Description

technical field

[0001] The invention belongs to the field of medical testing equipment, and relates to a color blindness analysis instrument, in particular to a portable red-green color blindness quantitative analyzer. Background technique

[0002] Color blindness is a common eye disease, and red-green color blindness is the most common among them. In people's production and life, especially in the fields of transportation, medicine, instrumentation, textiles and fine arts, if various colors cannot be correctly distinguished, it will bring great inconvenience and even cause unnecessary losses. Therefore, color blindness detection is an inspection item in our country's routine physical examination.

[0003] At present, my country widely adopts the method of pseudo-same color map for color blindness detection, using the color blindness book as a detection tool, which can only provide qualitative inspection results, and relies on the subjective cognition of the testee for dete...
