Optometrists are trained to diagnose and treat vision conditions like nearsightedness, farsightedness, and astigmatism. They are trained in prescribing eyeglasses, contact lenses, eye exercises, low vision aids and vision therapy. They are also trained to identify cataracts, glaucoma, and retinal disease and to use some medications to treat eye disease.
Optometrists do not attend medical school. Most complete an undergraduate degree before beginning four years of training for an optometry (OD) degree; doctorate of optometry. Some complete a postgraduate one-year clinical residency to gain specialist certification.
The services optometrists provide include:
Optometrists may also take part in preoperative and postoperative care for patients having eye surgery.
Optometrists and ophthalmologists may work in the same office and co-manage patients.
