Which sunglasses are right for you? Look out for UV400, polarisation and comfort

Buying sunglasses seems simple until you have to choose between sports sunglasses, oversized sunglasses, cycling glasses or a foldable model. Marketing terms such as “HD”, “anti-glare” and “photochromic” only mean something when you know which specifications go with them.

For everyday use in the Netherlands, three things are particularly important: protection against UV radiation, reduced glare and a fit that remains comfortable even after several hours. Below, you can find out what to look for and which models suit different situations.

Common pitfalls when buying sunglasses

1. Confusing UV400 with a dark lens

A dark lens does not automatically block UV radiation. Look for an explicit mention of UV400 protection in the product information. According to the descriptions of the models mentioned, UV400 refers to protection against UV radiation up to 400 nanometres. Always check that this information is clearly stated for the product before buying.

Dark sunglasses without the right protection can also be less comfortable in changing light conditions. The colour of the lens is therefore no substitute for a technical specification.

2. Seeing polarisation as the answer to every situation

Polarised sunglasses can reduce reflections from wet tarmac, water and metal surfaces, for example. This is useful when cycling, walking or travelling. However, polarisation is not always suitable for every application. Contrast can appear differently on some displays, while for driving, good light transmission and clear vision are particularly important.

Also check whether a model is suitable for use behind a windscreen. Photochromic sunglasses may not become dark enough in a car because the windscreen blocks some UV radiation.

3. Choosing based only on appearance and weight

Oversized sunglasses or cat-eye sunglasses may suit your style, but their dimensions also affect how the frame sits on your face. Glasses that are too wide can slip, while a narrow nose bridge can cause pressure. Pay attention to the frame width, nose bridge, temple length and weight.

Lightweight sunglasses made from TR90 may be worth considering for long days, but also check whether the nose pads and temples provide enough grip. With foldable sunglasses, sturdy hinges and a protective case are particularly important.

Important specifications explained

UV400 protection

Look for a clear mention of UV400 and check that this information forms part of the official product description. For the models below, percentages and certifications are stated by the brands or sellers. They should therefore be presented as product information, not as independently verified results.

Also take note of any warnings. None of these sunglasses is intended for looking directly at the sun, observing eclipses, welding or high-impact work, unless specifically suitable eye protection is stated.

Polarisation and light transmission

Polarisation is particularly useful for reducing distracting reflections. For cyclists, this can be helpful on roads, cycle paths and near water. According to the product description, a sports model with visible light transmission of around 15.2% is designed for bright, sunny weather. In overcast conditions or at dusk, a lighter or interchangeable lens may be more practical.

For sunglasses for driving, it is sensible to choose good visibility, a secure fit and a lens that is not too dark. Never assess a new pair of glasses on style alone; also check that road signs, mirrors and the dashboard remain clearly visible.

Material, fit and comfort

TR90 is a thermoplastic material used in various models because it combines low weight with flexibility. This does not mean that every TR90 frame offers the same quality or fit. Look at the overall weight, adjustable nose pads, non-slip sections and dimensions.

For cycling and running, cycling glasses should stay securely in place while you move. Sports sunglasses with a curved lens can also provide greater protection at the sides, but check that the frame does not touch your eyelashes or cheeks.

Frequently asked questions about sunglasses

Is UV400 enough for everyday use?

UV400 is an important specification to check when you are looking for UV protection. Also consider the product information, fit, lens colour and usage restrictions. Sunglasses are not automatically suitable for observing eclipses, welding or heavy-impact work.

Are polarised sunglasses suitable for cycling?

They can be useful for reflections on tarmac, water and metal surfaces. Check that the glasses stay securely in place and that you maintain sufficient contrast in changing light conditions. For cycling at dusk, a lighter lens may be more suitable.

How long do sunglasses last?

Their lifespan depends on use, hinges, coatings and storage. Keep the glasses in a hard case, clean the lenses with water and a soft cloth, and avoid harsh cleaning products. Replace the sunglasses when the lenses are deeply scratched or damaged; damage can impair your vision.
