The possibility of using electric hydrogels as materials in lenses with variable focal length (“smart lenses”) has been investigated. The focus is on identifying and controlling parameters such as the density of the surface connection and the degree of neutralization that affects the properties of the required gel. These characteristics include optical transparency, structural strength and electrical reactivity. The transmission of an electrical signal to the gel is investigated by determining the ideal shape, location, and material for the electrodes used in Smart Lens applications. Types of materials are tested with mixed results, and suitable electrode materials are recommended. The structural and optical properties of the gels are evaluated through swelling and optical transmissivity measurements. However, there are some apparent anomalies that are attributed to limitations in existing knowledge about gel swelling processes.
