Different face, choose different eyeglasses frames.
Round face, circular outline of the face formed by the curve, the same length and width, there is no point of view. If you want a little face looked thin and a little bit longer to try a square glasses frame, frame width is greater than the vertical width of the level. The best use of a transparent bridge frame.
Oval-shaped face, after wearing glasses in order to maintain this balance, the use of walnut-shaped ideal spectacle frames. Vertical width shold be not to much, nor too narrow. (more eyeglasses…)
