Contact lenses are a successful application of biomaterials, and the chemical structure of the polymers used in contact lenses is crucial. Different types of contact lenses have been developed based on the chemical structure of polymers, considering factors like mechanical properties, optical properties, and compatibility. Advances in contact lens materials have addressed issues like oxygen permeability and biocompatibility, improving comfort and duration of use. Surface polymer modification has allowed for better long-term use and reuse of contact lenses.
Contact lenses are one of the most successful applications of biomaterials. The chemical structure of the polymers used in contact lenses plays an important role in determining the function of contact lenses. Different types of contact lenses have been developed based on the chemical structure of polymers. When designing contact lenses, materials scientists consider factors such as mechanical properties, processing properties, optical properties, histocompatibility, and antifouling properties, to ensure long-term wear with minimal discomfort. Advances in contact lens materials have addressed traditional issues such as oxygen permeability and biocompatibility, improving overall comfort, and duration of use. For example, silicone hydrogel contact lenses with high oxygen permeability were developed to extend the duration of use. In addition, controlling the surface properties of contact lenses in direct contact with the cornea tissue through surface polymer modification mimics the surface morphology of corneal tissue while maintaining the essential properties of the contact lens, a significant improvement for long-term use and reuse of contact lenses. This review presents the material science elements required for advanced contact lenses of the future and summarizes the chemical methods for achieving these goals.
