Optometrists have completed a Bachelor’s degree, primarily in sciences, before completing their Doctorate of Optometry degree. The doctorate is an additional four years of study including classroom and clinical education. They may do an additional year of clinical residency training. Optometrists are highly educated and clinically trained to examine and treat the eyes and visual systems of any patient, regardless of their age. Optometrists are governed by the College of Optometrists under the authority of the Regulated Health Professions Act.
