Opticians: The Eyewear Experts

Role and Responsibilities: Opticians are technicians trained to design, verify, and fit eyeglass lenses and frames, contact lenses, and other devices to correct eyesight. They use prescriptions supplied by optometrists or ophthalmologists but do not test vision or write prescriptions.

Qualifications: Typically, opticians complete a diploma or certification program and are licensed in some regions.

How to Remember: Think of “Opti-cian” as the “techni-cian” for eyewear.

Optometrists: Primary Eye Care Providers

Role and Responsibilities: Optometrists are primary health care professionals for the eye. They examine eyes for both vision and health problems, prescribe eyeglasses and contact lenses, and provide certain treatments.

Qualifications: They earn a Doctor of Optometry (OD) degree, which requires four years of postgraduate professional education.

How to Remember: “Opto-metrist” measures your “opto” (vision); they’re the ones you visit for eye exams and prescriptions.

Ophthalmologists: Medical Eye Doctors

Role and Responsibilities: Ophthalmologists are medical doctors who specialize in eye and vision care. They can diagnose and treat all eye diseases, perform eye surgery, and prescribe and fit eyeglasses and contact lenses.

Qualifications: They complete medical school plus several years of additional training in surgery and eye care.

How to Remember: “Ophthalmologist” sounds like “off-thal-mologist,” implying they offer comprehensive services, often involving surgical or medical treatment.

Key Differences

Training and Scope: The main differences lie in their training and what they can do for your eyes. Ophthalmologists have extensive medical and surgical training, optometrists focus on regular eye care and minor eye health issues, and opticians are specialized in fitting eyewear based on prescriptions.

When to Visit Each: Visit opticians for eyewear adjustments and purchases, optometrists for regular eye exams and minor eye issues, and ophthalmologists for serious eye conditions, surgeries, or complex treatments.


Remembering who does what in eye care is easier when you understand the distinct roles and training of each professional. Opticians fit your glasses, optometrists check your vision, and ophthalmologists handle complex medical and surgical eye care.
