What does an Optometrist do?

Optometrists examine both the eye’s internal and external structures and diagnose eye disease, including glaucoma, retinal disorders, cataracts, systemic diseases including hypertension or diabetes, and vision conditions including astigmatism or nearsightedness. They conduct vision assessments and refraction, which determines the clarity or blur of a patient's eye. They deduce a patient's ability to focus and coordinate their eyes and their depth perception.

Optometrists prescribe corrective lenses including eyeglasses or contacts and recommend further services including low vision rehabilitation or vision therapy. If a patient requires an operation, optometrists provide preoperative and postoperative care. They take the patient’s detailed medical histories and document them, and evaluate eye-related symptoms including redness or inflammation. They advise patients about proper care and hygiene and identify health and safety factors that could impact vision, including working in front of a computer. Optometrists need a minimum state-issued license for optometry, an OD degree, and five years of experience working as an optometrist.
