Which of the following is a ground for the denial of a license?

The conviction of a crime related to professional duties serves as a legitimate ground for the denial of a license in the field of optometry, as it directly pertains to the individual's ability to safely and ethically perform their professional responsibilities. Regulatory bodies, including those governing optometry, prioritize the protection of public health and safety. A criminal conviction can indicate a lack of good moral character or the potential for unprofessional conduct, which could jeopardize patient care and trust in the profession.

In considering this context, factors such as a history of volunteering, having a certificate of rehabilitation, or demonstrating generosity in community service do not typically disqualify an applicant from obtaining a license. In fact, these aspects often reflect positively on a person's character and commitment to their community, which can be viewed favorably during the licensure evaluation process. Therefore, the denial of a license based on a conviction related to professional duties highlights the importance placed on integrity and trustworthiness in the field of optometry.
