We Can't See UV Light

Our eyes are not naturally capable of seeing UV light. People can actually see UV occasionally like after getting eye surgery because they'll replace the lens with an artificial lens that helps you focus on the image. There's this theory that Monet had because he had a cataracts later in life and he had a sort of rudimentary cataract surgery that he actually saw UV light. That's why some of his later paintings were so violent and vibrant with purples. I have this sense that we are walking around almost blind that there's so much information out there about the universe that we aren't absorbing.
