A contact lens that can release a drug if it detects high pressure within the eye has been created by scientists who say it could help treat glaucoma.

科学家发明了一种隐形眼镜，当它检测到眼压升高时，就会释放药物。科学家宣称这种隐性眼镜可辅助治疗青光眼。

Glaucoma is an eye disease that involves damage to the optic nerve, and can lead to blindness if left untreated.
青光眼是一种损害视神经的眼病，如不治疗可能导致失明。

The most common form of the disease, known as primary open angle glaucoma, is thought to affect almost 10% of people older than 75.
原发性开角型青光眼是最常见的一种青光眼疾病，近10%的75岁以上人群患有该眼病。

This form is generally caused by increased pressure within the eye, usually as a result of a buildup of fluid.
原发性开角型青光眼通常是由眼内压力增加引起的。眼压升高通常是由液体积聚造成的。

Researchers in China revealed they have developed a contact lens that can sense an increase in pressure within the eye and release an anti-glaucoma drug should the pressure exceed a certain level.
中国科研人员表示，他们已经研制出一种隐形眼镜，可以感知眼压的升高，并在压力超过一定水平时释放抗青光眼药物。
