An optometrist can also be referred to as a doctor of optometry or an OD. Optometrists provide most forms of principal vision care.

It must be noted that optometrists differ greatly from ophthalmologists and dispensing opticians.

An ophthalmologist is a physician who performs eye surgery in addition to diagnosing and treating eye diseases and
injuries. Ophthalmologists may also examine eyes and prescribe eye glasses and contact lenses.

A dispensing optician fits and adjusts eye glasses and in some cases, may fit contact lenses according to prescriptions written by an ophthalmologist or optometrist.

An optometrist may perform the following tasks and more:
  • Simple eye examinations
  • Diagnosis of vision problems
  • Diagnosis of eye diseases
  • Testing patients' visual acuity
  • Testing patients' depth and color perception
  • Testing patients' ability to focus and coordinate eyes
  • Prescribing eyeglasses and contact lenses
  • Provide vision therapy and low-vision rehabilitation
An optometrist can analyze your test results and develop a personalized treatment plan. Sometimes, drugs are administered to patients in order to aid in the diagnosis of vision ailments. Certain eye diseases also require the prescription of drugs for treatment. Both preoperative and postoperative care are provided to patients by optometrists for cataract procedures in addition to laser vision correction and other forms of eye surgery.

Optometrists can play a key role in the diagnosis of systemic diseases such as diabetes and high blood pressure. Should an optometrist ever detect such a condition, patients are referred to other health practitioners as needed.
