The newly-made large-rimmed glasses have aspherical lenses, and their faces are deformed when they look in the mirror. The left face is bigger than the right face, and the left face is bigger than the right face. It's normal to take selfies with your mobile phone. Myopic lenses are concave lenses, and the thin edge areas in the central area of the lenses are thicker. The greater the curvature of the outer surface of the lens, the greater the curvature of the inner surface, the greater the thickness of the edge and the smaller the actual effective visual field. Therefore, the higher the magnification of the lens, the smaller the curvature of the outer surface. So it has something to do with the big box you choose. If the big frame is really deformed, change it to a small frame.
