Abstract
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.
