The eyes provide rich physiological and broad diagnostic information, making contact lens sensors a promising disease diagnostic tool. A smart contact lens, one such contact lens sensor, can quantify the concentrations of various biomolecules and electrolytes in ocular fluids and physical biomarkers of the eye, such as intraocular pressure (IOP). Continuous and non- or minimally invasive contact lens sensors can be directly utilized in a clinical or point-of-care setting. Here, we introduce the incorporation of contact lens sensors and their fabrication, sensitivity, power source, and readout mechanisms. The incorporation is to monitor glaucoma and conditions associated with eye health, such as dry eye syndrome and inflammation. The contact lens sensors fit seamlessly across different corneal curvatures and thicknesses in human eyes. The lens can also wirelessly capture the intraocular pressure by utilizing the principle of the mechanical deformation of the microfluidic channel under ambulatory conditions. Also, we will discuss the colorimetric ocular electrolyte tear fluid sensor to detect the color change of dry eye disease and inflammation. We assessed the in vitro biocompatibility, ex vivo functionality, and in vivo safety of the soft contact lens sensor.
