Choosing sunglasses: how to find a comfortable pair for every situation

Sunglasses are not just a fashion accessory. Whether you wear them every day, while driving, cycling or travelling, the quality of the lenses, fit and portability determine how much you get out of them. A low price may seem appealing, but a poorly fitting frame, unclear UV information or lenses that scratch easily can make your purchase less practical.

This buying guide helps you compare sunglasses based on verifiable features. That way, you can make an informed choice between folding sunglasses, sports sunglasses, polarised sunglasses, or a stylish cat-eye or oversized pair.

Three common pitfalls when buying sunglasses

1. Looking only at the colour or shape

Cat-eye sunglasses, oversized sunglasses or a classic square frame may suit your style, but that says nothing about comfort. Also consider the frame width, nose bridge and temple length. A frame that is too wide may slip while cycling; a pair that is too narrow may put pressure on your temples.

2. Confusing UV400 with reduced glare

UV400 protection and polarisation are different features. UV400 refers to protection against UV radiation up to 400 nanometres. Polarisation is designed to reduce distracting reflections, for example from wet tarmac, water or glass. So sunglasses with UV400 protection are not automatically polarised sunglasses.

Claims such as “blocks 99.9% of UV radiation” come from the brand’s product information. According to Beneunder’s own information, several models offer UV400 protection; according to OutdoorMaster’s own information, the sports models mentioned have UV400 lenses. Always check the current product specifications before buying.

3. Assuming a folding design is indestructible

Folding sunglasses are handy in a jacket pocket, handbag or hand luggage, but hinges are still components that need to be handled carefully. Fold the frame gently in the intended direction and store it in a pouch or case. Lightweight sunglasses are more comfortable to wear for long periods, but lightweight does not mean that the model is suitable for every intensive activity.

Which specifications are important?

UV400, lens category and brightness

First, check whether the product page clearly states UV400 protection. A darker lens may be more comfortable in bright sunlight, while a clear or lighter lens is better suited to cloudy conditions. The OutdoorMaster Hawk HD comes with a grey polarised lens and a clear interchangeable lens. According to the product information, the model has a VLT of 18% for the coloured lens.

Please note: sunglasses are not designed for looking directly at the sun, a solar eclipse, welding arcs or laser radiation. Damaged or heavily scratched lenses should be replaced.

Polarisation and photochromic lenses

Polarised sunglasses can reduce glare from horizontal surfaces. This can be useful when driving, boating, fishing or cycling. However, it does not guarantee that every view will be more comfortable for every user. Also check that your navigation screen or dashboard remains easy to read.

Photochromic sunglasses adjust their tint according to the amount of UV light, as stated in the product information. The OutdoorMaster Photochromic Cycling Glasses are listed as Cat.0 to Cat.3. In a car, the effect may be limited because the windscreen blocks some UV light. If you are mainly looking for sunglasses for driving, it is therefore worth comparing them with a standard tinted or polarised pair.

Frame material, weight and fit

TR90 is a thermoplastic material described in the product information for several models as lightweight and flexible. Also check the stated weight and dimensions. According to the product specifications, the Beneunder Boston FD01h weighs 0.97 oz, approximately 27.5 grams. The Beneunder FD421 is listed with a weight of 26 grams and a folded thickness of 35 mm.

Pay particular attention to:

  • Frame width: should suit your face without extending too far beyond it.
  • Nose bridge: should not keep slipping or feel tight.
  • Temples: should stay securely in place without putting pressure behind your ears.
  • Hinges: on folding sunglasses, they should feel smooth but not loose.
  • Lens coating: anti-reflective, oleophobic and scratch-resistant coatings can make everyday care easier, but they are not scratch-proof.

Care and lifespan of your sunglasses

Sunglasses generally last longer when you do not leave them loose in a bag. Use a hard case for sports, travelling or commuting. Carefully rinse off sand and dust before cleaning the lenses. Use a soft microfibre cloth and avoid harsh cleaning products.

Take extra care with the hinges on folding sunglasses. Do not force the frame, and do not leave it in a hot place for long periods, such as a car dashboard. Before each outdoor season, check whether the lenses are badly scratched and whether the frame still sits securely.

Frequently asked questions about sunglasses

Is UV400 protection sufficient for everyday use?

UV400 is an important specification to look for. Also check that the sunglasses fit well, are undamaged and are suitable for the amount of light in which you will use them. Dark lenses without clear UV information are not a sensible choice.

Are polarised sunglasses suitable for driving?

They can be, especially if you are bothered by reflections from wet roads or other surfaces. However, test whether your dashboard and navigation screen remain easy to read. With some screens, viewing angles and coatings can affect the display.

How do you care for folding sunglasses?

Fold the frame gently according to the hinge design, clean the lenses with a microfibre cloth and store the sunglasses in a case. Do not leave them loose next to keys or other hard objects. Replace the sunglasses when the lenses are badly scratched or the frame no longer fits properly.
