The certificate does not cover the cost of an appointment with an opthalmologist or optometrist -- which you need to have to get a contact lens prescription.
The site explains the process of getting a contact lens prescription, including how much time you should expect to spend at the doctor's office, how long you can expect to wait for your lenses and more.
You take the certificate to your doctor to get the free pair of lenses.
