Rare Case #3 : The Ability to see UV light
In this case, we can use Claude Monet as example.
Late in his life, Claude Monet developed cataracts. As his lenses degraded, they blocked parts of the visible spectrum, and the colors he perceived grew muddy. He agreed at age 82 to have the lens of his left eye completely removed.With his lens removed, Monet continued to paint. Flowers remained one of his favorite subjects. Only now the flowers were different. When most people look at water lily flowers, they appear white. After his cataract surgery, Monet's blue-tuned pigments could grab some of the UV light bouncing off of the petals. He started to paint the flowers a whitish-blue.
I still didn't know what's this condition called, anyone?
