The eyes can provide rich physiological information and offer broad diagnostic potential as a sensing site, making the use of contact lens sensors viable for noninvasive monitoring of many diseases and conditions. Therefore, extensive research efforts recently are devoted to the development of smart contact lenses for healthcare monitoring. Herein, physical biomarkers, which can be obtained from the eyes, and chemical biomarkers, which can be obtained from tears are discussed. Then, the latest advances in smart contact lenses with biosensors that diagnose diseases are reviewed. The subsequent content summarizes and classifies the techniques that can be used for the transmission of data based on the methods to deliver physiological information. In addition, representative examples of other devices for drug delivery energy storage are provided, and the challenges that should be overcome to develop smart contact lenses are discussed.
