Optometry Schools and Colleges. Doctors of Optometry (O.D.s/optometrists) are the independent 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 is a doctor of optometry (OD) who is trained in the study of vision. The optometrist performs routine eye care, conducts eye examinations and prescribes corrective lenses. Optometrists also diagnose and prescribe treatment for eye diseases. Treatment may include medication in the form of drops, pills or injections.
