Patient's question:
University is about to graduate, and I have been looking for a job for these few months. Since I majored in science, some positions have a requirement that applicants should not be colorblind. I have never been tested before and don't know if I actually am. Could you please help me identify which two colors I can't distinguish?Doctor's answer:
Color blindness includes congenital color blindness caused by hereditary abnormalities across generations and acquired congenital color blindness due to physical diseases. Generally, it is divided into monochromacy, where a certain color cannot be identified, complete color blindness where red, blue, green, and colors cannot be distinguished, usually only black and white colors are present, or color weakness. Typically, single-roof types are not a problem, but the ability to distinguish mixed colors is relatively poor.
