Claude Monet was a French painter and founder of the impressionist movement. The signature characteristic of Claude Monet’s work was the use of light and it featured prominently in many of his landscapes.
In 1923 Claude Monet had eye surgery to remove cataracts. These cataracts had affected Monet’s work, causing a reddish tone in many of his paintings. After this surgery Monet was able to see ultraviolet wavelengths normally filtered by the lens of the eye! Some believe this extraordinary vision was responsible for the striking presentation of color demonstrated in his later works.
