Retina color and contrast perception detection apparatus

Abstract

The invention discloses retina color and contrast perception detection apparatus. The retina color and contrast perception detection apparatus comprises detection apparatus, wherein the surface of thedetection apparatus is provided with a display screen, a vision detection module is installed inside the detection apparatus, an output end of the vision detection module is connected with a color debugging module for the combined detection of different colors in the detection, an input end of the color debugging module is also connected with a test value debugging module for adjusting color depths of the colors, the color debugging module is composed of a basic color module and a function module, the basic color module is composed of a red-green detection module, a blue-yellow detection module and a black-white detection module, and the color debugging module is mapped on the display screen. Through the design of the invention, on the basis of retaining the original detection, color weakness and color blindness of vision can be further detected during the vision detection, so that the overall functionality is improved, and at the same time the use is more convenient.

Description

technical field [0001] The invention belongs to the technical field of vision testing devices, and in particular relates to a retinal color and contrast perception detection device. Background technique [0002] Vision is the ability of the retina to distinguish images. The quality of vision is judged by the ability of the retina to distinguish images. However, when the refractive medium of the eye becomes cloudy or has refractive errors, the vision of the eye with good retinal function will still decline. Therefore, in the detection of the eye, It often needs to be detected by a special vision detection device. [0003] At present, all the eyesight test devices are purely for testing the myopia problem of glasses. They are all black and white eyesight tests, and cannot directly detect various conditions such as color blindness and color weakness. Therefore, there are relatively large limitations in use and can be improved. Space. Contents of the invention [0004] The ...

Problems solved by technology

[0004] The object of the present invention is to provide a retinal color and contrast perception detection device to solve the myopia problem that all current eye test devices are purely testing glasses in the above background technology, and they are all black and white eye tests, which cannot directly detect color blindness. As well as color weakness and other conditions to detect, so there is a big limitation in use
