Description

Método de toma de medidas para la realización de precalibrados de lentes oftálmicas.Method of taking measurements for the realization of precalibrated ophthalmic lenses.

Objeto de la invenciónObject of the invention

El objeto de la presente invención es un nuevo método para la toma de medidas para la realización de pre-calibrados de lentes oftálmicas que comprende el uso de unos medios de visualización, de tal forma que se simplifique la toma de medidas, y por tanto la decisión, para el pre-calibrado de lentes y su unión a la montura.The object of the present invention is a new method for taking measurements for the realization of pre-calibrated ophthalmic lenses comprising the use of display means, in a way that simplifies the taking of measures, and therefore the decision, for the pre-calibrated lenses and their attachment to the frame.

Antecedentes de la invenciónBackground of the invention

En la actualidad se emplean distintos sistemas para la toma de medidas necesarias en el pre-calibrado de las lentes. En el primero de estos métodos se coloca la montura directamente al paciente y se toman los centros pupilares marcando con un rotulador dichos centros ópticos sobre los talcos de la montura. Con una regla de medir, se miden las diversas cotas necesarias. Este método manual, presenta los inconvenientes de ser un proceso lento y donde existen errores de medida y transcripción.Currently different systems are used for taking necessary measures in the pre-calibrated lenses. In the first of these methods the mount is placed directly to the patient and the pupillary centers marking with a marker these optical centers on the talc of the mount. With a measuring ruler, the various dimensions necessary. This manual method presents the inconveniences of being a slow process and where there are errors of Measurement and transcription.

Este método manual puede ser sustituido por un aparato apropiado para la captura de los centros ópticos. Estos aparatos, conocidos como centradores, permiten tomar las distancias naso-pupilares del paciente. Algunos centradores avanzados permiten, además, capturar las alturas del montaje, no obstante, estos aparatos tienen un coste elevado. Por último existen aparatos trazadores que toman la forma de la montura y que permiten transmitirla al fabricante.This manual method can be replaced by a appropriate apparatus for capturing optical centers. These devices, known as centering devices, allow distances to be taken Naso-pupillary of the patient. Some centering advanced also allow to capture mounting heights, not However, these devices have a high cost. Finally there tracer devices that take the shape of the mount and allow transmit it to the manufacturer.

Para realizar el pre-calibrado es necesario conocer datos sobre la montura en que se va a montar la lente una vez pre-calibrada, y disponer de medidas de la montura y de las distancias naso-pupilares del paciente, así como de las alturas del montaje de los centros ópticos de las lentes sobre la montura. El método más comúnmente usado es el conocido como "boxing".To perform the pre-calibration it is necessary to know data about the mount on which the lens once pre-calibrated, and have measures of the mount and naso-pupillary distances of patient as well as the mounting heights of the optical centers of the lenses on the frame. The most commonly used method is the known as "boxing".
