(a) If the board has reason to believe that an optometrist is impaired, the board may cause an evaluation of the optometrist to be conducted for the purpose of determining if there is an impairment, and may suspend or restrict the license of any optometrist who declines to submit to and cooperate with such evaluation.
(b) If the board finds, after evaluation and a due process hearing held under rules of procedure to be established by the board, that a licensee is impaired, the board may take action as allowed by this article.
