Abstract
Method for determining optical equipment comprising at least one optical lens and a spectacle frame. Wearer data relating to the wearer's optical requirements, wearer's face morphology and optical equipment position on the wearer face are provided. An optical cost function is provided related to an optical function of the at least one optical lens when worn by said wearer. A light protection cost function is provided related to a spectral irradiance estimation over the wearer eye and/or wearer skin in a peri-orbital zone of the wearer eye under a given condition when said optical equipment is worn by said wearer. The optical equipment that minimizes the difference between a global cost function and a target value of the global cost function is determined, the global cost function being a function of the optical and the light protection cost functions.
