Eyeglass frames that suit the shape of your face will enhance your looks. There are basically three things that you need to consider when selecting an eyeglass frame.
1. It should highlight your best feature (For example, if you have blue eyes, choose blue frames.)
2. The shape of the frame should contrast with the shape of your face.
3. The size of the frame should be proportionate to the size of your face.
There are basically seven face shapes: oval, round, diamond, oblong, base-up triangle, base-down triangle, and square.
Here are some guidelines for choosing eyeglass frames.
Round
A round face has no angles. The curved lines along the length and width of the face are in the same proportion. An angular narrow eyeglass frame will make the round face look thinner and longer. The frames should have a rectangular shape. That means they should be wider than they are deep.
Oval
If you have an oval face, you are lucky because you can choose a wide variety of frames. An oval face has balanced proportions and to keep its natural balance, you should wear frames which are as wide as the broadest part of your face. Walnut-shaped frames which are neither too narrow nor too deep will look best on an oval face.
Oblong
Oblong faces are longer than they are wide. You can make them appear shorter by wearing a frame that has more depth than width. Aviator frames are ideal for oblong faces.
Base-Down Triangle
If you have wide chin and cheek areas and a narrow forehead, you should add width to the narrow upper part of your face. Use frames accented with colors.
Base-Up Triangle
If you have a broad forehead and wide cheekbones that narrow to a small chin, you will need frames that will reduce the width of the top of the face. Rimless glasses look best on these faces. Frames which are wider at the bottom are also great choices.
Diamond
Diamond shaped faces are rare. They are narrow at the jawline and eye line and have broad and high cheekbones. Choose frames that will soften the cheekbones and highlight the eyes. They should have distinctive brow lines. Tiny rimless frames will also look good on a diamond shaped face.
Square
If you have a strong and square jawline and a broad forehead, you have a square face. The length and width of a square face are in the same proportions. Narrow oval frames are suitable for square faces. Frames which have more width than depth are also good choices.
