A wide range of diagnostic potential exists through monitoring tears in the human eye. Continuous monitoring of chemicals, metabolites, proteins, antibodies, and other biomarkers in tears are of interest since tears are readily assessable and a less complex body fluid compared to serum or plasma. Previous attempts to integrate biosensors into contact lenses has been limited to only one or two sensors, that were externally powered and were obstacle in seeing clearly due to their non-transparent nature. Further, the non-transparent nature of associated components of the biosensors such as antenna, controller circuitry, storage system, etc. limit functionality of integrating biosensors into contact lens by blocking vision. This technology integrates transparent sensors into a contact lens to detect, for example, glucose concentrations in tear fluid. The sensor array is extremely sensitive, reliable, and reversible, and because the sensors are transparent, multiple sensors can be deposited across the field of vision on the contact lens.
