In most states, your contact lens prescription is valid for exactly one year from the date of your eye exam. Federal law sets this as the minimum under the Fairness to Contact Lens Consumers Act. Florida is one of the few states that allows a 2-year prescription, but your doctor still controls the expiration date they write. Once it expires, you cannot legally order more contacts until you get a new exam.
Done in seconds. No sign-up required.
Federal law (FCLCA) sets the floor at 1 year. States can extend that minimum but not shorten it. Here are examples of how selected states handle expiration:
| State | Validity period | Notes |
|---|---|---|
| California | 1 year | Matches federal minimum; no state extension |
| Texas | 1 year | Matches federal minimum; no state extension |
| New York | 1 year | Matches federal minimum; no state extension |
| Florida | Up to 2 years | Doctor may still set 1-year expiration at their discretion |
| Illinois | 1 year | Matches federal minimum; no state extension |
| Pennsylvania | 1 year | Matches federal minimum; no state extension |
| All other states | 1 year (minimum) | Check your state board of optometry for any extensions |
When in doubt, check the expiration date printed on your prescription. That date controls, regardless of what your state allows.
The moment your prescription expires, any order you place for contacts will be rejected. Online retailers, big-box stores, and your local optometrist's office are all required by federal law to verify a valid prescription before selling you lenses. There is no grace period.
This creates a compounding cost problem. If you let the prescription lapse and run out of lenses, you are looking at an unplanned exam appointment, potentially an additional fitting fee if your prescription or lens brand has changed, a wait for the new prescription to clear verification, and possible shipping delays if you order online. What could have been one well-timed appointment becomes an urgent scramble.
There is also a health angle. Wearing lenses past their replacement schedule or continuing with a prescription that may have changed increases the risk of discomfort and eye health issues. The annual exam is not just a bureaucratic hurdle, it is a check that your prescription still fits.
The most direct way to avoid this is a contact lens renewal reminder set 4 to 6 weeks before your prescription expires. That window gives you time to schedule, attend the exam, and have the new prescription ready before your supply runs short.
Check your prescription paperwork or your online account with your eye care provider. The expiration date is printed on the prescription itself.
That lead time lets you book the appointment without urgency. Eye doctors, especially in spring and fall, fill up quickly.
A routine contact lens exam usually takes under an hour. Your new prescription is valid immediately after your fitting is confirmed.
With the new prescription in hand, place your order while you still have a few weeks of lenses left. Avoid same-day pressure.
Federal law requires a minimum 1-year validity period for all contact lens prescriptions. Most states follow this exactly, meaning your prescription is valid for one year from the exam date. A handful of states, including Florida, allow 2-year validity, but the issuing doctor may still choose to set a 1-year expiration.
No. The Fairness to Contact Lens Consumers Act (FCLCA) requires sellers to verify a valid prescription before filling any order. An expired prescription cannot be used to purchase contacts online or in-store, regardless of how recently it expired.
You will need to schedule a new eye exam before you can order more lenses. If you run out of lenses before the appointment, you may have to wear glasses in the meantime. Some eye doctors will grant a short extension in an emergency, but this is at their discretion and not guaranteed.
No. A glasses prescription and a contact lens prescription are different documents. Contact lens prescriptions include additional measurements specific to lens fit, such as base curve and diameter. You cannot use a glasses prescription to order contacts.
Under the FCLCA, eye doctors are required to give you a copy of your contact lens prescription at the end of your fitting exam, at no extra charge, whether you ask for it or not. You are then free to use it at any retailer.
Schedule your exam 4 to 6 weeks before your current prescription expires. This gives you enough time to get the appointment, complete a contact lens fitting if needed, and have the new prescription verified before your supply runs low.
