Although bars, theaters, and restaurants in central London may seem like ordinary places, owners of many establishments are facing serious issues due to a new device that some consider potentially dangerous—smart glasses.
These glasses can record video, photos, and audio from the user's perspective, and their popularity is growing. Eyewear giant EssilorLuxottica, which collaborates with Meta on manufacturing the glasses, reported that seven million pairs of AI glasses were sold in 2025. According to The Information, at the upcoming Connect conference, Meta plans to introduce new camera-free smart glasses. Samsung and Google are also expected to unveil jointly developed smart glasses this autumn.
However, as this technology spreads, negative reactions are intensifying. Videos on social media showing men who appear to be filming women without their knowledge have raised questions about consent and whether existing privacy laws can keep up with technologies that allow people to record almost unnoticed.
Irina Raiku, Director of the Internet Ethics Program at the Markkula Center for Applied Ethics at Santa Clara University, previously told CNN: 'It is becoming increasingly difficult to protect yourself just by looking around and filtering things out. Thus, the entire concept of consent begins to fall apart.'
London, along with New York and Australia, is becoming an indicator of how society and business are reacting to technological development. Some hospitality and entertainment venues have introduced restrictions or outright bans, and advertising signs against smart glasses have appeared in some bus stops across London. One such sign mocks Kylie Jenner's advertising campaign for Meta glasses, depicting her as a skeleton on an X-ray with the slogan: 'We are always watching.'
This sentiment reflects a broader ban across Great Britain, introduced in August, prohibiting the use of smart glasses in courts. Some London residents told CNN that smart glasses cause them discomfort in places where people expect a certain degree of privacy, such as bars, restaurants, and other social settings.
The popular pub chain Wetherspoons has banned patrons from using glasses for recording. Zac, a student at the Wetherspoons pub in central London, told CNN: 'I don't want to be filmed when I'm just having a couple of pints.' He added that he had seen videos on TikTok where people seemed unaware they were being recorded, calling the recording LED coverage 'absurd.'
Serena, another Wetherspoons patron, expressed particular concern about the possibility of being filmed without knowledge and where the recording might end up. A Wetherspoons representative told CNN: 'Regarding Meta glasses, our instinct was to say: 'turn off the cameras.''
Meta claims that the camera on its glasses will not record if the recording LED is covered. In August, the company announced an update to its glasses to prevent users from attempting to cover the light after recording had started, after the glasses could previously detect if the light integrity was compromised. Meta also stated that it is preventing the spread of videos on social media where users use their AI glasses to stalk others.
A Meta representative stated in a statement to CNN: 'Of course, some places should not be filmed at all, and that is reasonable, but rules must be applied consistently. Our glasses have a light that turns on to notify people that a photo or video has been taken, which smartphones and other cameras do not have.'
Google had previously addressed this issue. More than ten years ago, the company attempted to popularize smart glasses with its now discontinued Google Glass, which sparked similar privacy concerns. Sameer Samat, Google's President of the Android Ecosystem, said that the company is not surprised by the recent pushback. He noted to CNN in August that details such as how the glasses signal recording and whether users can bypass these safeguards are 'truly, truly important,' and that Google takes these concerns into account when developing its glasses. Like Meta's glasses, future Samsung glasses running on Google software will have an interference-resistant privacy LED.
Samsung and Google declined to comment on CNN's inquiry.
According to Callie Schroder, Director of the AI and Human Rights Program at the Electronic Privacy Information Center (EPIC), solving the privacy issue will be complex. Many potential solutions—such as automatic blurring of people's faces during recording or requiring their legal consent before uploading videos—will be difficult to implement and still unable to completely eliminate risks.
One possible method is configuring the glasses to determine their location and automatically disable recording in sensitive areas, such as playgrounds and changing rooms. However, this would require the glasses to have autonomous environmental perception, which could also raise privacy issues.
At the Piccadilly Theatre in London, staff and audience members noted that smart glasses could undermine the experience of a live performance and negatively affect actors' livelihoods. Bradley, a waiter and theatre director, noted that much of the appeal of attending theatres lies in the performance remaining a mystery until the start, which could be threatened by covert filming.
A representative from ATG Entertainment, which manages several iconic West End theatres in London, told CNN that audiences would be asked to remove their glasses and delete any recordings if found with them.
The UK Cinema Association (UKCA) reported at the end of last month that many cinemas in the UK are also banning the use of smart glasses due to piracy concerns.
The growing concern comes amid technological companies continuing to invest heavily in wearable devices, betting that glasses capable of capturing and processing the user's surrounding world could become the next major consumer platform.
These glasses allow users to listen to music, take calls, and take pictures without using their hands, and some tech companies believe they could become the preferred way to interact with AI assistants in the future. A Meta representative told CNN that their glasses allow people to 'stay in the moment, from listening to music to live translation or wireless calls.' He added that the glasses provide a 'critically important new technology' for people with visual impairments, and restricting their use would be a 'serious step backward.'
Advocacy groups, including the Royal National Institute of Blind People (RNIB), warned that excessive regulation of smart glasses could deprive people with visual impairments or low vision of an important accessibility tool. According to RNIB, the new technology could help with daily tasks such as viewing menus in a restaurant, reading road signs, or describing a landscape.
According to research firm Counterpoint Research, the shipment volume of smart glasses grew by 212% year-over-year in the first half of 2026, with Meta leading the market with approximately an 84% share. Schroder, Director of Human Rights at EPIC, believes: 'I think there is a huge fear of falling behind in the race of these new technologies. I also think that tech companies find it very easy to get into a bubble.'
