What is a Valid Eye Prescription?

If you have heard how important it is to have a valid eye prescription, you may wonder what that actually means. Here’s what a valid eye prescription means and how to ask for one from your eye doctor.

According to the FDA.gov website, a valid eye prescription means:

When you get an eye exam, the prescriber is required to give you a copy of your contact lens prescription when the fitting is complete, even if you don’t ask for it. You can use this prescription at another vendor or to order contact lenses on the Internet, over the phone, or by mail.”


“As defined by the Federal Trade Commission (FTC) in the contact lens rule, a prescription should contain sufficient information for a seller to completely and accurately fill the prescription. This includes the following items:

  • Patient’s name
  • Examination date
  • Date patient receives prescription after a contact lens fitting (issue date) and expiration date of prescription
  • Name, address, phone number and fax number of prescriber
  • Power of the prescribed contact lenses
  • Material and/or manufacturer of the prescribed contact lens
  • Base curve or appropriate designation of the prescribed contact lens
  • Diameter, when appropriate, of the prescribed contact lens
  • For a private label contact lens, the name of the manufacturer, trade name of the private label brand, and if applicable, trade name of equivalent brand name”
