|(a) To protect the public health and provide a means for the patient to identify a licensee in a complaint filed with the Board, §351.362 of the Act requires an optometrist or therapeutic optometrist to display the doctor's name so that the name is visible to the public before entry into the office reception area. This requirement does not apply to an optometrist or therapeutic optometrist practicing at a location on a temporary basis, as defined in subsection (b) of this section. (b) Temporary basis is defined as the practice of optometry or therapeutic optometry at an office for no more than two consecutive months. For example, an optometrist or therapeutic optometrist practicing at a location one day per week during a three month period is not at that location on a temporary basis, and the doctor's name must be displayed as required in §351.362 of the Act. (c) Section 351.458 of the Act prohibits the display of an optometrist or therapeutic optometrist's professional designation if the intent of the display is to mislead the public that the named optometrist or therapeutic optometrist owner regularly practices at that location. Therefore an optometrist or therapeutic optometrist practicing at an office in which the doctor has no ownership interest, must display the doctor's name as licensed by the Board, regardless of the percentage of time spent at that office, unless the doctor's practice meets the definition of temporary basis in subsection (b) of this section.
