Buying smart glasses in the UK: what actually matters

Buying smart glasses in the UK starts with choosing what you want them to do. Some focus on audio or camera capture; others add a display so you can read information in view. AI features vary between models, so check the particular functions you need.
SightPhones sells Rokid Glasses, smart glasses with a private display for supported captions, translation and prompts. This guide explains the practical questions to ask about display glasses, from fit and battery life to phone compatibility and UK support.
For a closer look at the feature differences, compare audio, camera and display smart glasses.
Weight
Weight is one part of comfort. Frame shape, nosepad position and how clearly you can read the display also matter. Fit varies between wearers, so a specification alone cannot tell you whether a pair will feel comfortable for several hours.
Rokid lists the glasses at 49g. Check fit and reading comfort as well as weight before choosing them.
Display brightness
For glasses with a display, check how readable the text is in the conditions where you plan to use them. Brightness is useful to compare, but it does not by itself guarantee outdoor readability. Ambient light, fit and display position also affect the experience.
Rokid lists display brightness of up to 1,500 nits. Treat that as a manufacturer specification, rather than a promise of readability in every outdoor setting.
Battery life
Battery life varies by task. Rokid lists around 45 minutes of intensive recording and 5 to 6 hours of music playback. Actual use depends on settings and conditions. The Power Cells accessory includes two removable rechargeable batteries and a compact charging box. A capsule battery attaches to the charging contacts on the glasses arm.
Phone compatibility
Pair through the Hi Rokid app with a compatible phone. Rokid currently recommends iOS 16 or later or Android 12 or later.
Prescription support
If you normally wear prescription glasses, confirm before buying whether a prescription lens service is available. Not all manufacturers offer one. SightPhones offers a prescription service for single vision prescriptions. For full details, see Can smart glasses work with prescription lenses?
Warranty and returns in the UK
Electronics sold in the UK carry statutory protection under the Consumer Rights Act 2015. The relevant question is who handles warranty claims: whether you are dealing with a UK-based retailer or with an overseas manufacturer's support team. The difference in practice can be significant.
SightPhones handles warranty and returns directly from the UK, with a one-year manufacturer's warranty and a 30-day return window subject to the published returns terms.
What to ignore
Marketing language about “AI” in this category is often vague. The useful question is not whether a product calls itself AI glasses, but what specific AI features it actually runs: translation, transcription, object recognition, or something else. The more specific the feature description, the more credible the claim.
Where things stand
Display-based AI glasses are genuinely useful for a specific set of people: frequent travellers, those who work in multilingual environments, people who navigate unfamiliar places regularly, and those who want a calmer relationship with information than a smartphone offers.
They are not for everyone yet. The form factor still announces itself as technology rather than disappearing into everyday dress. Battery life depends on the task. The ecosystem of apps and features is still developing.
But they work. For the right use case, they work quite well.
