Abstract

Progressive lens and corresponding procedure and use. The progressive lens complies with a set of optical and geometric requirements that limit sight deviations and position the maximum values of these in specific areas of the lens. The manufacturing procedure includes a phase for solving the problem of optimisation of a vectorial function, calculated numerically, in which the vectorial function has at least two components including the calculation of at least one integral along the entire refractive initial phase functions that integrate the product between oblique stigmatism alpha (F) and a function alpha (F) and the product. Beta(F)(e(p(F))) where alpha(F) and Beta(F) are weight functions, p(F) is tension, and function E is an error function between the initial refractive face and the tension distribution specified for the design.
