With the increase in daylight hours and the arrival of the spring-summer season, sunglasses take centre stage. They are not just an aesthetic accessory, but an essential health tool for our daily wellbeing.
Finding the perfect balance between an attractive design, complete comfort and maximum eye safety may seem complicated. However, once you understand the basics of light filtering and pay attention to the materials, choosing the right pair becomes much easier.
This guide is designed to help you choose the best sunglasses, ensuring your eyes are protected while you enjoy the good weather in style.
Why choosing the right sunglasses matters more than it seems
Often, the decision to buy this accessory is based exclusively on fashion trends. However, the impact of a poor choice goes far beyond aesthetics.
Prolonged exposure to sunlight without proper protection can cause eye strain, dryness and, in the long term, irreversible damage to the retina or crystalline lens.
Quality sunglasses act as a protective shield against ultraviolet radiation. They also improve visual contrast, reduce annoying glare on surfaces such as asphalt or water and relax the facial muscles, helping you avoid straining your eyes or constantly frowning on the brightest days.
What protection should good sunglasses have?
The main function of any tinted lens should be to block harmful radiation. To make sure a model is safe for daily use, especially during summer holidays, you should always check two essential technical specifications.
What does UV400 mean?
The UV400 certificate is the main standard in eye protection. It means that the lenses have been treated to block all ultraviolet rays, both UVA and UVB.
This is the highest protection available against solar radiation. Going without this filter means that the pupil, being in a darker environment created by the lens, dilates and absorbs an even greater amount of radiation than if you were not wearing sunglasses, which can be extremely harmful.
What does a category 3 lens mean?
The category of a lens, from 0 to 4, does not measure ultraviolet protection, but the amount of visible light that is allowed to pass through to the eye. A category 3 lens absorbs between 82% and 92% of ambient light.
This opacity makes it the optimal and most recommended option for bright conditions, such as very sunny days, trips to the beach, mountain walks or everyday driving.
Sunglasses for men and women: what to look for before buying
Beyond lens safety, the frame plays a decisive role in your wearing experience. For sunglasses to become your summer favourites, they should meet three essential requirements.
Comfort and lightness
No matter how attractive a design is, if it feels heavy or puts pressure on the bridge of your nose and temples, you will eventually stop wearing it.
Lightness is a key factor. Frames should rest gently on the face, allowing you to wear them for hours without leaving marks or causing headaches.
Frame material
The manufacturing materials determine the durability and flexibility of the accessory. It is advisable to choose frames made from resistant polymers that can withstand temperature changes, exposure to sea salt and continuous use outdoors.
A good material ensures that the sunglasses do not deform and keep their original fit season after season.
Style and versatility
The design should adapt to the shape of your face and your lifestyle. Clean-lined silhouettes with balanced proportions are usually the most flattering for most face shapes. Choosing a versatile aesthetic ensures the accessory will not look out of place, whether you are wearing a casual outfit or something more sophisticated.
How to choose sunglasses by colour
The shade of the frame is the statement of intent behind your look. The wide range of colours allows you to adapt this accessory to your personality and to the colour palette of your summer wardrobe.
Blue sunglasses
Blue sunglasses, especially in navy or indigo tones, bring an instant sense of freshness. It is a very nautical shade that pairs perfectly with denim garments, white linen shirts and coastal-inspired looks.
It feels less severe than black and softens the features, making it an excellent option for both men and women.
Sunglasses in neutral tones
Colours such as tortoiseshell, khaki, black, grey or taupe are true wardrobe essentials. They bring elegance and sobriety and ensure the accessory matches impeccably with any garment, from a lightweight linen suit to swimwear. If you are looking for a safe and timeless option, neutrals never fail.
Bold colours for summer looks
Summer is the ideal time to introduce bold touches of colour. Frames in shades such as mustard, red or green become the focal point of monochrome or minimalist outfits. They are the perfect alternative for adding vitality, energy and a relaxed character to your holiday days.
How to style men’s and women’s sunglasses in spring and summer
Adding this accessory to your everyday outfits, or choosing it as a Mother’s Day gift, is very simple if you pay attention to material harmony and personal taste. During the warm months, lightweight, clean-lined sunglasses pair exceptionally well with natural fibre garments.
A mustard-coloured model can stand out alongside a floaty cotton dress, while navy blue sunglasses can be the perfect finishing touch for a look with Bermuda shorts and boat shoes.
The secret lies in balance. If your clothing has bold prints, choose neutral sunglasses. If you are wearing basic garments, let the colour of the frame take centre stage.
Frequently asked questions about sunglasses
Which sunglasses offer the best protection?
The sunglasses that offer the best protection are those that are certified with a UV400 filter. This ensures your eyes are fully protected from ultraviolet radiation. The colour of the lens or frame does not affect UV protection, but rather visual comfort in bright light.
What does it mean when sunglasses are UV400?
It means that the lenses can block 100% of ultraviolet rays, both UVA and UVB, up to a wavelength of 400 nanometres. This is the highest filtering level and is essential to avoid eye damage from direct sun exposure.
Which lens category is best for summer?
For the spring and summer months, category 3 is the most suitable. Lenses at this level absorb the right amount of visible light to prevent glare in very sunny environments, such as the beach or the city, allowing clear and relaxed vision without making the surroundings excessively dark.
Do coloured sunglasses go with everything?
Yes, when used strategically. Frames in bright colours such as mustard yellow or light green are ideal for adding a touch of contrast to outfits made up of neutral tones such as white, beige or grey. They work as the perfect accent that elevates a basic look and turns it into a carefully styled summer outfit.
