Caring for Our Community

At Lowy & Sewell Eye Care, our dedicated team of optometrists and eye care professionals focus on more than just your eyes. Caring for our patients means looking at how your vision and eye health impact your quality of life. 

When you visit us, it’s more than routine. We’ve served generations of families and love getting to know our patients. Our comprehensive approach considers your wellbeing, whether you’re stopping by for a new pair of stylish glasses or need support managing your child’s myopia.

We see patients from Thornhill, Bathurst Manor, North York, University Heights, and neighbouring communities. We look forward to seeing you and your family.
