Buying glasses: how to choose the right pair for everyday wear, reading or travel

Buying glasses online may seem straightforward, but product photos and marketing terms don’t always tell the whole story. If you focus only on appearance or a low price, you could end up with a pair that doesn’t fit well, isn’t compatible with your phone or isn’t suitable for the way you plan to use it.

When buying glasses, there are three main pitfalls to watch out for:

  • A good-looking fit without checking the measurements: glasses that are too wide or heavy may slip down your nose or press behind your ears.
  • Confusing tint with protection: dark lenses don’t automatically provide UV protection. Look for a clear specification such as UV400 and check the product information.
  • Smart features without checking compatibility: AR or AI glasses may rely on USB-C DisplayPort, an app, Android, iOS or a wireless connection. Check before you buy.

What should you look for when buying glasses?

1. Fit, weight and dimensions

Your glasses should stay in place without putting you under much pressure. So check the frame width, arm length, bridge width and weight. A lightweight pair is often more practical for extended wear, but low weight alone doesn’t mean the shape will suit every face.

For sports glasses, non-slip nose pads and sturdy arms are useful features. With reading glasses, it’s important that the lenses sit straight in front of your eyes. Foldable sunglasses are handy for travelling, but pay extra attention to the hinge and how they’re stored.

2. Lens type and protection

Sunglasses marked UV400 are designed to filter ultraviolet light within the relevant range, according to the product specifications. Also check whether the product information mentions coatings, scratch resistance and light transmission.

According to the product description, polarised sunglasses can reduce reflections from surfaces such as wet roads, water and metal. This can be useful when cycling or enjoying outdoor activities. However, they may affect how easy some LCD screens are to read, so always check whether a pair is suitable for driving.

For cycling and other high-intensity activities, practical specifications include impact-resistant polycarbonate lenses, a secure fit and a wide field of vision. Don’t use reading glasses or ordinary sunglasses as safety glasses.

3. Connections and software for smart glasses

Smart glasses, AR glasses or AI glasses can offer a range of features, such as a large virtual screen, music, calls, translation, photos or access to ChatGPT. However, features vary significantly between models.

Before you buy, check:

  • Do you need a phone, computer or handheld device?
  • Will the glasses work with your Android or iOS device?
  • Is USB-C DisplayPort required?
  • Do you need to install a separate app?
  • How long does charging take, and how long can you use the glasses?
  • Are the glasses water-resistant, or should you keep them away from water and extreme temperatures?

For translation glasses, also check the supported languages, any usage limits and whether an internet connection is required. The features listed are based on the product listings and aren’t necessarily backed by independent research.

Frequently asked questions about buying glasses

Which glasses are suitable for reading?

Reading glasses with the right strength are designed for close-up text. A fixed strength can be practical, but don’t use standard reading glasses as a substitute for a personalised eye test or if you have ongoing vision problems. For example, a pair with +2,00 is only suitable if that strength works for your reading distance.

Can I use smart glasses with any phone?

Not always. Some models work via a dedicated app and Bluetooth, while AR glasses may need USB-C DisplayPort to display images. So check the list of compatible Android, iOS and computer devices before you order.

How do I care for sunglasses or cycling glasses?

Gently rinse off any dust with water first, then use a soft microfibre cloth. Avoid harsh cleaning products, high temperatures and storing them loose among hard objects. Keep foldable sunglasses in a protective case and check the hinges, nose pads and lens coating regularly.
