When it comes to sunglasses, asides from the fact that a perfect fit is more flattering in appearance, it’s also more comfortable and will best protect your eyes from the sun.

     As a general rule, when picking which shape or style of sunglasses to buy, you should choose frames that contrast the geometry of your face. Simply put, the shape of your sunglasses should be opposite to the shape of your face. This helps to create balance by either softening hard features or creating definition.

     Determining your face size and shape is important because it will help you find a better fitting, more functional pair of sunglasses. To find the best sunglasses for your face, you’ll need to:

  1. Measure your face shape: This is the biggest factor in determining which sunglasses will look good on you and which won’t. If you aren’t sure what face shape you have, try standing in front of a mirror and tracing the outline of your face with a lipstick or some other easily removable material. Once you’ve recognized your face shape, it’ll be much easier to find which frame shapes will bring a natural balance to your face.
  2. Match your face shape to a style of sunglasses: In this article, we’ll be looking at 5 main categories of face shapes and matching them to their perfect shape of sunglasses.
    • Square faces: A strong jawline and high cheekbones add up to a square face. Square faces have bold, angular features. Rounded and thinner frames that are slightly wider on the side will have a natural look on square faces. Frames such as aviators, butterfly frames, round frames and oval-shaped frames will look better on people with square faces than frames with angular shapes and sharp lines.
    • Round faces: People with round faces usually have fuller cheeks and rounded chins with very few angles. If you have a round face, you should opt for sunglasses that create as much definition as possible. Therefore, bold, angular shaped sunglasses with sharp lines are more advisable as they will make your cheeks appear slimmer, help to elongate your temples and lengthen your face. Wayfarers, square frames, Clubmasters, shield-shaped frames and rectangular frames are examples of frames that will work better for people with round face shape.
    • Rectangular faces: These are also called Oblong Faces. This face shape is long and narrow with few angles. To give this face shape a sense of balance, seek out glasses that add width to the long shape. Round or square frames works well with this face shape. Frames with sharp and bold lines will also give Oblong faces an edge. However, make sure to go for larger even slightly oversized sunglasses styles. Avoid getting sunglasses with small frames. Wayfarers, D-frames and Clubmasters are examples of frames that will look good on people with rectangular face shape.
    • Heart-shaped faces: Heart-shaped faces are widest at the brow, narrowing down through to the chin with high cheekbones. Due to the fact that a narrow chin is countered by a wider forehead in this face shape, it is important not to add extra weight to the top half of the face. People with this face shape look great in winged-out frames that cut slightly wider than their forehead, and has rounded bases to balance and complement their features. Examples of these type of frames are bottom-heavy frames, oval-shaped frames, light-colored or rimless frames, or round frames. Make sure to look specifically for sunglasses styles that have a deep base and subtle wingtips that are a bit wider than your forehead. Aviators and D-frame sunglasses are also great options for people with this face shape.
    • Oval-shaped faces: People with oval-shaped faces fit with most frame shapes. For an oval face, what you want to look out for is emphasizing the natural balance of your face and adding angles to its soft curves. With a narrower forehead and slightly narrow chin, oval is considered the most universal face shape, so you can have fun with the latest trends because most shapes work for you. You can make your choice of frames depending on the effect you’re looking for. That being said, the most suitable sunglasses frames for oval faces are square, rectangular or geometric shapes. Make sure to not get huge frames that block out your pretty symmetrical features; only choose sunglasses that cover your face from your eyebrows to your cheekbones. Also note that square sunglasses ensure more striking contours while round sunglasses create a more gentler impression.

     When making the decision of which style of sunglasses to buy, remember that it’s not just about fashion, it’s about protecting your eyes as well. So it’s important that certain UV-protection criteria are fulfilled. This means that, if possible, the frame should be as broad as your face at the temples, so as to prevent light getting in from the sides. The frame should also cover the entire eye area or even be a bit higher, so that light doesn’t shine in from above.
