But now U.K. researchers want to fully identify individuals based on corneal reflections.

但是现在在英国的研究人员们想要了解从角膜反射出影像的全部信息。

In severe cases, keratitis can lead to corneal scarring, vision loss and complete blindness.

在严重的情况下，角膜炎可以导致角膜瘢痕、 视力下降和完全失明。

Dry eyes can get really irritating, and could lead to corneal damage.

眼变得非常刺激，并可能导致角膜损。

Sometimes rockfish eyes will even have a crystallized appearance from corneal emphysemas, little gas bubbles that build up inside the cornea.

有时石斑鱼的角膜肿，在角膜内部生出许多小泡，这使得眼看起来很像结晶。

Suffering from severe frostbite, corneal lacerations, and hypothermia, his face was so badly frostbitten that it scarcely resembled that of even a human being.

由于严重冻、角膜裂和体温过低，他的脸严重冻，甚至几乎看不出这是人的脸。

The researchers found that volunteers could usually correctly match a person's image in a fuzzy corneal reflection with a normal headshot of that same person.

研究人员发现参与研究试验的志愿者们一般情况下都能正确地将模糊成像下的眼角膜反射影像与同一个人的头部正常头像照片匹配出来。

Sometimes an infection can be devastating, and it can completely cause the eye to scar to the point that someone might need a corneal transplant or lose vision completely.

有时，眼部感染是破坏性的，它能彻底损眼，导致患者需要接受角膜移植或者彻底失去视力。

Your eyeball. Breathes. There’s not a lot of oxygen in tears, but it’s just enough to give the corneal cells what they need to stay alive so the whole sack of goo doesn’t fall apart.

你的眼球。 呼吸。 眼泪中的氧不多，但足以为角膜细胞提供维持生命所需的物质， 这样一整袋粘液就不散开。
