Just read this essay by Olivia Laing in her book "Funny Weather: Art in an Emergency"about the painter Sargy Mann. He progressively lost his sight towards the end of his life, and when he couldn't barely see anymore he produced these beautiful set of paintings of people in between leaving the pool and going inside this little sitting room. His debilitated sight made him focus a lot more on the blocks of colour, that are so vibrant they scream on the paintings, even when seeing them through a computer screen.
