Dr. Leung isn't really a good optometry. He has been in thie field for over 20 years but I don't like his service. There always a long wait. The last time I went there it take about 2 hours to get my eyes check. If you know Dr. Leung pretty well he will see you before this appt. patients. He usually recommend patients to use more expensive products too. Oh, and the Dr. is kinda weird... He is always so close to you, he didn't touch you but yet seems like he is about to touch you. I don't really like the feeling.
