A Contact Lens Interface
​

Millions of people use contact lenses daily with comfort and without any adverse effect. When a collection of sensors are incorporated in the structure of the contacts lens, an unparalleled opportunity arises for continuous healthcare monitoring. The surface of the human eye (the surface of the cornea) is covered by live cells in indirect contact with the blood serum; hence, many of the biomarkers of interest that appear in a blood sample are also reflected in the biochemical composition of the fluid directly on the surface of cornea. If a device can be made to continuously sample and analyze the biochemical make up of the eye surface, in effect a blood test can be performed without collecting a blood sample.
