Bus. & Prof. Code, § 2555.1

(a) In the discretion of the board, a certificate issued under this chapter may be suspended or revoked if an individual certificate holder or persons having any proprietary interest who will engage in dispensing operations, have been convicted of a crime substantially related to the qualifications, functions, and duties of a dispensing optician. The record of conviction or a certified copy thereof shall be conclusive evidence of the conviction.

(b) A plea or verdict of guilty or a conviction following a plea of nolo contendere made to a charge substantially related to the qualifications, functions, and duties of a dispensing optician is deemed to be a conviction within the meaning of this article. The board may order the certificate suspended or revoked, or may decline to issue a certificate, when the time for appeal has elapsed, or the judgment of conviction has been affirmed on appeal or when an order granting probation is made suspending the imposition of sentence, irrespective of a subsequent order under the provisions of Section 1203.4 of the Penal Code allowing such person to withdraw their plea of guilty and to enter a plea of not guilty, or setting aside the verdict of guilty, or dismissing the accusation, information, or indictment.

(c) The proceeding under this section shall be conducted in accordance with Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code, and the board shall have all the powers granted therein.
