During the later part of his life, French Impressionist painter Claude Monet developed cataracts in his eyes which prevented him from seeing colors clearly. He tried various treatments to no avail. In 1923, at the age of 82, he opted to have the lens of his left eye completely removed. That's when things changed.
Judging by the paintings he produced after the procedure, it may have enabled him to see ultraviolet light. This condition is not unheard of in people with aphakia (the absence of a lens in the eye), because the lens is what prevents us from seeing light in ultraviolet wavelengths. Birds, bees, and many other animals can see UV light. So in a way, you could say Monet was half-honeybee.
