Dr. Lou is a wonderful guy. I had been to a different optometrist before and tried four different kinds of contacts without being able to wear any of them. I finally gave up. I went to Dr. Lou for an eye exam and mentioned this during the exam. He popped contacts in my eyes and voila! Perfect. Apparently, my eyes are shaped a little different than the average person, so only some kinds will work. The previous optometrist had no idea. So, finally, at the young age of 59, I can wear contacts. Dr. Lou is a very calm and competent man and a pleasure to work with. His office is inside the Chandler Costo. You cannot go wrong with him.
