(a) It is not the intent of this chapter to prevent any school teacher, welfare worker, state, county, municipality, or other public board, body, agency, institution, or official from determining in the course of their official duties the probable need of visual services; provided, that the aforenamed person or agency does not attempt to examine, diagnose, prescribe, or recommend any particular practitioner and complies with the provisions of Section 38-1-2.

(b) A license to practice optometry shall not be required for the sale, preparation, or dispensing of eyeglasses or spectacles in a retail optical dispensary or from a store, shop, or other permanently established place of business with an optical department on prescription of a duly licensed physician skilled in diseases of the eyes or a duly licensed optometrist authorized to practice under the laws of this state. Contact lenses may be sold or dispensed in a retail optical dispensary or other permanently established place of business with an optical department only when authorized by an optometrist or ophthalmologist, the prescription therefor contains all necessary data, and the prescription has not expired. This section shall not be construed as authorizing any optician or other person selling eyeglasses or contact lenses on prescription as authorized above to use any instrumentation or determine any data by performing any type of examination or corneal evaluation necessary for the fitting of contact lenses or to use any drugs in relation thereto.

(c) Nothing in this chapter shall apply in any way to any licensed physician, nor to any physician assistant or ophthalmic assistant program conducted under any accredited state university program, nor to any physician's assistant as defined in Section 34-24-292. Nothing in this chapter shall be construed as preventing an ophthalmologist from using assistants normally used in his or her practice under his or her direct personal supervision in the office in which the ophthalmologist normally actually practices his or her profession and nowhere else.
