Paper Abstract

Optimization methods have long been used for computer-aided optical design. In most cases, the problems to treat are 1D. Furthermore, the number of parameters we can vary is relatively small. Ophthalmic lens design, and in particular progressive addition lens (PAL) design, is quite different from classical optical design. PAL design requires the use of nonsymmetrical diopters defined by geometrical, optical or physiological quantities calculated for each point of the lens by ray-tracing methods. The large number of parameters, the complexity of the cost function and the large number of constraints, require to implement specific descent, optimization and differentiation methods.
