You will register your prescription from your local optician in your account on PantoGlasses, together with address and contact information. When/if you want to revert to us for additional products or others, we will have your information safely registered. Your account is like having a analog or digital file with your optician. We will never share this information with anyone. If you decide to buy PantoGlasses without saving your information, this is of course also possible.
