Achromatopsia is a very rare eye disease. The image information of the cones on the retina is not transmitted to the brain. Therefore, no colors can be recognized. Vision is severely impaired.

Symptoms and disability

In addition to complete color blindness, extreme sensitivity to light and visual impairment (visual acuity <= 0.1) are the handicaps of people with achromatopsia. Because of the strong sensitivity to glare, this congenital visual disorder is also called day blindness.
