Any person formerly licensed to practice optometry in this state, who receives notification from the Board that the person's license to practice optometry has expired for failure to pay the annual renewal fee, shall within 10 days of receipt of such notification from the Board either pay the applicable renewal fee or surrender the license by mailing or otherwise delivering such license to the Board office. Alternatively, rather than physically surrender the license, the person may file with the Board an affidavit in the form acceptable to the Executive Director to the effect that such person is not practicing and will not practice optometry.
