If you e-mail or upload your prescription to us, we have all the details we need to be able to verify it's validity with your doctor as their contact info should be featured on the scan. If you decide to provide us only with your doctor's contact details, we will contact them and have them check whether the items you added while shopping with us match your prescription. Your eye care provider has 8 working hours to get back to us which does slow the process down a little but provides you with that extra level of protection. According to the Federal Law, your eye care provider is required to give you a copy of your prescription, so remember to always ask for it before the end of your appointment.
