Researchers at Purdue University developed a soft contact lens that diagnoses and monitors eye diseases

Researchers at Purdue University in the U.S. have developed a soft contact lens that can diagnose and monitor ocular diseases in a novel, painless and unobtrusive way. The team developed the lenses by integrating ultra-thin, stretchable biosensors with soft commercial contact lenses via wet adhesive bonding. The biosensors on the lenses record retinal activity from the surface of the eye.

Zoom Out: Researchers have been trying to use commercial soft contact lenses to help diagnose and monitor eye diseases for a while, but the typical sensors and electronics used for this purpose require a hard and planar surface to function, which made them incompatible with soft contact lenses until now. Currently undergoing clinical trials, their creation can pave the way for easier diagnoses in the near future.
