How to choose sunglasses: finding the right pair for everyday wear, sport and travel

Buying a pair of sunglasses might seem straightforward, until you realise that models vary significantly in fit, lens quality and ease of use. A frame that feels comfortable in the shop can slip when you’re cycling. A fashionable pair might not give you enough information about UV protection. And a cheap pair of sunglasses for driving can actually make annoying reflections more visible.

As a Joybuy Product Recommendation Officer, I filter product information by verifiable features. This way, you avoid relying solely on colour, brand name or a flashy advertising claim.

Three common pitfalls when buying sunglasses

1. Only looking at the appearance

A pair of women’s sunglasses or men’s sunglasses should of course suit your style, but the frame also determines how comfortable they are to wear. Pay attention to the width of the frame, the length of the arms and the shape of the nose bridge. A model that’s too loose will slip when you’re walking or cycling; one that’s too tight can feel uncomfortable after a while.

2. Confusing “UV protection” with UV400

The term UV400 sunglasses refers to protection against ultraviolet light up to 400 nanometres. Check that this is clearly stated in the product specifications. A dark lens on its own is not proof of adequate UV protection. For the models below, the protection claims come from the manufacturer’s product information.

3. Considering polarisation without thinking about the application

Polarised sunglasses can reduce reflections from roads, water and metal surfaces. This is practical when cycling, walking and driving. However, the effect can vary depending on the situation. Some displays, such as LCD screens in cars or navigation systems, may be less clear when viewed through a polarised lens. So always test that your dashboard and phone remain easy to read.

Important specifications to check

UV400 and lens category

First, look at the stated UV protection, then at the tint of the lens. A light or photochromic lens can be more convenient in changing weather. According to the product description, the OutdoorMaster HawkSharp uses photochromic lenses that change from category 0 to category 3 based on UV exposure. This makes this type interesting for cyclists who ride in both cloudy and sunny conditions.

For direct sunlight or special situations, such as viewing a solar eclipse, ordinary sunglasses are not suitable. Damaged or heavily scratched lenses should be replaced.

Material and weight

A lightweight pair of sunglasses is especially pleasant when you wear them for longer periods. TR90 is a thermoplastic material used in several models in this selection. Also check the total weight. According to the product information, the Beneunder FD421 weighs 26 grams; the Revoray X3-blue around 30 grams and the Revoray Y1-black around 33 grams.

For sport, non-slip nose pads and sturdy arms are also important. An aerodynamic shape can also help reduce wind pressure when cycling, but it doesn’t automatically make a pair suitable as professional safety eyewear.

Fit and dimensions

Don’t just look at “one size”. Check the frame width, bridge width and arm length. For the Ray-Ban Meta Wayfarer Gen1 AI Glasses, for example, size 53-22 is stated: a lens width of 53 millimetres and a bridge of 22 millimetres. The smaller version of the Ray-Ban Meta glasses has size 50-22.

Sunglasses to wear over prescription glasses need to offer enough room without pressing against your frame or cheeks. Ideally, measure your current glasses and compare the dimensions with the product page.

Frequently asked questions about sunglasses

Are polarised sunglasses suitable for driving?

They can be, especially when reflections on a wet road are annoying. Do check that your dashboard, navigation screen and traffic information remain clearly visible. A polarised lens is not automatically a replacement for specific safety eyewear.

How long do sunglasses last?

The lifespan depends on use, impacts, heat and care. Store your glasses in a hard case, clean the lenses with water and a soft cloth, and don’t leave them in a hot car for long periods. Replace your glasses when the lens is heavily scratched or the frame is no longer stable.

Can I wear sunglasses over my ordinary glasses?

Yes, fit-over models exist for this purpose. Measure the width and height of your current frame and check that the over-glasses have enough room. Also pay attention to the weight: a combination of two frames can put more pressure on your nose and ears.
