Alan York, an optometrist with a practice in a building he owned at 1 Main Street in East Hampton Village and a founding member of the Jewish Center of the Hamptons, died on Nov. 29 at Southampton Hospital. He was 89.
He counted among his patients the artist Willem de Kooning, with whom he spent hours discussing the old masters while watching him paint. Understanding how de Kooning painted helped him make glasses suitable for both his close-up and faraway work.
