Blog

Most eyecare blogs are… well, boring. They read like recycled Wikipedia entries, thinly disguised textbook summaries, or clumsy ads pretending to be education. This blog is different. Here, eye health collides with physics, technology, and curiosity.

Dr. Robert Burke (optometrist and co-founder of Calgary Vision Centre) has spent over 18 years pushing the boundaries of what’s possible in eye care. Known for his obsession with optics, physics, and the math behind human vision, he brings an explorer’s mindset to every topic. Instead of repeating what’s already out there, he reframes the questions and chases the answers down unexpected paths.

This blog is where those deep dives come alive. It’s a place for people who want to understand not just what vision does, but why — and over a million readers have joined that journey so far.

If the Calgary Saddledome was made of glass

Frequently patients ask me why their glasses’ lenses are thick on some edges and thin on the other, and I typically respond that because they have astigmatism their lenses have two types of curvature on each lens, just like the Calgary Saddledome.
