Day Blindness
Achromatopsia is a progressive, non painful disorder of the retina that affects color vision and light perception. Cone cells not only register color, they allow the dog to adjust their eyes to bright light. Dogs with this disease constantly feel like us when we step out of a movie theater. Night vision remains completely unaffected.
