Two options isn't much of a choice at all. The more options you have, the more likely you are to find the perfect frame. That is why we make all glasses in various sizes and colors.
These glasses are available in the size:

38 - 19 / Small
41 - 20 / Medium
43 - 21 / Large

Glasses without optical lenses:
We only supply the frame. For optical lenses go to your local optician.
