S.C. Code Ann. § 40-38-270

Notwithstanding any other provision of law, with respect to contact lenses, an optician shall act upon receipt of and based on a prescription for the lenses by an ophthalmologist or optometrist. Nothing in this chapter may be construed to allow an optician to fit contact lenses or to make professional determinations as lenses to the specifications of these lenses unless under the supervision of an ophthalmologist or optometrist. If supervision is not direct and if the optician dispenses the contact lenses outside of the presence of the ophthalmologist or optometrist, the optician shall instruct the patient to return to the prescribing ophthalmologist or optometrist for verification of the fitting as soon as an appointment may be obtained.
