Abstract

Lente progresiva y procedimiento y utilización correspondientes. La lente progresiva cumple unos requisitos ópticos y geométricos, que limitan las aberraciones ópticas y posicionan los valores máximos de las mismas en determinadas zonas de la lente. El procedimiento de fabricación comprende una etapa de resolución de un problema de optimización de una función vectorial, calculado numéricamente, donde la función vectorial tiene por lo menos dos componentes que incluyen el cálculo de por lo menos una integral a lo largo de toda la primera cara refractiva, de unas funciones integrando que son el producto entre el astigmatismo oblicuo a(vector x) y una función {al}(vector x), y el producto {be}(vector x)(E(p(vector x))) donde {al}(vector x) y {be}(vector x} son funciones de peso, p(vector x) es la potencia, y la función E es una función de error entre la primera cara refractiva y la distribución de potencia especificada para el diseño.Progressive lens and corresponding procedure and use. The progressive lens meets optical and geometric requirements, which limit the optical aberrations and position their maximum values in certain areas of the lens. The manufacturing process comprises a step of solving a problem of optimization of a vector function, calculated numerically, where the vector function has at least two components that include the calculation of at least one integral along the entire first face refractive, integrating functions that are the product between oblique astigmatism a (vector x) and a function {al} (vector x), and the product {be} (vector x) (E (p (vector x))) where {al} (vector x) and {be} (vector x} are weight functions, p (vector x) is the power, and function E is an error function between the first refractive face and the specified power distribution for the design
