Abstract

The invention discloses a color discrimination power detection method and device, and the method comprises the steps: displaying a first preset picture according to a preset rule which comprises the steps: sequentially moving the first preset picture to different positions, obtaining the watching position of the eyeballs of a test object in the process, and then selecting a fixation position corresponding to each position of the first preset picture from each fixation position of the eyeballs of the test object, and obtaining a color discrimination power detection result of the test object according to the difference between each position of the first preset picture and the corresponding fixation position of the eyeballs of the test object. The movement track of the first preset picture position can be changed randomly, so that the test object cannot identify the picture by memorizing the movement track of the picture position, and the test object is not easy to be prompted by other people for testing, and is not easy to cheat.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a method and device for detecting color discrimination. Background technique [0002] Color discrimination, also known as "color vision", refers to the ability of the eyes to distinguish colors. Congenital color vision disorder is usually called color blindness. It cannot distinguish various colors or a certain color in the natural spectrum; and those who have poor ability to distinguish colors are called color blindness. Although color weak people can see the colors that normal people see , but the ability to recognize colors is slow or poor. When the light is low, some are almost as color blind, or show color vision fatigue. [0003] In the prior art, the method for detecting color discrimination is: the content on the color blindness test chart is judged by the test object. However, this method is easy for test subjects to cheat. Since the samples of the color blin...
