Introduction

You need an eye exam, so you search for "eye doctor near me" — and suddenly you're faced with a confusing array of titles: optometrist, ophthalmologist, optician. What's the difference? Do you need to see a specialist, or will a general eye exam suffice?

The answer depends on your specific eye care needs. This guide breaks down the key differences so you can choose the right provider.

    How They Work Together

    In Canada's eye care system, optometrists and ophthalmologists work as a team:

    1. **You see an optometrist** for your annual eye exam

    2. **The optometrist diagnoses a condition** that requires specialist care (e.g., advanced glaucoma, cataract)

    3. **The optometrist refers you to an ophthalmologist** for surgery or specialist management

    4. **The ophthalmologist performs the procedure** and may refer you back to the optometrist for follow-up care

    This collaborative model ensures you get the right level of care at each stage.


    When to See Each Provider

    See an Optometrist If:

  • You need a routine eye exam
  • You need glasses or contact lenses
  • You have dry eye or minor eye discomfort
  • You want myopia control for your child
  • You need specialty contact lens fitting
  • See an Ophthalmologist If:
