What visual condition does a person with achromatic vision experience?

A person with achromatic vision experiences a lack of color perception, meaning they can only see shades of gray. This condition is characterized by an inability to perceive colors due to issues with the color-detecting cells in the retina, known as cone cells. As a result, individuals with achromatic vision view the world in black, white, and various shades of gray, without the ability to discern any hues.

This understanding is crucial as it highlights how achromatic vision impacts daily life, affecting tasks that rely on color differentiation, such as selecting clothing or interpreting visual signals. Recognizing achromatic vision as solely the perception of grayscale helps clarify its distinct nature compared to other visual impairments that might allow for some color perception, albeit with difficulty.
