Thank you for shopping locally and supporting small business. Your investment in your eye exam, contact lenses and glasses are also going to the city to help build communities and roads in Markham. They are going to York Regions for education funds in the region, and also going towards hiring local staff that would help in raising their children and covering daycare. Please note that there are no refunds. We have prescription guarantee for first two months. You are welcome to take a copy of your glasses prescription after each full eye exam. Your Markham eye doctor and Optometrist, Yan Ling Liang.
