Should Event Organizers Ban Smart Glasses From the Show Floor?

Ask any conference organizer what belongs on a banned-items list and, until recently, you got the same answer every time: no drones over the crowd, no professional cameras without a media badge, no recording a session without asking the speaker first. That list has a new entry now. In the past seven months, DEF CON, a UK Comic Con operator, the New York state court system, and the U.S. Air Force have each banned Meta-style smart glasses that record video and audio without giving anyone nearby a visible sign that a camera is on. None of these four coordinated with each other. They arrived at the same conclusion on their own, which is usually a sign that a problem has outgrown any single venue.

What DEF CON Actually Banned

DEF CON 34 ran August 6 to 9 in Las Vegas, and its organizers went further than most: recording-capable smart glasses are prohibited altogether, with no exception for prescription lenses Meetings Skift, Should Meta Glasses Be Banned at Meetings?. Attendees who need corrective lenses were told to pack a regular pair for the show, and anyone who wants photos has to use a device people can actually see, like a phone, and ask permission first The Register, DEF CON bans Meta-style 'pervert glasses'. Covert filming is treated as a Code of Conduct violation, not a minor courtesy issue, which at a hacker conference built around a culture of consent and disclosure says something about how seriously the organizers take it CSO Online, Wearing smart glasses to a security conference is not a smart idea.

Four Bans, Seven Months, No Coordination

DEF CON is the most recent, but it is not the first. UK Comic Con organizer Monopoly Events banned the same category of device earlier this year after celebrity guests and their agents said they felt covertly filmed at meet-and-greets, with some warning they might stop doing in-person appearances altogether if the practice continued The Register, DEF CON bans Meta-style 'pervert glasses'. New York went further still: as of July 20, 2026, smart glasses with cameras, microphones, or recording capability are barred from all 1,240 state and local courthouses statewide, prescription lenses included, and anyone wearing a pair has to leave it with a court officer at the door GovTech, New York Will Ban Smart Glasses From All Courthouses. And earlier in 2026, the U.S. Air Force barred smart glasses with photo, video, or AI capability while in uniform, citing the operational security risk of always-on sensors and cloud-connected devices that can capture more than the wearer realizes Military Times, Wearing smart glasses in uniform jeopardizes OPSEC, Air Force says.

Why This Isn't the Old Phone-Camera Debate

Planners have managed camera etiquette for decades because a phone is easy to spot: someone holds it up, points it, and in many cases it makes a shutter sound. Meta-style glasses look like ordinary eyewear, sit on someone's face during a normal conversation, and carry a camera and microphone that can be running without any of the usual tells. Scale matters here too. EssilorLuxottica, the maker of Ray-Ban Meta glasses, sold more than seven million units in 2025, roughly tripling its 2023 and 2024 combined volume CNBC, Ray-Ban maker EssilorLuxottica says it more than tripled Meta AI glasses sales in 2025. Meta has reportedly discussed roughly doubling manufacturing capacity to push annual output toward 20 million units by the end of 2026, with some reporting putting a ceiling as high as 30 million if demand holds Bloomberg, Ray-Ban Meta Glasses May See Output Double as Demand Surges. That is a lot of eyewear walking into hosted-buyer meetings, closed-door briefings, and trade show booths where no one in the room necessarily knows whether the person across the table is recording.

The Gap Sitting in Most Event Contracts

Confidentiality clauses, sponsor NDAs, and standard photo and video consent language were all written with a specific device in mind: something a person visibly holds up and points. None of that language anticipates a pair of glasses. Reporting on how organizers are responding shows three approaches so far, often layered together: opt-in photo and video consent checkboxes at registration, contract clauses that prohibit the devices in specific rooms or sessions, and outright bans on the DEF CON model Meetings Skift, Should Meta Glasses Be Banned at Meetings?. What the four institutions above have in common is that each decided its policy before the doors opened, rather than improvising an answer at a badge scanner when something looked off about a guest's glasses.

What This Means for Your Next Event

An outright ban is not the right call for every event, especially one built around casual networking rather than closed-door content. But leaving the question unanswered is no longer a neutral choice. Hosted-buyer meetings, board sessions, supplier negotiations, and any event with talent or VIP guests carry the most obvious exposure, and their organizers are also the ones most able to actually enforce a device policy at the door. A line in the code of conduct, signage at registration, and matching language in speaker and sponsor agreements cover most of the gap without needing DEF CON's blanket approach. What no organizer running an event this year should assume is that nobody on the floor is wearing a pair. The sales figures say otherwise.

Key Takeaways

• DEF CON 34 (August 6 to 9, 2026, Las Vegas) banned Meta-style recording glasses outright, with no exception for prescription lenses, and treats covert recording as a Code of Conduct violation.
• Three other institutions independently banned the same category of device within roughly the same seven-month window: UK Comic Con organizer Monopoly Events, the New York state court system (all 1,240 courthouses, effective July 20, 2026), and the U.S. Air Force (while in uniform, earlier in 2026).
• EssilorLuxottica sold more than seven million Ray-Ban Meta-style glasses in 2025, roughly tripling year over year, and Meta has reportedly discussed production targets as high as 20 to 30 million units annually by the end of 2026.
• Standard event confidentiality clauses and photo and video consent language were written for smartphones and press badges, not for eyewear with an always-on camera and microphone.
• Most conferences don't need a DEF CON-style outright ban, but hosted-buyer meetings, closed sessions, and events with VIP guests should decide a device policy, in writing, before the show opens rather than at the registration desk.
