Achromatopsia

Achromatopsia is a condition characterized by a partial or total absence of color vision

People with complete achromatopsia cannot perceive any colors; they see only black, white, and shades of gray

Achromatopsia also involves other problems with vision, such as photophobia, nystagmus, and low visual acuity

One common trait is hemeralopia (blindness in full sunlight)

There is generally no treatment to cure achromatopsia; however, dark red- or plum-colored filters can help control light sensitivity
