I saw Dr. Wing last fall, after having a bad experience with another doctor. Dr. Wing corrected my contact prescription in an efficient manner, while still giving me plenty of attention and answering all my questions. He allowed me to have two prescription trials for one eye, so that I could decide which one I liked better (mono vision issues.). The prescription helped me see better than I had for two years. I highly recommend Dr. Wing. He was worth the long wait to get into see him.
