Optometrist Optometrists, or doctors of optometry (OD), provide services to evaluate, improve and preserve vision. They diagnose and treat conditions and diseases of the human eye and, depending on their diagnosis, may prescribe therapeutic medication, visual training, corrective eyeglasses, contact lenses or other visual aids. They examine the internal and external structure of the eye, evaluate vision and determine if glasses or contact lenses are needed. Like any health professional, optometrists may refer the patient to other medical specialists such as an ophthalmologist.
Optician Opticians order, prepare and fit eyeglasses and contact lenses for patients, based on a prescription from an ophthalmologist or an optometrist. Opticians grind lenses and shape them to fit an eyeglass frame and adjust the finished product to the customer. They help their customers select the best eyewear in terms of comfort, usefulness, and appearance. Opticians also repair eyewear and replace lost or damaged lenses or parts.
Ophthalmic Medical Assistant Ophthalmic medical assistants work with ophthalmologists and optometrists to provide vision care. They work directly with patients to get information necessary for the doctor. Also, they may give eye tests, measure the eyes and help to fit the patient with glasses or contact lenses.
