尤为显著。

A few minutes of looking into a deep red light could have a dramatic effect on preventing eyesight decline as we age, according to a new study published this week in The Journals of Gerontology.

根据本周发表在《老年学杂志》上的一项新研究，只要凝视深红色光几分钟，就能有效地预防视力衰退。

"You don't need to use it for very long to start getting a strong result," said lead author Glen Jeffery, a professor of neuroscience at University College London's Institute of Ophthalmology.

该研究的首席作者、伦敦大学学院眼科研究所神经科学系教授格伦·杰弗瑞说：“你不用看很长时间红光，就能有立竿见影的效果。”

The science works, Jeffery said, because the light stimulates the health of mitochondria, which are like batteries in our cells.

杰弗瑞说，其科学原理在于红光可以增进线粒体的健康，线粒体就像我们身体细胞的电池。

mitochondria[ˌmaɪto'kɑndrɪr]: n. 线粒体

And because mitochondria are implicated in a broad range of diseases, insights like these could help lead to new treatments for diseases including Parkinson's and diabetes.
