What is Monochrome blindness?

Answer 1

Monochrome blindness, also known as total color blindness or achromatopsia, is a rare visual impairment where individuals perceive the world in shades of gray, lacking the ability to see colors. This condition arises from a malfunction or absence of cone cells in the retina that are responsible for color vision. People with monochrome blindness may also experience reduced visual acuity and sensitivity to light. Unlike typical color blindness, which affects color discrimination, monochrome blindness results in a complete absence of color perception.
