LASIK & Refractive Surgery

Contact Lens Solution

Contact Lens Fitting

Like Cinderella's slipper, every eye is uniquely shaped, and every contact lens is a different shape and size. A qualified optometrist will help you find the right contact lens that gives you that glasses-free lifestyle and keeps your eyes healthy.

Eyes Closed

Dry eye is a common consequence of our technologically-advanced society. When gone undetected for too long, dry eye can lead to extreme discomfort including but not limited to burning, itching, and excessive tearing. We offer advanced and individualized treatment options to alleviate your symptoms of dry eye.

Dry Eye Management

Child with Contact Lens

Myopia Management & 
Speciality Contact Lenses

When soft contact lenses just aren't for you, orthokeratology, scleral lenses, and hybrid lenses are just some of the options available to you. Specialty contact lenses correct your vision, as well as treat the consequences of modern society, from severe dry eyes to the myopia pandemic.


Emergency Eye Care

Some symptoms may require urgent attention by your eye doctor, and your needs may be accommodated as soon as possible. These symptoms may include flashes and floaters, red painful eye, ocular injury and trauma, and other symptoms that may need immediate attention.



Our general ophthalmologists are available three days a week to offer advanced diagnosis and treatment options. Referral from a family doctor or optometrist is required for an Ophthalmologist appointment.


Book an appointment with our Optometrist today if you do not have a referral.


We are passionate in finding you the perfect pair of glasses -- lenses that best fit your lifestyle and frames that speak your personality!

We offer you a whole spectrum of frames to choose from. Make an appointment with our Optician today.


About Us

Excellence in Eye Care Since 1989.


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.

Public health and global access to eye care are important issues for Dr. Yang.  She has participated in several humanitarian trips to provide eye exams, and treatment and management of eye disease to communities in need.
