Do you have any idea about how to choose the right eyeglasses shape to complement my face? So many different types of eyeglasses frames at the online prescription glasses stores, it is difficult to choose the right one. Could you please give me suggestions? Thanks!

I think you should choose the shape of eyeglasses frames contrast with the shape of your face.

As we know that the stronger prescription we have, the thicker lenses edge there will be. High index and aspheric lenses are thinner than ordinary lenses.
They can give you more attractive appearance.
