It's important to us that your vision is well taken care of.


This is why we have Ophthalmology, Optometry and Optical all under one roof. From eye disease treatment, regular eye exams, to finding your perfect eyewear, we are here to help.

Excellence in Eye Care Since 1989.

Dr. Jane Yang and Dr. Andrew Mah

Our practice was established in 1989 as part of a large group practice. For more than 30 years, we have been providing excellent eyecare services to the Oshawa community. In 1997, optometrist Dr. Andrew Mah became owner of this Oshawa branch. He has a vision to provide a one-stop eyecare service for patients. Dr. Mah has since then expanded the practice to include Ophthalmology, Optometry and Optical practice all under one roof, making it a well-known location for eyecare services in Oshawa. In 2022, Dr. Andrew Mah and Optician Su-Chen Mah selected the perfect person who will continue the legacy that they have worked so hard to build. They passed the torch to optometrist Dr. Jane Yang, who is passionate and knowledgeable in providing eyecare to patients.
