No, and no legitimate seller will sell you any.
Contact lenses are medical devices in the United States. Federal law requires a valid prescription for every pair, including colored lenses with no vision correction in them at all. Any website selling contacts without asking for prescription information is breaking that law.
Here is the good news, and it is the part most people get wrong: you probably do not need a new eye exam. You need your existing prescription, and it may still be valid. Check the expiration date printed on it before you assume anything.
Most people who search this are not trying to break the rules. They ran out of lenses, they think their prescription lapsed, and they want to know what their options are. So let’s go through what the law actually requires, how long your prescription really lasts, and what happens behind the scenes when you place an order.

Why a prescription is required at all
A contact lens sits directly on your cornea and blocks part of the oxygen your eye needs. Fit matters enormously. Two people with identical vision can need completely different lenses, because the curve and diameter of their eyes differ. A lens that fits badly can scrape the surface of the eye, trap bacteria underneath, or starve the cornea of oxygen.
That is why the FDA classifies contact lenses as medical devices rather than merchandise, and it applies to every kind. Colored lenses, Halloween lenses, and anime-style lenses with no corrective power are regulated exactly the same way as a lens correcting a strong prescription. The FDA is blunt about it: decorative lenses sold without a prescription at costume shops, beauty supply stores, or novelty websites are being sold illegally.
So when a retailer asks for your prescription details and your eye doctor’s name, that is not an upsell or a stalling tactic. It is the legal condition of the sale.
Can I order with an expired prescription?
No. Under the federal Contact Lens Rule, a seller may not fill a prescription the prescriber has confirmed is expired or otherwise invalid. That holds in every state and at every retailer, whether you order online, by phone, or walk into a store.
There is no workaround, and you should be suspicious of any seller who offers one. What you can do is check whether it is genuinely expired, because a surprising number of people assume a one year limit when their prescription actually runs longer.
If it really has expired
Book an eye exam with your eye doctor. That visit gives you a current prescription and, more to the point, checks that your eyes have tolerated the lenses well since the last one. Bring the boxes your lenses came in so the doctor can see exactly what you have been wearing.
How long is a contact lens prescription good for?
Federal law sets a floor, not a fixed term. The FTC requires contact lens prescriptions to be valid for at least one year, unless your prescriber documents a medical reason for a shorter period. Your prescriber can choose to write it for longer, and some states require them to.
The 30 second version
Look at the prescription itself. The expiration date is printed on it. That date is the answer for you specifically, and it beats any general rule you will read online, including this one. If you cannot find your copy, your eye doctor’s office can tell you the date over the phone.

