Color vision detecting and correcting method and equipment and its application

Abstract

The color vision detecting and correction method incldues the steps of: displaying several sets of achromatopsia detecting charts corresponding to one type of achromatopsia each for the testee to distinguish and determining the achromatopsia type of the testee; displaying at least one colour matching comparision diagram in one area for displaying some preset color and one other area for the testee to match color; receiving the color matching result of the testee; comparing the said color matching result with the preset color to determine the achromatopsia grade of the testee; and selecting corresponding achromatopsia correcting spectral curve based on the achromatopsia type and grade. One achromatopsia detecting / correcting equipment is also disclosed.

Description

technical field [0001] The invention relates to a color vision detection / correction method and equipment for detecting color blindness types and steps, and an application thereof in color blindness correction. Background technique [0002] Abnormal color vision, commonly known as color blindness, is a hereditary physiological defect. We know that the human brain uses the inherent three-dimensional color coordinates to define the color according to the size and direction of the sum of the received three primary colors red (R), green (G), and blue (B) vectors, and produces color vision. If there is a variation in a certain level of the color vision process, the proportion of the three primary color vectors received by the brain will be out of balance. However, the brain still produces color vision according to the inherent color definition, which will inevitably lead to abnormal color vision and color blindness. (See "Introduction to Color Vision Correction", Chen Xiaoguang,...

Problems solved by technology

However, there are also the following disadvantages: since the detection / correction process using the detection equipment requires the detected person to identify, and the clearer the better, it is easy to cause the detected person to have a rebellious psychology

As a result, it leads to overcorrection and becomes another kind of color blindness. Although the color blindness can pass the color vision test after wearing corrective glasses, it cannot achieve the purpose of real correction, and still cannot recognize colors like normal people.
