Painter, architect, and sculptor El Greco of the Spanish Renaissance (1541-1614) is believed to have had astigmatism. The artist was known for drawing elongated figures in his paintings which ophthalmologist  Germán Beritens argued in 1913 was due to his refractive condition. A more substantial example is that of Claude Monet who was diagnosed with cataracts, a condition that clouds the eyes and vision, impairs color discrimination, and impairs detail – all of which were evident in his work.
