The Alberta College of Optometrists (ACO) Standards of Practice are established under the authority of Section 133 of the Health Professions Act.

They are considered the minimum standard of professional behavior and ethical conduct that ensures that all optometrists provide safe, competent and ethical professional services to all patients at all times. They are based on the best available and most current optometric and medical clinical evidence and research. It is incumbent upon each practitioner to exercise professional judgment when determining the current and future needs of each individual patient.

Guidelines are in constant evolution to reflect advances in optometric and medical science, certification of new competencies, development of innovative technology and updates to legislative scope of practice.
