What is blue cone monochromacy?

Blue cone monochromacy is a rare genetic X-linked retinal disorder that results in a person having only S cones and missing L and M cones. Because the brain must compare input from at least two types of cones to detect color, people who have only functional S cones have very poor color vision.
