How Long Is an Eyeglass Prescription Good for in Florida?

An eyeglass prescription is good for five years in Florida, measured from the date your eye doctor originally wrote it. Florida Statute 484.012 sets that window, and it’s one of the longest in the country. Your prescribing doctor can shorten it for medical reasons by marking the prescription non-duplicable, and contact lens prescriptions follow a shorter clock.¹

How the Five-Year Clock Runs

The statute is worded more narrowly than most people assume. It doesn’t say your prescription is “valid” for five years in the abstract. It governs how long a duplication of the original prescription can be used to order new eyeglasses. When an optician fills your original, you can request a copy on a form approved by the state board, and that duplicate remains usable for up to five years from the date the prescription was written.¹

So if your exam was on March 1, 2026, you can use that prescription (or a duplicate of it) to buy new glasses as late as February 2031. The clock starts the day the doctor signed it, not the day you had it duplicated or the day you first filled it.

When Your Doctor Can Shorten the Window

Your ophthalmologist or optometrist can write directly on the prescription that it may not be duplicated. Under the statute, this restriction is only permitted for medical reasons, not as a business practice to bring you back sooner.¹

Conditions that commonly prompt this kind of restriction include rapidly progressing myopia, unstable diabetic eye disease, keratoconus, and recent eye surgery where the prescription is expected to shift. If your prescription carries a no-duplication note, an optician can’t make you another pair off of it, and you’ll need a fresh exam even if the five years haven’t run.

Separately, Florida’s administrative code requires optometrists to perform a comprehensive exam before providing further care when the last one was more than two years ago.² That rule addresses what optometrists must do at a visit; it doesn’t cut short the validity of the prescription you already hold. But it reflects the interval professionals treat as reasonable.

Duplicating Lenses Without a Prescription at All

Florida law also permits a licensed optician to duplicate your existing lenses based on their optical power alone, with no prescription required.¹ Walk in with your current glasses, and the optician can measure the lenses and produce a matching pair.

That means an expired prescription, or lost paperwork, doesn’t always leave you stuck. The optician isn’t examining your eyes or issuing anything new; they’re reproducing what you already own. It won’t help if your vision has shifted, but it’s a real option for a backup pair or broken frames.

Contact Lenses Are on a Different Timeline

Contact lens prescriptions in Florida are valid for two years from the original prescription date, well under half the eyeglass window.¹

Federal law adds a floor. The Fairness to Contact Lens Consumers Act requires that a contact lens prescription be valid for at least one year, unless a shorter period is medically justified and documented. Florida’s two-year period exceeds that floor, so the state rule controls for Florida residents.³

An eyeglass prescription can’t be used to buy contacts. Contact lens prescriptions include measurements, such as base curve and lens diameter, that don’t appear on an eyeglass prescription.

Getting a Copy of Your Prescription

The FTC’s Eyeglass Rule requires your eye doctor to give you a copy of your prescription immediately after a refractive exam, before offering to sell you glasses. You don’t have to ask, and no extra fee can be attached to it. The copy may be on paper or digital.⁴

Even asking whether you want the prescription, rather than handing it over automatically, doesn’t meet the rule.⁵ Having the prescription in hand is what lets you use those five years anywhere you want to buy glasses, in person or online.

What to Do When the Five Years Are Up

Once the window closes, most optical retailers won’t fill new lenses off that prescription or any duplicate of it. The one Florida-specific fallback is lens duplication by power, described above.¹

To restart the clock, book a comprehensive eye exam with a licensed optometrist or ophthalmologist. The visit typically covers an eye chart, a refraction test to set your lens power, and an assessment of overall eye health. A new prescription resets the five-year period from its own date.
