Smart glasses in schools: a guide for teachers

What smart glasses are

"Smart glasses" covers several quite different products:

• Camera AI glasses such as Ray-Ban Meta and Oakley Meta: a camera and microphones in an ordinary-looking frame, with photos and video saved to a paired phone and a voice assistant. Known fact Meta states the current generation has a 12 MP ultra-wide camera that records video up to 3K and a five-microphone array.
• AR display glasses such as Snap's Spectacles and Specs: see-through displays plus cameras used for hand tracking and capture. Known fact Snap states its 5th-generation Spectacles have four cameras.
• Display-only glasses such as the Even Realities G1: a small heads-up display and microphones, with no camera listed by the manufacturer. Inference These can show text (for example, live captions or notes) without any capability to photograph anyone.
• Audio glasses: speakers and microphones only, for calls and music.

The distinction matters in a classroom: the concern in most policies is capturing images and audio of other people, and only some of these products can do that.

Why schools are discussing them

Three properties set camera glasses apart from phones. They are worn rather than held, so capture is hands-free and does not look like using a device. They look like ordinary eyewear, so the usual cue "someone is pointing a phone at me" is absent. And some models pair a camera with an AI assistant that can describe or identify what the wearer sees. Schools already have rules about recording in classrooms, changing rooms and exams; the question is how to apply them when the device is on someone's face.

Sourced facts about common products

The table summarises what each manufacturer states. Each row links to the product's full record, which includes the source pages and the date we read them.

The capture light

Known fact Meta states that each of its AI glasses has a white capture LED that blinks briefly for a photo and continues to blink for as long as video recording is in progress, and that if the glasses detect the LED has been covered or tampered with, the camera is automatically disabled. Known fact Snap states that its Specs have an LED indicator that lights up when recording is taking place. Inference A visible light is therefore the most reliable everyday cue for those products. It is not a guarantee: the light is small, it is designed to be seen from the front, and manufacturer statements describe intended behaviour rather than every possible condition.

Recognising camera glasses by eye

• Temple thickness. Electronics and batteries live in the arms, which are noticeably thicker than on ordinary glasses.
• Camera lens. A small round lens at the outer edge of one lens rim (Ray-Ban Meta, Oakley Meta HSTN) or centrally on the bridge (Oakley Meta Vanguard, per Meta's product imagery).
• An LED opposite the lens. On Meta's designs the capture LED sits at the other outer corner.
• A charging case shaped like a spectacle case but with a charge indicator.
• Voice commands. Camera AI glasses are operated by a wake phrase or a button on the temple.

Display-only glasses such as the Even Realities G1 are designed to look like ordinary eyewear and have no lens on the front; you may notice a faint green glow from inside the lenses in low light.

What a Bluetooth scanner can determine

Smart glasses, like most wireless accessories, use Bluetooth to talk to the wearer's phone. Bluetooth Low Energy devices often announce themselves with short broadcasts that any nearby phone can receive. An app can compare those broadcasts with known identifiers: the Bluetooth SIG publishes which company registered each company identifier and service UUID, and Meta, Snap, Even Realities and Vuzix all hold registrations. Our app does exactly this and shows the evidence for each match.

What it cannot determine

• Whether anyone is recording. Bluetooth broadcasts carry no information about camera or microphone activity. No Bluetooth-based tool can tell you that a photo or video is being taken.
• Who is wearing them. iOS does not expose hardware addresses, and the app deliberately does not track devices across sessions.
• Whether the room is clear. A device that is connected to its owner's phone may broadcast nothing at all, and Apple limits what a backgrounded app can hear. No detection is not evidence of absence.
• Which specific product, until tested. Company identifiers are shared across a manufacturer's products. The app's scoring keeps single-identifier matches at a low level for this reason, and none of the products above has yet been independently tested by us.
• Distance. Signal strength is a coarse proximity hint, not a measurement; see RSSI and distance.

Inference A scanner is best understood as an awareness aid, similar to noticing a phone on a desk: it may prompt a conversation, and it should never be the sole basis for an accusation or a disciplinary decision.

Policy considerations

Points that schools commonly work through. They are offered as prompts, not as recommendations for any particular jurisdiction.

• Treat capability, not form factor. Many existing policies already cover "devices capable of recording". Whether glasses fall under such wording is a question for the school and its advisers.
• Prescription lenses. Camera AI glasses can be fitted with prescription lenses, so a blanket "no glasses" rule is not workable. Policies tend to focus on the camera and microphone rather than the eyewear.
• Sensitive spaces. Changing rooms, toilets, medical rooms and exam halls are typically the priority, and the expectation is usually that any camera-equipped device is removed or stored there.
• Accessibility. Display-only and audio glasses may be used as assistive technology, for example live captions. Policies that distinguish camera-equipped from camera-free products avoid excluding those uses.
• Consent and data. Manufacturers state that captured media is saved to the wearer's phone and may be processed by cloud AI services; how that interacts with student data rules is jurisdiction-specific.
• Communication. Clear signage and a short explanation to students of what the capture light means tend to be more effective than detection technology.

Where this app fits

Smart Glasses Scanner is not released and makes no detection promises today. When it is, it will be a tool that shows what Bluetooth evidence was observed and how sure it is, with all the limits above stated in the app itself. If you would like to be told when it launches, or when hardware test results are published, leave your email below.
