Yes — you need a valid prescription to buy colored contact lenses in the United States, even if your vision is perfect and the lenses are zero-power (plano). This rule applies to every pair of contacts we sell, cosmetic or corrective. Here is why the prescription requirement exists, what your prescription actually means, and how ordering from us works.
In this guide:
- Why every contact lens — even plano — requires a prescription
- What SPH, BC, and DIA mean on your prescription
- How our checkout and verification process works
The Short Answer
Yes. U.S. regulations treat all contact lenses as medical devices and require a valid prescription — including zero-power (plano) cosmetic lenses. We cannot legally ship colored contacts without a prescription on file, and we do not try to work around that. The good news? Getting your prescription is quick, and our checkout is designed to make the whole process painless: you pick your power (or 0.00), place the order, and we verify your prescription before shipping.
Why Every Contact Lens Needs a Prescription
Contact lenses sit directly on your cornea, so they are regulated as medical devices rather than beauty products. A lens that does not fit well — the wrong base curve, diameter, or material — can scratch the eye, reduce oxygen flow to the cornea, and increase the risk of infection. Those risks apply to colored lenses exactly the same way they apply to clear corrective lenses.
This is why a plano lens still needs a prescription. A zero-power lens may not correct vision, but it still has to fit your eye correctly, and only an eye care professional can measure your eye and confirm the right fit. The word “decorative” does not change the medical reality.
If you have astigmatism, the rules matter even more — our guide to wearing colored contacts with astigmatism walks through your options in detail.
Prescription vs. Plano
“Plano” is the optical term for zero power, written as 0.00. Plano colored contacts are purely cosmetic — they change your eye color but do not affect your vision. Prescription colored contacts do both: they change your eye color and correct nearsightedness (−) or farsightedness (+) at the same time.
Both types legally require a prescription, but they serve different purposes. If you are deciding between them, our full breakdown of prescription vs. non-prescription colored contacts will help you choose.
What’s In a Contact Lens Prescription
A contact lens prescription contains more than just a power number. Here is what each part means:
| Abbreviation | What it means | Example |
|---|---|---|
| SPH | Sphere — the lens power. A minus (−) corrects nearsightedness, a plus (+) corrects farsightedness, and 0.00 means plano. | −2.50 |
| BC | Base curve — the curvature of the lens, matched to the curve of your cornea. | 8.6 mm |
| DIA | Diameter — the width of the lens, which determines how it sits on your eye. | 14.2 mm |
| CYL & Axis | Cylinder and axis — only appear if you have astigmatism, and they are used for toric lenses. | −0.75 / 180° |
If your prescription includes CYL and axis, you have astigmatism — read our toric colored contacts guide before you order so you pick the right type of lens.
How to Get Your Prescription
Getting a contact lens prescription is straightforward:
- Book a contact lens exam. A regular glasses checkup is not enough — you need a contact lens fitting, where the optometrist measures your cornea and checks how lenses sit on your eye.
- Ask for your prescription. By law, you are entitled to a copy of your contact lens prescription — you can take it to any seller.
- Check the expiration date. Contact lens prescriptions typically expire after one to two years, depending on your state.
A contact lens exam usually takes 20 to 30 minutes. If you only want cosmetic lenses, tell your doctor — they can write a plano prescription after confirming the lenses fit properly.
How Our Checkout Works
Our checkout is built so you never have to guess what to enter:
- Choose your power. Select 0.00 if you want plano, or enter your SPH power (for example, −2.50) if you want vision correction.
- Place your order. We collect your prescription details along with your lens color and size.
- Verify after ordering. We check your prescription through our prescription verification page before we ship.
No valid prescription, no shipment — it is that simple. If you are unsure what to enter, our customer service team will guide you after you place your order.
