Abstract: Photonic crystals (PCs), consisting of periodic arrays with different refractive indices, have been widely used in the fields of energy conversion, sensing, display and anti-counterfeiting due to their attributes of regulating the transmission of lightwaves. Contact lenses (CLs), traditionally used for vision correction, show long-term wearing safety, thus providing a wearable platform for continuous ocular physiological parameters (glucose, intraocular pressure (IOP), corneal temperature, and pH value etc.) monitoring and drug delivery. In this review, PCs and CLs are introduced, and an overview of recent advances of construction strategy of structural color CLs based on PCs and their applications as ophthalmic sensors and UV protection are illustrated. Finally, the existing problems and development trends are forecasted.
