Optometrist vs. Ophthalmologist vs. Optician: Which Eye Doctor Do You Need?
Optometrist, ophthalmologist, or optician — what's the difference, and who should you see? A plain-language guide.
Table of Contents
Short answer: For a routine eye exam, a new prescription, dry eye care, diagnosing and treating eye dieseas or children's vision, you want an optometrist. An ophthalmologist is a medical/surgical eye doctor you're usually referred to for surgery or complex disease cases requiring subspecialty training. An optician fits and dispenses the glasses and contacts your prescription calls for. Most people's eye care starts, and stays, with an optometrist, the point of entry for vision care in Canada.
What does an optometrist do?
An optometrist (OD) is a primary eye care provider. They perform comprehensive eye exams, prescribe glasses and contact lenses, diagnose and manage conditions like dry eye, glaucoma, cataracts, macular degeneration and diabetic eye changes, and handle many urgent eye problems. In Ontario, optometrists are who most people see first, and for the great majority of eye care needs, the only provider you'll need. Our optometrists at Vision Care Ottawa cover exams, dry eye treatment, children's vision, myopia control, and contact lenses across three clinics.
What does an ophthalmologist do?
An ophthalmologist is a medical doctor (MD) who specializes in eyes and can perform eye surgery such as cataract removal, LASIK, retinal procedures, and treatment of complex or advanced disease. You typically see one by referral, often from your optometrist, when a condition needs surgical or specialized medical management. Think of it as the specialist layer above primary eye care.
What does an optician do?
An optician fits, measures, supplies, and adjusts eyewear based on a prescription from an optometrist or ophthalmologist. They're the experts in lenses, coatings, and frame fit, but they don't examine your eyes or write prescriptions.
So who should you see?
- Due for an exam, blurry vision, new glasses or contacts, dry or irritated eyes, a child's first exam? → Optometrist.
- Been referred for surgery, or managing advanced disease? → Ophthalmologist.
- Have a current prescription and just need the right eyewear? → Optician (we have opticians on-site).
The good news: starting with an optometrist means you'll be pointed to exactly the right care if you ever need a specialist.
