Before you take prescription eyeglasses, you have to get a prescription. First, you need to go to an Optometrist (someone you examines your eyes). If they tell you that you need glasses they will write a prescription for you on a piece of paper. After you get the prescription, you need to go to an Optician (someone who sells prescription glasses). Once you go to one, find a pair of glasses that you like, and give them your prescription so that they can order the specific glasses you want with the prescription in it. Depending on the place it may take from 1 hour to 1 week to receive the order. They usually call you when your glasses are ready.
