Four types of professionals can provide eye care services:
- Physicians (M.D.) can perform eye exams (including checking for eye diseases), provide eye care and treatment, and prescribe and dispense glasses and contact lenses.
- Optometrists (O.D.) can perform eye exams to determine the need for glasses, and prescribe and dispense glasses and contact lenses and low-vision devices.
- Opticians can dispense glasses, contact lenses, and optical supplies that are prescribed by a physician or optometrist.
- Ocularists can dispense artificial eyes.
