High school students should study mathematics, chemistry and biology. A bachelor’s degree with 2-3 years of pre-optometric study is recommended at an accredited college or university. It is recommended that students take the Optometry Admissions Test (OAT) during their sophomore or junior year to gain admission into a 4-year program at an accredited optometry school*. Courses will include pharmacology, optics, vision science, biochemistry, laboratory and clinical training. Upon completion of the 4-year program, students receive their Doctor of Optometry Degree. They also must pass written and clinical state board examinations to become licensed. Optometrists wishing to specialize (see listing) must complete postgraduate residency programs. *Optometry Schools--There are no Schools of Optometry in Wisconsin.
