§7604 Expiration of contact lens prescriptions

Summary

Contact lens prescriptions expire based on state rules or the prescriber's medical judgment. If a State sets an expiration date that is one year or more after the day the patient gets the prescription, that date applies. If the State sets no date or a shorter date, the prescription must last at least one year unless the prescriber chooses a different date for medical reasons. If the prescriber makes the expiration less than one year, they must write the medical reasons in the patient's record. The expiration cannot be shorter than the time the prescriber says is medically needed for a reexamination. "Issue date" means the day the patient receives a copy of the prescription.
