Your eyeglasses or contact lens prescription may be valid longer than you think! Most prescriptions are good for a minimum of 1 year, some are good for 2 years.
Some states leave the maximum length open-ended. The prescribing doctor has the option to put an expiration date on your prescription. Even if your state allows
open-ended prescriptions, the doctor could put a time limit on it within state laws. Find out how to save on your contact lenses here with or without a current prescription.
