Ophthalmologist,” “optician,” and “optometrist” are terms often confused when discussing eye care professionals. Each refers to a different role in eye care. An “ophthalmologist” is a medical doctor who specializes in eye diseases and surgeries. An “optician” is trained to make and sell glasses or optical equipment, while an “optometrist” examines vision and prescribes corrective lenses. This lesson will explain the distinctions between these roles with examples.

Ophthalmologist

Definition:

An “ophthalmologist” is a medical doctor (M.D.) who specializes in diagnosing and treating eye diseases, performing surgeries, and providing overall eye care.

Examples of use:

The ophthalmologist diagnosed Sarah with glaucoma and recommended immediate treatment.

After experiencing severe vision problems, Mark consulted an ophthalmologist who performed cataract surgery.

Ophthalmologists can perform complex procedures such as retinal surgery or laser eye surgery.

Optician

Definition:

An “optician” is a technician who is trained to make and fit glasses and contact lenses based on the prescriptions provided by optometrists and ophthalmologists.

Examples of use:

The optician helped me choose the right frames for my new glasses.

After receiving her prescription, Emma went to the optician to have her lenses made.

Opticians also assist in repairing or adjusting glasses for better fit and comfort.

Optometrist

Definition:

An “optometrist” is a healthcare professional who examines the eyes, tests vision, and prescribes corrective lenses, but is not a medical doctor.

Examples of use:

The optometrist performed a thorough eye exam and prescribed new contact lenses for me.

Optometrists can diagnose common vision issues like nearsightedness or astigmatism.

My annual vision check-up is done by an optometrist who ensures that my prescription is still accurate.


An “ophthalmologist” is a medical doctor specializing in eye diseases and surgeries, an “optician” makes and sells optical equipment like glasses, and an “optometrist” examines vision and prescribes corrective lenses. Knowing the differences among these professionals will help you seek the right type of eye care.
