The best frame is the one that suits you.
You can choose the full-frame, because the edge of the lens is relatively thick, which can block the thickness of the edge, so it is suitable for high myopia to choose. They can choose a smaller frame. The size of the eyeglass frame should match the pupil distance so that the edge thickness of the lens is thinner and they are more comfortable to wear. The size of the frame should be proportional to the size of the face. The upper edge of the frame should not be higher than the eyebrow and the eyebrow should not be visible in the lenses. The shape of the frame should match the face shape and skin tone to meet aesthetic requirements. Everyone's face size is different, so the smaller the frame is, the better, based on what fits you and what you like.
