Abstract

A quantitative tester of color anomalopia is composed of computer, high-performance color CRT display, standard photoelectric scaling system for human eyes, dedicated responsekeyboard, printer, light shield andmandible supporter. It has high automation level.

Description

Technical field: [0001] The invention relates to an instrument and a detection method for detecting whether the color vision of a human body is normal, and belongs to the field of medical detection equipment manufacturing. Background technique: [0002] At present, the inspection methods for abnormal color vision mainly include the color mixer test method. The working principle of this instrument is based on Rayleigh's color mixing and matching equation: red (R) + green (B) = yellow (Y), that is, red light and green light Mix and match for yellow light. The circular observation window of the abnormal color vision tester is divided into left and right half fields of view. The right half field of view directly provides yellow light with adjustable brightness (brightness); the left half field projects red light and green light at the same time. , so what is actually displayed in the left half of the field of view is a mixed color of red and green light. For people with normal...
