Patient's Query
Hello doctor,
Can one be color blind if one has 20/20 vision?
Hello,
Welcome to icliniq.com.
Well, to your knowledge color blindness and color deficiency are two different things. You gain color vision due to cone cells in your retina. True color blinds see only black and white. They have no cones or only blue cones. This is rare, and they do not have 20/20 vision; they nearly have 20/200. Most others are color-deficient people; however, it is erroneously used as a color blind. They have either two types of cones, including the blue and all three types of cones. They see the world as colored, but they have issues with color discrimination. They can have 20/20 vision.
