Optometrists are physicians who diagnose and treat vision problems. To practice as an optometrist, you need to pass a national examination and, possibly, a state examination in order to obtain licensing. Enrolled students must learn how to examine patients, diagnose vision disorders, treat vision problems and educate patients on common eye-related concerns.