States that go beyond the federal one year
This is where most published lists go wrong, including some that look authoritative. They flatten every state into a single number, but state laws come in two different shapes, and the difference decides whether you actually have two years or not.
Some states set a longer default. Your prescription runs about two years unless your doctor had a health reason to shorten it.
| State | What the law says | Citation |
|---|---|---|
| Florida | Valid to be filled for 2 years from the date of the original prescription | Fla. Stat. 484.012(2) |
| Minnesota | Must expire 2 years after it is written, unless a different date is warranted by your ocular health | Minn. Stat. 145.712 |
| Washington | Expiration cannot be set under 2 years unless your ocular health warrants it, and lenses cannot be dispensed on a prescription over 2 years old | RCW 18.195.030, 18.195.040 |
Other states set a ceiling instead. The law caps how far out your doctor may date the prescription, but they can still write it for one year. So in these states, two years is the most you might have, not a guarantee. Read your own expiration date.
| State | What the law says | Citation |
|---|---|---|
| California | Not less than 1 year and not more than 2 years from issuance, so your date falls inside that window | Cal. Bus. & Prof. Code 2541.2 |
| Maryland | Not more than 24 months from the time you were first examined | Md. Health Occ. 11-404.4 and 14-507 |
| New Mexico | Not more than 24 months from the time you were first examined | NMSA 61-2-10.5 |
| New Jersey | Valid provided it is not more than 2 years old | N.J.A.C. 13:35-5.1 |
| Iowa | Expiration not to exceed 18 months | Iowa Admin. Code r. 645-182.3 |
| Louisiana | Expiration not to exceed 18 months | La. R.S. 40:1299.97 |
Every other state. The federal floor applies, so your prescription is good for at least one year unless your prescriber documented a medical reason to make it shorter. Your prescriber may still choose to write it longer, and a handful of states not listed above have their own provisions we could not confirm in the text of the law. If your state is missing here, do not assume one year is your limit. Read the date on your prescription, and your state optometry board can confirm the current rule.
Every figure above was read in the statute or regulation itself, and each one is linked in the sources. We have deliberately not filled in states we could not verify, because the published lists disagree with one another and a confident wrong answer is worse than an honest gap.
What actually happens when you place an order
This part is rarely explained, and understanding it removes most of the anxiety around ordering online.
You have two ways to prove you have a prescription. You can send a copy of it, which is the fastest route. Or you can enter your prescription details and your eye doctor’s contact information, and the seller verifies with the doctor directly. That second path is called verification, and it runs on a specific federal timetable.
1 You place the order with your prescription details and your eye doctor’s name and phone number.
2 The seller contacts your prescriber by phone, fax, or email with the exact details you supplied.
3 The clock starts. Your prescriber has eight business hours to respond. Business hours mean 9am to 5pm, Monday through Friday, excluding federal holidays, in your prescriber’s time zone. So a request sent Friday afternoon may not run out until Tuesday.
4 If they confirm, your order ships. If they say nothing at all within those eight hours, the prescription is considered verified automatically and the order can ship. That is written into the federal rule, and it exists so a slow office cannot keep you from buying elsewhere.
5 If they say it is expired or wrong, the order stops. The seller is not allowed to ship it. You will be contacted, and the fix is a current prescription.
Sending a copy of your prescription up front skips the waiting entirely, which is why it is worth digging the paperwork out of the drawer. You can send yours to us before, during, or after checkout.
Your rights, which are stronger than most people realize
The FTC gives you specific protections that a lot of patients never hear about.
✓ You get a copy automatically. Your prescriber must hand you your contact lens prescription at the end of your fitting, even if you never ask for it.
✓ They cannot charge you for it. No extra fee for the piece of paper.
✓ They cannot require you to buy from them. You are free to take your prescription anywhere.
✓ You can report a prescriber who refuses. The FTC takes complaints at ReportFraud.ftc.gov.
One detail worth knowing: a glasses prescription is not a contact lens prescription. A contact lens prescription includes a base curve and diameter, and it names a specific brand, because those numbers are measured against your eye and that particular lens. If someone hands you a glasses prescription and tells you it will do, it will not.
The bottom line
You cannot buy contact lenses without a prescription in the United States, and that rule protects something you cannot replace. What you can do is find out whether the prescription you already have is still valid, because the answer is yes more often than people expect, especially in states that run to two years.
Look at the date printed on your prescription. If it is current, you are ready to order today. If it has passed, book an exam and you will be set for another year or two.
Frequently asked questions
Can you buy contact lenses without a prescription?
No. Contact lenses are regulated as medical devices in the United States, and federal law requires a valid prescription for every purchase. This includes colored and costume lenses with no vision correction in them. Any seller who does not ask for prescription information is breaking the law.
Can I order contacts with an expired prescription?
No. Under the federal Contact Lens Rule, a seller cannot fill a prescription that the prescriber confirms is expired. Before assuming yours has lapsed, check the expiration date printed on it, since some states require prescriptions to run two years rather than one.
How long is a contact lens prescription good for?
At least one year under federal law, unless your prescriber documented a medical reason for a shorter period. Some states go further, and they do it in two different ways. Florida, Minnesota and Washington set a longer default of about two years. California, Maryland, New Mexico, New Jersey, Iowa and Louisiana instead cap how far out a prescriber may date it, which means you might have one year or you might have more. The date printed on your prescription is the one that governs.
Can I use my glasses prescription to buy contacts?
No. A contact lens prescription contains measurements a glasses prescription does not, including base curve, diameter, and a specific brand, because a contact lens is fitted to the surface of your eye. The two are separate documents and require separate fittings.
Does my eye doctor have to give me my prescription?
Yes. The FTC requires prescribers to give you a copy at the end of your contact lens fitting, automatically and at no extra charge, whether or not you ask. They also cannot require you to buy lenses from them. If a prescriber refuses, you can report it to the FTC at ReportFraud.ftc.gov.
What happens if my eye doctor never responds to a verification request?
The prescription is verified automatically and the order can ship. Federal rules give the prescriber eight business hours to reply, counted from 9am to 5pm on weekdays in the prescriber’s time zone. Silence past that window counts as approval, so a slow office cannot prevent you from buying elsewhere.
Do colored or Halloween contacts need a prescription?
Yes, even with no vision correction in them. The FDA regulates decorative lenses exactly like corrective ones, because they carry the same fit and infection risks. Lenses sold at costume shops, beauty supply stores, or novelty sites without a prescription are being sold illegally. The FDA lists corneal scratches, allergic reactions, decreased vision, infection, and blindness among the risks of lenses obtained that way.
I lost my prescription. What now?
Call the office that performed your fitting and ask them to send a copy. They are required to keep records and they can confirm the expiration date over the phone. If your prescription is still valid, that copy is all you need to order.

A note on the above: this article is general education. It is not legal advice or medical advice. Federal and state rules change, and only a licensed eye doctor can determine what is right for your eyes. Confirm current requirements with your state optometry board and your prescriber. If you have eye pain, redness, light sensitivity, or a sudden change in vision, remove your lenses and contact your eye doctor.
