Our Eye Doctors

Eye care professionals specialize in understanding how the human eye really works, as well as diseases and conditions that affect your vision – many of which do not have obvious symptoms. Eye doctors know how age and risk factors affect vision over time for young and old, and they understand the benefits and features of corrective lenses including eyeglasses and contacts.

Our optometrists take the time to explain the results of your eye exam, describe your options and listen to your eye care needs. Because maintaining good eye health is an ongoing partnership, we encourage you to ask questions and share your health information, which could be vital to monitoring, diagnosing and treating potential vision problems.

Meet our doctors:

She was then accepted into a residency program at the Illinois College of Optometry in Chicago where she specialised in Primary Eye Care and Ocular Disease.

She moved to beautiful Victoria in 2003 where she began practising at Peninsula Lifetime Eyecare Centre and partnered into the practice in 2008.

Dr. Andrew Lewis

Dr. Lewis could not be more excited about returning to Vancouver Island, a place he has long considered home. When not working he enjoys playing hockey, soccer and practically anything outdoors. Dr. Lewis is honoured to be joining the impressive team at Peninsula Lifetime Eyecare. He looks forward to meeting you, and providing unique solutions to meet your specific visual needs.
