16 CFR Part 315
The Contact Lens Rule contains two key requirements. The first requirement is that contact lens prescribers (i.e., optometrists and ophthalmologists) must provide patients with a copy of their contact lens prescriptions at the completion of a contact lens fitting. The second requirement is that a contact lens seller cannot provide contact lenses to its customer unless the seller either obtains a copy of the prescription or verifies the prescription information with the prescriber through procedures set forth in the Rule. The purpose of these requirements is to enhance consumer choice and competition among contact lens sellers, thereby benefitting consumers.
