Normally, we choose the model that we think is the most beautiful, or that suits us. But know that there are perfect glasses for every face type. Check out this selection of tips on how to choose the sunglasses that match your face shape:
First, find out your face type
To find out the shape of your face, do the following: with lipstick, stand in front of a mirror. Try not to move and trace the outline of your face on the surface of the mirror, starting with your chin and ending with your hairline. Take a step back and check out your face shape.
Round face
Your goal is to visually lengthen your face, so choose glasses with angles, they narrow the face. To balance your facial proportions, choose glasses where the width is greater than the height.
Oval face
In this case, the main objective is not to disturb the harmonious proportions of your face. Therefore, you should avoid glasses with too many angles. Preferably, the glasses should be as wide as your face, or a little wider. Make sure the top of the lens comes up to your eyebrows.
Square face
Very angled features can “overload” the contours of your face. On the other hand, rounded glasses will help to balance and smooth out facial proportions.
Rectangular face
The goal is for your face to look visually wider. Look for big, bold-looking glasses. Also, make sure they have clear lenses and slim frames that match your skin tone.
Heart-shaped face
Your goal is to balance the upper part of the face by making the lower part look bigger. Look for glasses that don’t increase the volume of the upper part of the face. We recommend that you choose glasses where the width is equal to the width of your face. Opt for a teardrop-shaped design. “Aviators” would be ideal.
Triangular face
Your main goal should be to visually enlarge the top half of your face while making the bottom half look smaller. Choose sunglasses with a large frame and a wide top. The bottom should not have square or sharp edges.
