It shall be unlawful for any person, persons, corporation, proprietorship, partnership, or any entity other than a licensed optometrist or licensed ophthalmologist to dispense, fit, or prescribe to the public contact lenses, including FDA-approved medicated contact lenses, or any medical appliance having direct contact with the cornea of the eye. An optical dispenser may, however, fill the written contact lens prescription of a licensed optometrist or licensed ophthalmologist, provided that the optical dispenser directs the wearer of the lenses back to the prescribing optometrist or ophthalmologist for verification of the proper fit of the lenses. This section does not authorize a licensed optometrist to prescribe, fit, sell or dispense contact lenses medicated with a drug that is outside of the licensed optometrist's scope of practice.
