Let's start by defining what sunglasses are for.
Sunglasses are not just a fashion accessory – they protect the eyes from harsh sunlight.
We all know about UV radiation, which is extremely dangerous for the retina and can lead to partial or complete blindness. UV radiation is divided into two types: UVA and UVB. UVA rays are considered more harmful as they penetrate deeper into the layers of the skin (dermis) and the eye. They stimulate the production of free radicals, causing oxidative stress and potentially leading to indirect DNA damage.
The second type – UVB rays – are less dangerous for the eyes but can still cause visual damage when exposed intensely, leading to clouding, pain, and temporary blindness. These rays have a shorter wavelength than UVA rays.
To protect your eyes and the skin around them, it is crucial to wear sunglasses that provide appropriate ultraviolet protection. By the way, quality sunglasses are also “beneficial” for reducing deep forehead wrinkles that often form from squinting in strong sunlight.
And don’t be fooled – ultraviolet radiation doesn’t take a day off! Even in winter, it reflects off the snow and causes just as much harm to eye health. The biggest trap of UV radiation is cloudy weather, as clouds act like a “Trojan horse” allowing dangerous sun rays to harm unprotected, unsuspecting eyes.
The answer is simple: everyone! It doesn’t matter if you’re young, beautiful, and strong – when facing an enemy like the sun, you need serious “armor.”
To determine how much protection your sunglasses provide, look for markings or labels on the frame. For example, if the frame says UV-400, that means your sunglasses offer 100% protection from UV rays. There is also another marking system with numbers from 0 to 4, where 0 means 5% protection and 4 means 95% protection from sunlight.
We recommend purchasing only high-quality sunglasses, as poor-quality ones are not only unhealthy but can cause even more harm to the eyes by keeping the pupils dilated and allowing much more unfiltered harmful light to enter.
Yes, you can. All you need to do is get a UV flashlight. If the light passes through the lenses, the sunglasses are fake. If it doesn’t, that means you've got yourself a pair of quality sunglasses.
Sunglasses are usually made from either glass or plastic. It's believed that glass lenses are more likely to have UV protection. With expensive models, however, the material doesn't matter much – they are almost always equipped with the necessary filters.
Now let’s look at sunglasses not through the lens of science, but through the eyes of fashion.
In 2026, sunglasses are no longer just a protective accessory. The variety of models is so vast that they have become a symbol of style and individuality. It's rare to see people wearing the same glasses, which truly makes this accessory unique. But let’s take a look at which models stood out this season in the street style scene:
Oversized sunglasses. Lately, I’ve noticed that “big” sunglasses dominate the urban landscape. These are vintage-inspired models, strongly influenced by the 80s or even the 70s, featuring expressive frames and a distinctive sense of freedom.
Geometric shapes. It’s hard to imagine a modern urban look without sunglasses in interesting geometric shapes like hexagons, trapezoids, or diamonds. A bold outfit that exudes character and rebellion. These models are more popular among young people, but you’ll occasionally see older individuals confidently wearing such styles too.
Colored and transparent frames. These models are fantastic and tend to be favored by creative individuals or those in the arts. The variety is vast – pink, mint, beige, and lavender are just some of the trending shades this year.
Monochrome sunglasses. These models, where the frames and lenses are in the same color tone, are gaining popularity. They offer a refined appearance and an unmatched sense of luxury. Most popular are the metal models and those made of glass or similar materials.
Eco sunglasses. Climate change demands urgent action from all of us. Although still not widespread, we hope the trend will shift toward sunglasses made from recycled materials, bamboo, or bio-acetate. An organic material that brings perfect harmony to any outfit and shows the world that you care about the planet’s future.
To choose sunglasses that suit you best, you need to consider your face shape.
If you have a round face, the most suitable models are butterfly-shaped glasses or ones with a narrow nose bridge. Avoid small round frames as they won’t complement your features.
If you have an oval face, we recommend round or rectangular glasses. Avoid overly bulky frames.
If your face is square, go for wide sunglasses; aviator shapes can also be a good choice. You can opt for a colored frame, as it’s likely to suit you.
If your face is rectangular, focus on models that visually widen your face. Large glasses work well for you. Avoid small frames, as they disrupt facial proportions and may look awkward.
Look for a UV-400 marking on the frame or lenses – it provides 100% protection against harmful UV rays.
The easiest way to check the quality of sunglasses is with a regular UV flashlight. If the light passes through the lenses, they don’t offer protection. If the light does not pass through, you can be sure you have a true ally against UV rays.
Yes, for example, a round face pairs best with butterfly-shaped frames or ones with a narrow nose bridge.
Regardless of whether it’s winter or cloudy, always wear protective sunglasses during daylight hours, because UV rays pass through clouds.
Yes, they can cause your pupils to dilate and let in more harmful light instead of protecting your eyes.
