摘要
A fail-safe electro-active lens is presented in which the lens includes a substrate having a diffractive relief surface and an electro-active material in optical communication with the substrate. The electro-active material can include a nematic liquid crystal host. The refractive index of the substrate is equal to the average refractive index of the liquid crystal at a wavelength in the blue light spectrum.
