Optometrists also test for glaucoma and other eye diseases, and diagnose conditions caused by systemic diseases, such as diabetes and high blood pressure, referring patients to other health practitioners, as needed.
An optometrist earns a Doctor of Optometry degree but is not a medical doctor, according to the AAPOS. Like ophthalmologists, optometrists are licensed by the state. They perform routine eye exams, prescribe eyeglasses and contact lenses, and treat certain eye conditions and diseases.
