What Do Optometrists Do?

Optometrists examine the internal and external structure of the eyes to diagnose eye diseases such as glaucoma, cataracts and retinal disorders; systemic diseases such as hypertension and diabetes; and vision conditions including nearsightedness, farsightedness, astigmatism and presbyopia. During an examination, optometrists conduct and assess:

  • Vision assessments/refraction
    Optometrists determine the clarity or blur that patients have and use tailored techniques to find a prescription for the patients best possible vision. 
  • Binocular vision
    Optometrists determine the patient’s ability to properly focus and coordinate the eyes, and assess depth perception. 
  • Eye disease
    Optometrists diagnose and treat some eye diseases with pharmaceutical agents. They also identify systemic diseases with ocular manifestations such as diabetes, high blood pressure, thyroid conditions, cancer, and HIV. 
  • Pre/post-op care
    Optometrists provide both pre-operative and post-operative care for cataract surgery, refractive surgery (LASIK), and retinal surgery.
