Thank you for your question. You will actually be using your prescription when ordering your contacts. In fact all contact lens retailers must comply with the “Fairness to Contact Lens Consumers Act” which states the following:

1.) Any time an Eye Care Provider (ECP) conducts a contact lens fitting, that they must provide the patient with a paper copy of their prescription (whether or not the patient requests it). This enables the patient to take their prescription and purchase their Contact Lenses from a variety of sources.

2.) Contact lens sellers must verify that American patients have had a contact lens fitting and that the prescription is not expired.

This is a good thing because it ensures you get the right contact lenses.

And of course always talk to your eye doctor if you are ever in question.
