Abstract

Optómetro y procedimiento para determinar las dioptrías necesarias para mejorar la visión.#Optómetro y procedimiento para el cálculo de dioptrías necesario para mejorar la visión nocturna. El optómetro comprende una fuente de luz puntual, un objeto que comprende un difusor iluminado en forma de polígono y una abertura con forma correspondiente al polígono, un ocular, una lente situada entre el ocular y el objeto y medios para desplazar el conjunto formado por la fuente de luz puntual y el objeto. Mediante el cálculo de las distancias a las que el sujeto ve nítidamente un objeto difusor que le permite acomodar y una abertura con una forma correspondiente es posible de manera sencilla y rápida calcular las dioptrías necesarias para mejorar la visión nocturna.Optometer and procedure to determine the diopters necessary to improve vision # Optometer and procedure to calculate diopters necessary to improve night vision. The optometer comprises a point light source, an object comprising an illuminated diffuser in the shape of a polygon and an opening shaped corresponding to the polygon, an eyepiece, a lens located between the eyepiece and the object and means for moving the assembly formed by the Point light source and object. By calculating the distances at which the subject clearly sees a diffuser object that allows it to accommodate and an opening with a corresponding shape it is possible to quickly and easily calculate the diopters necessary to improve night vision.
