California Code
CHAPTER 5.4 - Prescription Lenses and Ophthalmic and Optometric Assistants
Section 2541.1.

2541.1. (a) A spectacle lens prescription shall include all of the following:

(1) The dioptric power of the lens. When the prescription needed by the patient has not changed since the previous examination, the prescriber may write on the prescription form “copy lenses currently worn” instead.

(2) The expiration date of the prescription.

(3) The date of the issuance of the prescription.

(4) The name, address, telephone number, prescriber’s license number, and signature of the prescribing optometrist or physician and surgeon.

(5) The name of the person to whom the prescription is issued.

(b) The expiration date of a spectacle lens prescription shall not be less than two years and shall not exceed four years from the date of issuance unless the patient’s history or current circumstances establish a reasonable probability of changes in the patient’s vision of sufficient magnitude to necessitate reexamination earlier than two years, or presence or probability of visual abnormalities related to ocular or systemic disease indicates, the need for reexamination of the patient earlier than two years. In no circumstances shall the expiration date be shorter than the period of time recommended by the prescriber for reexamination of the patient. Establishing an expiration date that is not consistent with this section shall be regarded as unprofessional conduct by the board that issued the prescriber’s certificate to practice.

(c) The prescriber of a spectacle lens shall orally inform the patient of the expiration date of a spectacle lens prescription at the time the prescription is issued. The expiration date of a prescription may be extended by the prescriber and transmitted by telephone, electronic mail, or any other means of communication. An oral prescription for a spectacle lens shall be reduced to writing and a copy of that writing shall be sent to the prescriber prior to the delivery of the lenses to the person to whom the prescription is issued.

(d) A prescriber of a spectacle lens shall abide by the rules pertaining to spectacle lens prescriptions and eye examinations adopted by the Federal Trade Commission found in Part 456 of Title 16 of the Code of Federal Regulations.

(e) An expired prescription may be filled if all of the following conditions exist:

(1) The patient’s spectacles are lost, broken, or damaged to a degree that renders them unusable.

(2) Upon dispensing a prescription pursuant to this subdivision, the person dispensing shall recommend that the patient return to the optometrist or physician and surgeon who issued the prescription for an eye examination and provide the prescriber with a written notification of the prescription that was filled.
