General regulatory information for clinic, lab and supply staff and for people comparing sources of lenses. It is not medical advice; an eye care professional decides what lenses a given person can wear.
Short answer
Yes. In the United States, contact lenses are medical devices that must be prescribed, and a seller may supply them only against a valid prescription or one the prescriber has verified. The FDA states that this includes decorative lenses with no vision correction. A prescription for glasses does not meet the requirement, because the federal definition of a contact lens prescription lists contact-lens-specific details.
Definition and scope
The Federal Trade Commission’s Contact Lens Rule (16 CFR Part 315) defines a contact lens as any contact lens for which state or federal law requires a prescription. The FDA’s position is that all contact lenses must be prescribed by a doctor, including decorative lenses, which it also calls colored, fashion, cosmetic, theatre or Halloween lenses. This page covers the United States only and covers the document itself; for the seller side of the same rule (verification, record keeping, trade accounts) see wholesale contact lenses.
How the prescription rules work in practice
The rule assigns separate duties to the prescriber, the seller and the patient.
| Who | What the rule requires | Source |
|---|---|---|
| Prescriber | At the end of the fitting, give the patient a copy of the prescription, whether or not the patient asks (16 CFR 315.3(a)(1)). | FTC rule text and guide |
| Prescriber | Provide a copy to a person designated by the patient on request within 40 business hours, and verify the prescription as directed. The prescriber may not make release or verification conditional on buying lenses, on extra payment, or on signing a waiver (315.3). | FTC rule text |
| Seller | Sell lenses only against a prescription presented by the patient or prescriber, or one verified by direct communication (315.5(a)). The FTC guide lists in person, fax, a scanned prescription attached to an email, or an uploaded copy or photograph. | FTC rule text and guide |
| Prescriber, on a verification request | A prescription is treated as verified if the prescriber does not respond within eight business hours of receiving the seller’s information (315.5(c)). | FTC rule text and guide |
| Patient | May take the prescription to another seller; the Fairness to Contact Lens Consumers Act gives the right to shop around. | FTC guide |
What a valid prescription shows
Under 16 CFR 315.2, a contact lens prescription is one issued under state and federal law that contains enough information for the complete and accurate filling of the order. The definition lists:
- the patient’s name, the date of examination, and the issue and expiration dates;
- the prescriber’s name, postal address, telephone number and fax number;
- the power, and the material or manufacturer (or both), of the prescribed lens;
- the base curve or appropriate designation, and the diameter when appropriate;
- for a private label lens, the manufacturer, the private label trade name and, if applicable, the equivalent brand name.
The FDA’s decorative-lens guidance gives a shorter consumer version: the prescription should include the brand name, the correct lens measurements and an expiration date.
On expiry, the rule sets a floor. A prescription expires on the date state law sets if that is at least one year after issue; otherwise it expires not less than one year after issue, unless the prescriber sets an earlier date based on medical judgment about the patient’s ocular health, in which case the reasons must be documented in the record for at least three years (315.6). Lens packaging dates are a separate matter, covered in contact lens expiration.
Where it matters for clinics and supply decisions
A source that supplies contact lenses can be checked against the same documents. Each item below traces to the FTC or FDA text above.
- It asks for a prescription or contacts the prescriber. A seller may not sell outside a presented or verified prescription. The FDA says a legitimate source requires a prescription.
- The lenses are FDA-cleared or approved. The FDA says a legitimate source sells FDA-cleared or approved contact lenses.
- The order matches the document. Power, manufacturer or brand, base curve and diameter on the order should match what the prescription lists; these are the items a verification request must carry (315.5(b)).
- Decorative products get the same treatment. The FDA names street vendors, beauty supply stores, flea markets, novelty stores, Halloween stores and unknown online distributors as sources that do not meet this standard.
- Clinic staff hold the patient’s copy and record the release. The prescriber is expected to note the name of any requester and the date and time a copy was provided (315.3(a)), and to request the patient’s acknowledgement of receipt of the prescription (315.3(a)(1)).

Common misunderstandings
“My glasses prescription is enough.”
The rule defines a contact lens prescription by contact-lens details such as base curve, diameter and lens material or manufacturer. A seller may sell only in accordance with a contact lens prescription for the patient.
“Decorative lenses are cosmetics.”
The FDA says decorative lenses are medical devices and must be prescribed like corrective lenses. It lists corneal abrasion, allergic reactions, decreased vision, infection and blindness among the risks of lenses obtained without an eye care professional’s input.
“The prescriber can hold my prescription until I buy lenses there.”
Not under the rule. The prescriber must give a copy at the end of the fitting and may not require the purchase of lenses as a condition of providing it.
“A site that says no prescription needed is just cheaper.”
The FDA’s warning is that obtaining lenses without a prescription is dangerous and that products from unknown online distributors may be contaminated or counterfeit. The agency also takes reports of unlawful internet sales and sellers that sell without a prescription.
The type of lens is a separate question from the prescription requirement; see hard vs soft contact lenses and contact lens materials.
FAQ
Do you need a prescription for colored or costume contact lenses?
Yes. The FDA states that all contact lenses must be prescribed by a doctor, including decorative lenses.
Can I use my glasses prescription to buy contact lenses?
No. A seller may sell contact lenses only against a contact lens prescription, whose required contents (base curve, diameter, lens power and material or manufacturer, among others) are set out in 16 CFR 315.2.
How long is a contact lens prescription valid?
At least one year from the issue date, or longer if state law sets a later date. A prescriber may set a shorter period only on the basis of medical judgment about the patient’s eye health, and must document the reasons (16 CFR 315.6).
Does my eye doctor have to give me a copy of my prescription?
Yes. At the end of the fitting the prescriber must give you a copy whether or not you ask, and may not make that conditional on buying lenses or signing a waiver.
Can I order lenses online?
The FDA says lenses are supplied by eye doctors, internet sellers and mail-order companies, provided the seller requires a prescription and sells FDA-cleared or approved lenses. The seller may take the prescription by upload or fax, or may verify it with your prescriber.
