A method and system for generating a three-dimensional model of a contact lens with a front and a back surface, in which the entire back surface consists of an array of independent data points shaped to conform to three-dimensional data provided by an ocular topographer. The sampling density is sufficiently high to characterize anomalies or injuries anywhere in the eye to optimize comfort and fit. The methods and systems also include modeling a scleral lens which rests either solely on the sclera, or straddles the limbus extending partially into the cornea is described. The resting surface conforms to the topology of the underlying ocular surface with topology guiding the design. Additional methods and systems model scleral lens optics without the use of trial lenses. The lens models can be used to machine or 3D print a lens that fits the patient. Such lenses benefit patients that suffer from dry eyes or whose eyes are not normally dry, but feel dry after wearing conventional contact lenses.

An additive processing method is used to produce a customized eyewear lens by selectively building layers of radiation-polymerized material onto a lens substrate that has optical power properties discernibly different from the optical properties of the customized eyewear lens. The method involves obtaining the lens substrate, calculating the modifications needed to convert the lens substrate's properties to the desired set of properties of the customized lens, generating an additive layer design to achieve the calculated modifications, and identifying at least one control point for confirmation or revision of the additive layer design. The method further involves applying liquid layers of radiation-polymerizable material to the lens substrate and irradiating the liquid layers in selected areas with controlled radiation such that the material is only polymerized and the additive layer is only formed in the select areas irradiated, according to the additive layer design.
