Abstract

A method for designing ophthalmic lenses, the method comprising calculating an effective refraction index of a lens based on a unique transmission spectrum created by at least one factor related to parameters of at least one of the lens and wavelength dependency of the index of refraction of the lens material, calculating a topography of the lens to achieve a required optical power, based on the calculated effective index of refraction and producing the lens with the calculated topography.
