Special contact lenses will let monitoring progression of eye diseases.

Scientists from Purdue University have unveiled a technology that 'pumps' conventional soft contact lenses and turns them into a device for assessing the condition of the eye and the course of ophthalmic diseases, including glaucoma.

According to Medicalxpress.com, this is a technology for seamlessly integrating ultra-thin sensors into commercially available soft contact lenses using the wet bonding method.

Built-in sensors record the electrophysiological activity of the retina by reading signals from the surface of the cornea.

Local anesthesia is not required for measurements.
