This represents the horizontal width of the opening on one eye. This number usually ranges from 42-58mm. The larger the value, the larger the frame. The second number, represented by BB, measures the distance between the right and left lenses, which usually ranges from 16-24 mm. The CCC value is the length of the handles, usually between 130-150mm. The bigger your head, the bigger this number should be so your glasses can fit comfortably on your face.
