What is a Doctor of Optometry?

A Doctor of Optometry (O.D.) is an independent primary health care provider who examines, diagnoses, treats, and manages diseases and disorders of the entire visual system.  The services rendered by optometrists include: prescribing glasses and contact lenses, rehabilitation of the visually impaired, diagnosis and treatment of ocular disease.  Optometrists can practice in a variety of settings:

  • Solo or group practice
  • Hospitals, clinics, and community health centers
  • Public health
  • Military
  • Government

Within these settings, optometrists engage in primary care practice or they can specialize in an area such as pediatrics, geriatrics, occupational vision, low-vision services (for the visually impaired), or sports vision.  Optometrists do not perform surgery nor prescribe medication.


There are currently 20 schools and colleges of optometry in the US (plus two in Canada and one in Puerto Rico) offering an OD degree. The four-year OD curriculum begins with two years of classroom and laboratory work in the basic sciences. The remaining two years are comprised primarily of supervised patient care in hospitals, private practices, and clinics. Upon completion of the program, an OD is qualified to seek appropriate state licensure.

Admissions Requirements

Admissions requirements can vary from school to school, Generally, OD programs expect a BA or BS with an undergraduate curriculum similar to the following:

1 year Chemistry with lab CHEM 403-404
1 year Physics with lab PHYS 401-402 or PHYS 407-408
1 semester Organic Chemistry

CHEM 545/546

1 semester Biochemistry BMCB 658/659

Some programs require anatomy and physiology, a full year of organic chemistry, or additional coursework in the humanities or social sciences, so plan to check with individual schools of interest. An applicant’s undergraduate major is not a factor in admission, so students may complete these prerequisites as major requirements, general education requirements, or as electives.

Students should consult the Schools and Colleges of Optometry Admissions Requirements directory, found at The Association of Schools and Colleges of Optometry (ASCO), to determine the specific requirements of the programs they are interested in.

Application Process 

OD programs require that applicants take the OAT (Optometry Admission Test), which is offered throughout the year.  OptomCAS is the central application service for OD programs. Programs use a rolling admissions process and students are advised to apply as early in the process as possible.
