A7: Since contact lenses are prescribed by brand, an easy way to know for sure if you have a contact lens prescription is to look for the actual name of your contact lenses on your prescription (an eyeglasses prescription will not have this information).

You should only wear contact lenses prescribed specifically for you under the close supervision of a qualified eye care professional.
