He continued to draw even though he was blind
He was derided by reviewers later in life as if the rejection of his work by the French Academie as a whole wasn't enough. Although it may be difficult to imagine, Monet finished his final body of work when on the edge of going blind in his late 60s. Despite having cataracts that mostly obscured his sight, he was nevertheless able to capture the environment stunningly. It's sad that by the time he was 80, he was blind. He kept painting from memory, making sure that particular colors were on particular areas of his artist's palette.
An intriguing truth about Monet is that his hazy paintings were derided by the art world, who suggested that the Impressionist movement was the result of his vision issues rather than his artistic genius. His works and those of other notable artists were included in a landmark art exhibition that was dubbed "Exhibition of the Impressionists" by a critic. He was subtly implying that their artwork was incomplete and required further work. Ironically, the reviewer attacked Monet's art using a picture with the title Impression, Sunrise.
