Sunglass Guide

Sunglasses are an essential part of your summer wardrobe. They help protect your eyes on the days when the sun is at its brightest, but they are also an important part of your outfit. The sunglasses you choose have a big impact on your face and the features they offer vary from model to model. In Byflou's sunglasses guide you will be guided to choose the right sunglasses for you and your face shape, as well as tips for finding the best protective sunglasses.

Which sunglasses suit your face?


When buying sunglasses, it's all about finding the shape that suits your face best. Some people swear by the timeless look and invest in one pair that will last year after year. Others see sunglasses as an accessory that can be changed according to mood, outfit or season. Whether you're going for the safe choice or experimenting with trends, it's ultimately about finding the right balance between style and fit.

The round face

The round face is characterized by a lack of facial contours, indistinct cheekbones and an overall short face. With square glasses and sharp edges, you can balance the soft lines of your face. You may want to choose a thick frame in a darker color or with a pattern to accentuate the edge of the sunglasses. Avoid completely round sunglasses or oval styles, as well as transparent frames.

The heart-shaped face

If you have a heart-shaped face, you will typically have a narrow jawline with a broader forehead and prominent cheekbones. A model with weight at the bottom of the frame will be ideal here. Look for models that start at the cheekbones, which will make your jawline appear wider - classic aviators are a good choice here. Avoid sunglasses with weight or embellishment at the top of the frame as this will make your forehead appear larger.

The oval face

If you have an oval face shape, you're in luck when it comes to choosing sunglasses. This face shape is typically longer, with a narrow jawline and a narrow forehead. You may want to go for cat-eye style glasses to lift your cheekbones. However, always choose glasses that fit the width of your face to emphasize the narrow qualities of your face.

The square face

The square face is typically characterized by a wide jawline, a broad forehead and prominent facial features. That's why it's important to balance these strong lines with soft round shapes in your sunglasses. Round and oval sunglasses will be ideal for this face shape, and a thin or light frame will give a soft look to your face. If you have the square face shape, you should avoid sunglasses with sharp edges and a square shape.

Polaroid, UV and tinted lenses - What are good sunglasses?


UV protection

The most important function of sunglasses is of course to protect your eyes from the sun's harmful UV rays. UV rays not only damage your eyes, but also the skin around your eyes. The sun's rays are the typical cause of wrinkles forming around and under the eyes, which is also a relevant thing to consider when choosing sunglasses.

Unfortunately, not all sunglasses are equally good at shielding your eyes from the harmful UV rays. That's why it's important to look at the sunglasses' UV label before you buy your next pair of sunglasses. All sunglasses at Byflou.com are labeled with UV400, which is one of the highest qualities in sun protection. UV400 blocks all forms of UV radiation and is therefore the best choice if you want to protect both your eyes and the surrounding skin.

Lens type and color

Sunglass lenses are now available in an endless palette of colors, and to a large extent it's a matter of taste what color sunglass lenses you choose. It could be a color that matches your skin tone, is especially popular for the season or matches your wardrobe. But sunglass lenses often have a unique function too, so why not choose a pair that is stylish, flattering and practical.

Polarized lenses are a classic choice for the active sunglass wearer. The lenses have a reflective function that bounces light back and ensures minimal glare in your eyes. This makes them practical when you're on the water or doing other activities in direct sunlight.

A green or yellow sunglasses lens is good if you want to relieve eye strain. They highlight contrasts in your surroundings and maintain a neutral color balance, making them great to keep in your car when you're on the road.

A grey lens creates a neutral tone to the colors around you, which means they don't give off the warm summer glow that dark or brown lenses do.

A lens in a pink or light red tone is especially good in shaded environments. Although it seems contradictory to wear sunglasses when you're not in direct sunlight, they're great for relieving eye strain when you're driving or walking around town.

The classic brown sunglass lenses are the ones you see in most models. They create that familiar warm glow to the surroundings and provide a certain anonymity to the eyes that lighter colored sunglass lenses do not. Brown sunglass lenses are also a great alternative to black colors as they give a softer look to your face, where black lenses can give a very harsh contrast.

The season's most popular sunglasses styles.


Trends in sunglasses change, just like everything else in the fashion world. Some choose to invest in one pair of stylish sunglasses, with a classic design that can be worn for many years. Others prefer to have sunglasses for every outfit - preferably in many different styles and colors to match the season.

If you recognize yourself in the first statement, you should definitely choose a stylish classic. A black or transparent frame that matches any wardrobe is ideal. You should go for a frame with a classic shape that naturally fits your face, so you always know you look good when you put on your sunglasses. At the same time, there are some special styles to look out for if you want to keep up with the latest trends.

The 70s sunglasses

The nostalgic 70s glasses are back in fashion, both with and without sun protection. An oversized frame with angular shapes, voluminous golden details and graduated lenses in brown shades are a staple on runways and social media. The ultra retro design can be found in several aspects of fashion and can even be a good investment as this style is regularly trending.

The modern style

Sunglasses with a sporty outdoor design have also found their way to the big fashion platforms. The sports-inspired model comes in many forms, with both authentic activity sunglasses with polarized lenses and the more stylish versions gaining popularity. They add a bold and contrasting look to your everyday outfits, which is super fashionable this season.

The 00s sunglasses

The last sunglasses model you should be looking for is the very narrow one. Here again, you can find many different options from popular brands. The narrow model, usually available in an oval or rectangular design, is often seen with wide and colorful frames that in many ways resemble a more stylish version of the sporty glasses. Also, the popular 00s model, with free-standing colored lenses and a narrow metal frame, has been revived by several major fashion houses.
