When your vision changes or your eyes feel uncomfortable, it can be confusing to know which eye-care provider to see. Should you book with an optometrist, an ophthalmologist, or an optician? Each plays a different role, and understanding the differences helps you make the best choice for your eye health.
At Northern Sight Optometry, we want our Kleinburg–Vaughan patients to feel confident, informed, and fully supported. Here’s a simple, easy-to-read guide to help you understand how these professionals work together to keep your eyes healthy.
Optometrists: Your Primary Eye Care Doctors
An optometrist (OD) is your first stop for most eye and vision concerns. Optometrists complete years of university and four years of clinical training focused on the eyes, visual development, and the eye–brain connection. They also often complete subspecialty residency training.
Optometrists provide:
Comprehensive eye exams to check your prescription and overall eye health
Medical eye care for problems like dry eye, eye infections, allergies, and injuries
Detection and management of chronic eye diseases such as glaucoma, macular degeneration, and diabetic eye disease
Pediatric eye exams and support for children’s visual development
Vision correction solutions including glasses, contact lenses, specialty lenses, and myopia management
Think of your optometrist as the family doctor for your eyes. They diagnose eye conditions, treat most vision problems, and refer you to an ophthalmologist if you need surgical care. For routine eye exams, checking a prescription, managing eye discomfort, or investigating symptoms, an optometrist is the right place to start.
Ophthalmologists: The Eye Surgeons
An ophthalmologist is a medical doctor (MD or DO) who specializes in eye surgery and advanced eye disease management. They complete medical school, an ophthalmology residency, and often subspecialty fellowship training.
Ophthalmologists focus on:
Eye surgeries such as cataract removal, LASIK, retinal surgery, or corneal transplants
Advanced treatment for complex glaucoma, retinal disorders, or eye trauma
Medical procedures like injections for macular degeneration or surgical repair after injury
In short, if your eye condition requires surgery or complex medical treatment, your optometrist will refer you to an ophthalmologist.
Opticians: The Eyewear Experts
An optician is a trained eyewear professional who helps you choose and properly fit your glasses based on your prescription.
Opticians specialize in:
Frame selection that fits your style, comfort, and face shape
Lens customization including progressives, blue-light protection, anti-glare coatings, and more
Glasses adjustments and repairs to ensure your eyewear fits comfortably and performs well
Opticians do not perform eye exams or diagnose eye problems — but they play an essential role in helping you see clearly and comfortably with your prescription lenses.
Who Should You See First?
Start with your optometrist for routine eye exams, prescriptions, and medical eye concerns. Many eye diseases are silent at first — meaning you may not notice symptoms until damage has occurred. Routine exams help detect problems early and protect your vision long-term.
Visit an optician to select and fit glasses once your prescription is finalized. Get referred to an ophthalmologist only if you need surgery or advanced treatment.
At Northern Sight Optometry, we provide full-scope care for Kleinburg–Vaughan families, from children’s eye exams to digital eye strain solutions, dry eye treatment, and management of chronic eye conditions.
