mm (Small) to 62 mm (Large or Oversized).
As for the width of the frame, it is measured from the outside of the frame and is usually between 120 and
150 mm. The frame width is not specified on the temple arm and to understand which frame size is right for
you, use the parameters of the previous frame or by measuring your face yourself. The width of the face is
measured from temple to temple at eye level. It should be remembered that the temple arm also has a width,
and therefore it is necessary to measure with a small margin.
