How to Choose the Right Pair of Sunglasses

The best season is getting closer and closer, and nothing says ‘summer’ quite like picking out a new wardrobe. One main staple for everyone’s suitcase this coming sunshine-time is a great pair of sunglasses.

There are several things to consider when deciding what type of shades to add to your collection: how they look, how they protect and how they can improve/optimise your experience. Trespass has it all, so we’ve compiled a guide to help you pick the sunglasses that are going to suit your lifestyle best, without breaking the bank!

Fit For Purpose?

It’s always fun to window shop and see the different styles out there, but it is important to consider what situations, environments and activities you will be in while wearing them. Anyone that has had a pair of sunglasses slip off of their face while partaking in any extreme sport will testify to this.

Are you looking for something suitable for lying on your reclining sun lounger all day or are you going to be flying down a hill at high speeds? Sunglasses are important in both scenarios, but you will need different characteristics to make sure you’re getting the most out of them in each one.

At Trespass, we offer both casual sunglasses and sportswear sunglasses in a variety of styles and designs. They are all made with comfort in mind, to enable you to enjoy yourself no matter how chilled or intense your activities become.

UV Protection

When buying a pair of sunglasses, it is assumed that your intention would be to wear them in the sun (the trick is in the name)! When your skin is exposed to the sun, you use UV protective sunscreen, and your eyes should be no different. UV-protective sunglasses will not only protect your health from degenerative eye disorders and cancers, but it also allows you to make the most of your time outdoors without worrying about glare, clarity and poor visibility.

It is important to remember that although it may not be warm, the sun may still be lurking, so always consider UV protection when planning any kind of outdoor activity. You should always choose sunglasses with a lens category of at least 2 or above as these provide a good level of UV protection and sun glare reduction.

At Trespass, we know how important it is to protect your eyes, and the sensitive skin surrounding them, from the sun, which is why all of our sunglasses come with UV protection.

Lens Categories

The weather differs as much as people do, so it makes sense that sunglasses come with a range of lenses to suit varying conditions and environments. However, there are traditionally five different types of lenses used in sunglasses:

  • Category 0 lenses are clear or have a very faint tint and are used in day to day spectacles, reading glasses and in safety goggles.
  • Category 1 lenses are tinted but should only be used for cosmetic use. They contain no UV protection and therefore should not be used as sunglasses.
  • Category 2 lenses are the most common you will find in sunglasses. They provide good protection from UV rays but don’t have as dark a tint as the category 3 and 4 lenses.
  • Category 3 lenses provide extra protection from UV light and will block out the majority of visible light to protect your eyes. They are recommended for use on mountain ranges when you are closer to the sun and as a result, require a higher level of protection.
  • Category 4 lenses are best being used at higher altitudes but are not to be worn when driving as they are too dark. They are not suitable for use as everyday sunglasses but will protect you from strong UV light.

All Trespass sunglasses are produced with category 2 lenses or above.

Types of Sunglasses

Wrap-around Sunglasses

The wrap-around style of sunglasses may be perceived as less fashionable but they are certainly much more functional. You will benefit from more UV protection around the sides of your face, making them ideal for activities where you rely on your peripheral vision. This style can also appear more ‘sporty’ than traditional sunglass frames, so will help to improve the versatility of your wardrobe.

Fashion-forward Wayfarer Style

Let’s face it, we live in a time of social media, and especially when the sun is out, you want to be looking good in case any candid snaps (and not in a good way) end up online. Trespass has a range of the popular wayfarer-style of sunglasses that offer just as much panache as designer ones, but without the price tag.

Mirrored Lenses

Mirrored lenses are great for reducing glare as they reflect light away from your eyes. They also get bonus points for allowing you to check your hair and can create some great Instagram photos.

We would recommend mirrored lenses for any activity that has the possibility of high-glare, including snow sports, water sports or hiking. They reduce brightness, sharpen details and preserve normal colour balances, so are definitely worth considering if you are looking to optimise your performance in these situations.

Coloured Lenses

Sunglass lenses come in a variety of different shades and colours, and while finding a pair that sets off your outfit is important, there are other benefits to choosing a colourful set of shades.

  • Grey lenses will cut down on the intensity of light without distorting the natural colours you can see. This makes them ideal for driving (you wouldn’t want to mistake a red light for a green light…) and other activities where colours can be important.
  • Green lenses enhance contrast in natural light and can improve depth perception. They help to reduce eyestrain in brighter than normal situations and have been recommended for sports like golf.
  • Yellow lenses enhance the quality of light and increase contrast in low light conditions, such as snow or fog, making them ideal for winter sports. They can, however, cause colour distortion, so are not recommended for cycling or driving.
  • Brown lenses offer a good range of protection in all circumstances. By eliminating brown tones they can enhance contrasts and increase depth perception. These types of lenses are great for golf, tennis or any sport where distance needs to be judged.
  • Pink or red lenses block fuzzy blue rays and can sharpen your vision, making them great for being exposed to sunlight for long periods of time. They limit eyestrain and are known for being comforting to your eyes. As well as protecting you from the sun, they can also help fight the effects of computer screen glare and work great in low light conditions, such as at night or in snow.
  • Blue lenses provide protection that is best suited to moderate sunlight. As well as looking great, they can also help sharpen up your vision and reduce blurriness.

Level up

As great and diverse as sunglasses come, in extreme sport conditions they sometimes just don’t cut it. In situations where you need to take your eye and vision protection to the next level, you should consider investing in a pair of ski goggles.

Whether it is snow debris or glare, your eyes go through a lot on the piste so by giving them proper and efficient protection with a pair of Trespass ski goggles, you won’t have to worry about falling victim to slope conditions.

Ranging in terms of style, function and features, you’ll easily be able to find a pair of ski or snowboarding goggles that suit your needs perfectly meaning you can keep your eyes on the prize. We even have a goggle-buying guide to help you choose the best set of ski goggles for you.

How to Pick the Right Shades For Your Face Shape

It’s no secret that choosing sunglasses can be difficult, purely for the fact that we all have completely different shaped heads and faces, never mind our own tastes and style preferences.

There are four different face shapes – Oval, Round, Heart, and Square – that each have different styles of sunglasses designed to complement them.


An oval face is perhaps the easiest for choosing sunglasses as it’s not particularly angular anywhere, although you should generally choose wide frames that are equal to or larger than the widest part of your face.


Round faces are considered eternally youthful in their features, and the fuller look allows you to play with different kinds of frames that others might not pull off. Angular frames can work to sharpen softer features and balance off the roundness of your cheeks, while narrower frames can create a longer face shape.


A heart-shaped face has high cheekbones and narrow, defined chin. You should go for wider frames that are slightly wider than your forehead and thinner arms for enhanced face symmetry.


Square faces are angular and strong, meaning that rounder frames are usually advised to complement and soften your features. The fact that rounder frames suit you lets you play around with different styles of frames, from cat-eye to super-wide frames or classic Ray-Ban-esque rimless styles.
