Optometric experience and exposure will benefit you in many ways. You must be sure that optometry is the profession for you.
Get to know the daily activities of your local optometrist. Spend time shadowing and volunteering in the optometrist's office.
Talk to your optometrist about the legal boundaries of the profession. Not all states have uniform optometric laws, so these boundaries can differ from state to state.
Gaining exposure to different modes of practice and different specialty areas within optometry would be especially helpful. The SCO admissions committee likes to see students shadowing in three or more optometry offices, preferably in different modalities. While there is no minimum number of hours of shadowing, 30 or more hours is preferred.
If you are selected for an interview, numerous questions will surround how much exposure and knowledge you already have of the profession. Be sure to detail these experiences when writing your essays for the application.
