The browline border crossbar frame refers to a horizontal beam in the middle of the eyebrow, presenting a double beam shape. The lines of this type of beam also have a significant impact on the shape of the glasses.

Square, but browline frame. We mainly use the frame lines on top, which are curved. So this is also a curved shape of glasses.

For square faces, making the face appear longer is the ultimate goal. Therefore, choosing browline frame glasses is the best option. That is to say, choose shapes with clear upper edge lines and transparent lower edge lines. A glasses frame that is too thick or too wide overall can make the face shorter and look very inappropriate.

Because a square face has a straight shape, the upper edge line should be straight. Square lenses can also be chosen for men. For women, it is best to appear softer and more feminine, so they can choose lenses with a softer lower edge line.

The rectangular face shape is also straight, so it is best for the edge lines to be straight. Men can choose rectangular glasses directly, while women can choose a rectangle with softer edges and corners.

For a diamond-shaped face, the forehead and chin are relatively narrow, so making them appear wider can achieve better visual effects. Therefore, we can choose eyeglass frames with wider upper edges to make the forehead look wider and with straight sides and heavier lower edges to make the lower half of the face thicker.

Diamond-shaped faces are also of the straight line type, so the edge lines should be straight. For men, don't have too many curves to look more neat. For women, they can choose softer options.
