Abstract:
(EN) Finished ophthalmic lens and corresponding methods. Finished ophthalmic lens that has a concave face and a convex face and an external perimeter (1) and that furthermore has: a thickness within a pre-established range; a central working area (3) that complies with a specific pre-established ophthalmic prescription, defined by a machined surface, and which has a working perimeter (5) that coincides with the perimeter of a specific pre-established frame; and an outer, transition area that connects the working perimeter (5) of the central working area (3) to the outer perimeter (1). The transition area (7) comprises a transition surface that extends as a continuation of the machined surface and extends as far as the outer perimeter (1) and is continuous, and the derivative thereof is continuous at all the points thereof, including the line connecting between the transition surface and the machined surface.
(FR) L'invention concerne une lentille ophtalmique finie et des procédés correspondants. La lentille ophtalmique finie présente une face concave et une face convexe ainsi qu'un périmètre externe (1) et présente, en outre: une épaisseur comprise dans une plage préétablie; une zone centrale utile (3) qui satisfait une prescription ophtalmique déterminée préétablie, qui définit une surface mécanisée, et qui présente un périmètre utile (5) coïncidant avec le périmètre d'une monture déterminée préétablie; et une zone extérieure de transition qui relie le périmètre utile (5) de la zone centrale utile (3) et le périmètre externe (1). La zone de transition (7) comprend une surface de transition qui s'étend comme une continuation de la surface mécanisée et s'étend jusqu'au périmètre externe (1), et est continue et sa dérivée est continue au niveau de tous ses points, y compris de la ligne de liaison entre la surface de transition et la surface mécanisée.
(ES) Lente oftálmica acabada y procedimientos correspondientes. Lente oftálmica acabada que tiene una cara cóncava y una cara convexa y un perímetro externo (1) y que tiene, además: un espesor dentro de un rango preestablecido; una zona central útil (3) que cumple con una prescripción oftálmica determinada preestablecida, que define una superficie mecanizada, y que tiene un perímetro útil (5) que coincide con el perímetro de una montura determinada preestablecida; y una zona exterior de transición que une el perímetro útil (5) de la zona central útil (3) con el perímetro externo (1). La zona de transición (7) comprende una superficie de transición que se extiende como una continuación de la superficie mecanizada y se extiende hasta el perímetro externo (1 ), y es continua y su derivada es continua en todos sus puntos, incluyendo la línea de unión entre la superficie de transición y la superficie mecanizada.
