Foldable UV400 sunglasses are handy if you often switch between cycling, driving, sitting outside and travelling by train in the Netherlands. They’re easier to slip into a coat pocket or small bag than a traditional pair. But a compact design doesn’t automatically mean a good fit, effective protection or long-lasting quality.
Look out for these three common pitfalls:
When choosing sunglasses with UV protection, UV400 is an important detail to check. Also look at the lens material and any coating listed. According to the product description, the Beneunder FD421 has high-definition nylon lenses with a UV400 coating. The manufacturer claims that the model blocks at least 99.9% of UV radiation.
Treat this manufacturer’s claim as information from the product description, not as a general guarantee for every similar model. When buying, also check the latest product specifications, the information supplied with the product and any conformity markings.
Anti-glare sunglasses may be useful when dealing with reflections from wet roads, shop windows or the dashboard. The Beneunder FD421 has an OAR anti-reflective coating. According to information from Beneunder, this coating reduces glare by at least 99.6%.
A good fit is still important when driving. Oversized sunglasses shouldn’t unnecessarily restrict your peripheral vision, and they should stay securely in place when you turn your head. So check the frame width, bridge and arm length. Never use sunglasses as a substitute for good vision or the correct prescription lenses.
Lightweight sunglasses are more comfortable to wear for long periods. The FD421 weighs 26 grams according to the product specifications and has a TR90 frame. TR90 is a lightweight, flexible plastic often used for glasses and sports accessories. However, the properties of a particular frame depend on its construction and finish.
According to the product information, the FD421’s tri-fold design folds down to around 35 millimetres thick. This makes it a good compact pair of sunglasses for travelling. If you’re considering a folding pair, bear these practical points in mind:
Why it suits this profile: This model combines an oversized shape with a foldable design, UV400 lenses and a weight of 26 grams. The black colour is easy to pair with everyday outfits.
The product information gives specific details about the frame weight, folded size and UV400 coating. This means you can check these features rather than judging the sunglasses on looks alone.

Why it suits this profile: The Boston shape offers a classic alternative to oversized sunglasses. According to the product description, the model has adjustable arms and butterfly nose pads, which can be useful if a standard fit doesn’t feel right.
As well as UV400 protection, the product information lists anti-reflective, oil-repellent and scratch-resistant coatings. This gives you more detail than a general claim about durability.
TR90 frame, nylon lenses, adjustable arms and multiple lens coatings, according to the stated product specifications.
Why it suits this profile: If you travel often, spend time outdoors or regularly keep sunglasses in the car, you’ll appreciate the slim folding design and lightweight construction. The tea-brown version is a stylish choice that works with a range of outfits.
The product description lists both the weight of 26 grams and the compact folded size. This helps you assess how portable they’ll be before buying.

We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and the applicable European safety requirements.
UV400 is an important indication of protection against UV radiation up to 400 nanometres. Also check the product information, lens category and conformity details. Dark lenses without suitable UV protection aren’t a good choice.
They can be, provided they fit well and don’t obstruct your vision. According to the manufacturer, an anti-reflective coating can help reduce glare, but always check that the model doesn’t cause distracting changes in colour or distortion. Check the fit while stationary first, and always take the traffic conditions into account.
Use a soft microfibre cloth and keep the sunglasses in a case when you’re not wearing them. Avoid paper tissues, rough fabrics and cleaning products that aren’t designed for glasses lenses. Fold them carefully and touch the lenses with your fingers as little as possible.
