(1) Any prescription written by a duly licensed allopathic or osteopathic physician or optometrist for any lenses, spectacles, eyeglasses, contact lenses, or other optical devices shall be kept on file for a period of 2 years with the optical establishment that fills such prescription. However, the licensed optician may maintain a copy of the prescription.
(2) Upon request by the intended user of the prescribed lenses, spectacles, eyeglasses, contact lenses, or other optical devices, or by an agent of the intended user, the optician who fills the original prescription shall duplicate, on a form prescribed by rule of the board, the original prescription. However, for medical reasons only, the prescribing allopathic or osteopathic physician or optometrist may, upon the original prescription, prohibit its duplication. Any duplication shall be considered a valid prescription to be filled for a period of 5 years from the date of the original prescription, except that a contact lens prescription shall be considered a valid prescription to be filled for a period of 2 years from the date of the original prescription.
(3) Nothing in this part shall be construed to prohibit a licensed optician from accurately duplicating lenses as to power without a prescription.
