Sunglasses are extremely practical accessories. Not only do they protect your eyes from the sun’s damaging rays, but they also prevent wrinkles (because you don’t have to squint as much). But choosing your signature shades is no walk in the park – there’s size, shape and colour to contend with, not to mention the practicality of UV protection. Here’s a guide to picking the perfect pair.

Keep in mind that your face shape is as individual as you are and no two people are exactly alike. Faces are often a combination of shapes and can fall in between or change a bit as you age or even as you lose or gain weight.

Number 1 rule: Do the opposite

The general rule of thumb is to choose sunglasses that are the opposite shape to your face. So, if you have a square face, look for rounded curvy frames, and if you have a round face, look for square geometric frames. Heart-shaped faces are best suited to aviator or cat-eye styles, while oval faces can opt from any of the above. 

Rule no 2: Shop for the right size

An oversized frame on a petite face can look insectile, while a small frame on a large face is

equally unflattering. Try on different styles to make sure the lens, bridge and length of the frame’s arm suits you – you’ll be glad you did when you discover that you don’t need to constantly push the frames up the bridge of your nose. The larger and deeper the frame the shorter your face will look, so if you have a long face shape, choose a deeper frame.  If you have a shorter face (round or square) then choose a narrower frame. The scale of the frame should relate to your face, unless you are dramatic and want to express that part of your personality.

Rule no 3: Determine your face shape

Stand in front of the mirror and, on its surface, trace the outline of your face. If you have a round face shape, your objective when choosing the right pair of sunglasses is to give a lengthening effect to the face. Choose frames that are wider than your face or are slightly oversized, so that they will add balance to your soft features and balance your face to make it look longer or thinner. An oval face shape is the most versatile when choosing a flattering pair of sunglasses. Don't pick sunglasses that have prominent edges or that appear too big and wide. If you have a square face, choose large glasses with a frame width that is proportionate to the width of your face. In your case, it is recommended to avoid sunglasses with frames that are wider than your face.
