First, use a virtual try-on-feature to determine which frame shape is best for you. Then, compare the size of the glasses you are wearing today with the size of the frames on our website. This should give you a good feeling about how you look in your glasses. Usually, you will find a series of numbers inside the framework, such as 50-18-140. These numbers represent the width of the lens, the width of the bridge, and the arm length of the temple.
