Smart contact lens sensor developed for point-of-care eye health monitoring

A research group led by Prof. Du Xuemin from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences has developed a "smart" contact lens that can show real-time changes in moisture and pressure by altering colors.

The "smart" contact lens can potentially be used for point-of-care (POC) diagnosis of xerophthalmia and high intraocular pressure disease.
