You cannot get glasses with an expired prescription. State law sets how long an eyeglass prescription stays valid, and once that window closes, no retailer, optical shop, or online seller can legally fill it. Renewing is usually quick though, and depending on where you live and your health history, you may be able to do it from your phone in under an hour.
How Long an Eyeglass Prescription Lasts
There is no single national expiration date for eyeglass prescriptions. Unlike contact lens prescriptions, which must remain valid for at least one year under federal law, eyeglass expiration is left entirely to state regulation.1eCFR. 16 CFR 315.6 – Expiration of Contact Lens Prescriptions Most states set it at two years. Sixteen states use a one-year window. Louisiana lands at eighteen months, and four states have no regulated expiration at all, leaving the call to the prescriber.
Your own prescription may also carry a shorter expiration than your state’s default. If you have rapidly changing vision, diabetes, or early-stage glaucoma, your eye doctor can write the prescription to expire in as little as six months so you come back for a check before ordering new lenses.2Federal Trade Commission.

Renewing Online Without an Office Visit
If your vision has been stable, an online vision test can renew your prescription without an appointment. These services are available to residents of roughly 37 states. You take a series of vision tests using your phone or computer, answer screening questions about your health history, and a licensed eye doctor in your state reviews the results. The typical cost runs $15 to $50.
The eligibility rules are strict. Most services limit online renewals to adults between 18 and 55, and they screen out anyone with diabetes, a history of eye surgery, or other risk factors that require a hands-on exam. There is also a cap on how many times you can renew online before you have to come in for a full comprehensive exam.
Know what the online test does not do. It measures refractive error only. It cannot check the pressure inside your eye, examine your retina, or test peripheral vision, so it will not catch glaucoma, macular degeneration, or diabetic retinopathy. Treat it as a convenience tool between in-office exams, not a replacement for one.
Getting a New Prescription In Person
If you don’t qualify for online renewal, or you’d rather have a full workup, a comprehensive in-person exam at an independent optometrist typically costs $100 to $250 without insurance. Ophthalmologists, who are medical doctors, charge more, often $200 to $400. Add-ons like retinal imaging or pupil dilation can tack on another $30 to $80.
Vision insurance generally covers one routine exam per year with a small copay. If the exam identifies a medical issue such as glaucoma or cataracts, your regular health insurance may pick up the visit instead, subject to your deductible and coinsurance. The two rarely overlap: routine exams go through vision insurance, medically necessary exams through your health plan.
Both the exam and the eyeglasses themselves qualify as eligible expenses under a Health Savings Account or Flexible Spending Account. Paying with pre-tax dollars can effectively cut 20 to 30 percent off the cost depending on your bracket. If your FSA resets in January, using it early in the year while the balance is full is a practical move.
If Your Glasses Just Broke
Breaking your only pair while your prescription is expired puts you in a gray area. Most optical shops can physically read the values off your existing lenses with a device called a lensometer. Whether they can make new lenses from that reading without a current written prescription depends on your state. Some states allow opticians to duplicate lenses from an existing pair. Others require a valid written prescription for any new lenses, no exceptions.
Two things worth trying before booking anything:
- Call a local optician and ask directly whether they can duplicate your lenses in your state. Many can at least repair a broken frame or replace a lens in the existing frame without a new prescription, since that isn’t a new lens order.
- Ask your optometrist about same-day or next-day urgent appointments. Most offices reserve slots for exactly this situation. A quick exam is usually faster than working around replacement rules.
Reading Glasses Without a Prescription
If the only thing you need corrected is close-up vision for reading or small print, over-the-counter readers require no prescription. They’re sold at pharmacies, grocery stores, and online in standard magnifications from about +1.00 to +3.50, and they run from a few dollars to around $30.
The limit is real. Readers use the same magnification in both lenses and do not correct astigmatism or differences between your eyes. They won’t help with distance vision, driving, or computer work if you previously relied on prescription lenses for those tasks. For anything beyond casual reading, you’ll still need a current prescription.
Keep a Copy of the New Prescription
Once you renew, federal law requires your eye doctor to hand you a copy of the prescription immediately after the refractive exam, whether or not you ask for it, and before offering to sell you glasses.3eCFR. 16 CFR Part 456 – Ophthalmic Practice Rules (Eyeglass Rule) There is no extra fee beyond the exam. You can get it on paper or digitally through a patient portal or email if you agree to the digital format.
That copy is what lets you shop around. Once it’s in your hands, you can fill it at any big-box store, local optician, or online glasses retailer. The prescriber cannot require you to buy from them and cannot withhold the prescription to pressure a sale.4Federal Trade Commission. Complying with the Eyeglass Rule Snap a photo of it with your phone as soon as you get home. Next time a pair breaks or you want to reorder, you’ll have the numbers on you and won’t be stuck in the same spot.
