Under federal law your prescription is good for 1-2 years, depending on the state in which your eye care provider is located. Most importantly, this one-year time period is from the date your eye doctor issues your prescription—not from the date of your eye exam.    We're advocates of proper eye health and encourage our customers to receive regular eye care. If you have provided us a copy of your prescription, we'll notify you when it's expiring. If it has already expired, we’ll call to remind you to visit your eye doctor for an eye exam and to receive an updated or new contact lens prescription.
