Buying Sunglasses: How to Choose the Right Pair for Everyday Use and Sport

Buying a pair of sunglasses might seem straightforward, but marketing jargon can make comparing them trickier than you’d think. A dark lens, for example, doesn’t automatically mean the glasses offer adequate UV protection. Similarly, “polarised” mainly refers to glare reduction, not UV protection in itself.

For everyday use in the UK – whether you’re driving, cycling or travelling – there are three key pitfalls to watch out for:

  • A stylish, dark lens with no clear UV specification: always check whether the product information mentions UV400 and whether relevant conformity details are available.
  • Confusing polarisation with full protection: a polarised pair of sunglasses can reduce glare from wet roads, water or glass, but you still need to check the UV specification separately.
  • Overlooking fit and intended use: a pair that slips when you’re cycling or gets damaged in a coat pocket won’t be practical. Weight, nose pads, temple arms and a protective case all matter.

Which Specifications Should You Look Out For?

1. UV400 and European Product Information

UV400 refers, according to the product description, to protection against UV radiation up to 400 nanometres. When buying, don’t just rely on a sticker or a sales title – check the technical details of the model. The product information supplied for the OutdoorMaster and Beneunder models mentions UV400. Some OutdoorMaster models also include CE information.

A CE mark is not a quality rating. It is a declaration of conformity and should be considered alongside the product information, warnings and details of the responsible party in the EU. Do not use ordinary sunglasses for looking directly at the sun, a solar eclipse, welding or laser radiation.

2. Polarisation, Photochromic Lenses and Driving

A polarised pair of sunglasses is particularly useful when glare is an issue – for example, on water, tarmac or cycle paths. According to the product description, the OutdoorMaster Hawk II uses polarised TAC lenses with a UV400 specification. The Hawk LT combines polarisation with photochromic technology.

A photochromic pair of sunglasses adjusts its tint according to UV exposure, according to the product description. This is handy when you’re moving between shady and sunny conditions. However, if you’re buying sunglasses for driving, there’s an important limitation: the windscreen can block UV radiation, meaning a photochromic lens may not darken as much inside the car. For drivers, a predictable lens colour is often more practical.

3. Weight, Material and Fit

A lightweight pair of sunglasses reduces pressure on your nose and ears during long walks, bike rides or trips. TR90 is a thermoplastic frame material mentioned in the product descriptions of several models. The models listed weigh approximately 26 to 29 grams, depending on the version.

Also check:

  • frame width and temple length;
  • adjustable nose pads or soft nose grips;
  • anti-slip material for sports use;
  • a glasses case and cleaning cloth;
  • whether the glasses can be folded;
  • lens colour and visibility in overcast weather.

A foldable pair of sunglasses is handy for a bag, glovebox or hand luggage. However, hinges are a point to watch: fold the glasses gently in the intended direction and store them in a case.

Frequently Asked Questions About Sunglasses

Is a UV400 pair of sunglasses suitable for everyday use?

A UV400 pair of sunglasses is intended, according to the product information, to block UV radiation up to 400 nanometres. Always check the official specifications, warnings and conformity information for the specific model. Do not use the glasses for looking directly at the sun or for tasks that require specialist eye protection.

Is a polarised pair of sunglasses useful for driving?

Polarisation can reduce glare from the road surface, water and other smooth surfaces. This can be pleasant when driving, but check whether the lens is suitable for your vision and conditions. A photochromic lens may not darken as much behind a windscreen, because the windscreen blocks some UV radiation.

How do I care for my sunglasses so they last longer?

Rinse off dust gently if possible, use a soft microfibre cloth and avoid harsh cleaning products. Store the glasses in the supplied case or pouch and do not leave them in high temperatures for long periods, such as on the dashboard. Replace a pair when the lens is badly scratched or damaged – damage can affect your vision.
