This is an NPI-based check only. NPISignal does not publish name-based exclusion matches on a provider profile. A shared or similar name is a lead that requires human review, not an identification, and this page is not the place to make one. Run a name-based screening below to see potential matches with the reasons for each.

Specialties & Taxonomies

  • Optometrist

    Eye and Vision Services Providers

    Primary

    Doctors of optometry (ODs) are the primary health care professionals for the eye. Optometrists examine, diagnose, treat, and manage diseases, injuries, and disorders of the visual system, the eye, and associated structures as well as identify related systemic conditions affecting the eye. An optometrist has completed pre-professional undergraduate education in a college or university and four years of professional education at a college of optometry, leading to the doctor of optometry (O.D.) degree. Some optometrists complete an optional residency in a specific area of practice. Optometrists are eye health care professionals state-licensed to diagnose and treat diseases and disorders of the eye and visual system.
