Idaho Code § 54-1517
It shall be unlawful for any person other than a licensed optometrist or physician to accept or offer to accept for purpose of duplication any ophthalmic lens or prism ordinarily used before the human eye for corrective purposes, or for assisting vision; provided, however, that any manufacturing, dispensing or surfacing optician is hereby permitted to grind or supply, dispense, replace or duplicate any such lens in conformity with the prescription or instruction of any optometrist or physician duly licensed to practice within the state of Idaho. Contact lenses may be sold or dispensed in a retail or wholesale outlet or other permanently established place of business with an optical department only when the prescription specifically states on its face that it is intended for contact lenses and includes the type and specifications of the contact lens being prescribed.
