Contact Lens Database

Most lens databases are American, and a lot of what they list isn’t available here. CORE at the University of Waterloo publishes the Contact Lens Compendium ↗ for the Canadian market. Inspired by their work, we wanted something we could use mid-exam, so we built this: every lens you can get in Canada, searchable by the Rx in front of you.
