A client is color blind. The nurse understands that this client has a problem with cones.
Color blindness is the reduced capacity to see color or distinctions in color. Color blindness transpires when one or more of the cone types are defective or absent. The disorder is usually inherited. Additional causes contain particular eye disorders and prescriptions. More men are affected than women.
Usually, color-blind people can not differentiate between shades of red and green. People with total color blindness (achromatopsia) may also be uncomfortable in bright conditions and have reduced visual sense.
