Achromatopsia

Achromatopsia is a rare genetic condition where individuals experience complete color blindness, seeing the world in shades of gray. It also typically causes very poor vision in bright light (photophobia), decreased sharpness (visual acuity), and an inability to see detail clearly. Since color perception relies on specialized cells in the eye called cones, achromatopsia results from their malfunction or absence. Affected individuals often use low vision aids, and while their condition is stable, it significantly impacts daily life due to limited visual and color perception.
