The diamond-shaped face is also of the straight line type, so it is best to have straight edges. For men, don't have too many curves. You can directly choose the cheapest eyeglasses that look more sharp. For women, they can choose something softer to look gentler.

For a triangular face, the forehead is wider and the chin is narrower, giving it a fuller appearance above and a thinner appearance below. So the main thing is to balance the relationship between top and bottom. Therefore, we can choose which eyeglass frames are heavier at the bottom, which can visually increase the width of the chin.

Unlike diamond-shaped faces, the upper edge line no longer needs to protrude. Because the forehead is already quite broad. The specific shape can be chosen without obvious crossbeams.

Triangle faces are also of the straight line type, so the edge lines also need to be straight. For men, straight lines around the edges look more neat. For women, they can choose something softer to look gentler. Similarly, the crossbeam does not need to be too obvious.

For a round face, not making the face look rounder can make it appear more mature, so the main goal is to avoid overly rounded men's eyeglass frames. Choosing an eyeglass frame with a straight upper edge line can break the roundness.

For men, the shape with a dot square looks more sharp. For women, they can choose a browline framed circular or heart-shaped shape.

For oval-shaped faces, it is important to choose slightly wider shapes to make the face look shorter and more attractive. Because it is a curved face, the shape of the glasses needs to have curves to be harmonious.
