Smart Glasses Privacy Risks: 5 Easy Steps to Protect Your Data in 2026

Smart glasses are the next big thing: they snap pics, give directions and answer questions about what you see. But what if they’re also watching YOU?

You’re at a café, sipping your latte, when someone walks in wearing sleek smart glasses. They glance at you, and their glasses pull up your name, phone number and home address. Creepy? Absolutely. And it isn't science fiction: in 2024, two Harvard students showed it could be done by pairing Ray-Ban Meta glasses with a face search engine (404 Media).

Smart glasses are going mainstream. Meta says millions of people now use its AI glasses every day (Meta), and in July 2026 TechCrunch reported that Even Realities, which makes glasses with no camera, had reached a $1 billion valuation. The problem? Most users don't realize how much personal data these glasses collect, or how it can be misused.

This guide breaks down the privacy risks of smart glasses in plain terms and shares easy steps to protect yourself. Whether you’re considering buying a pair or just want to stay safe around others who wear them, here’s what you need to know.

What Data Do Smart Glasses Collect? (And Why It Matters)

Smart glasses aren’t just fancy sunglasses—they’re mini computers strapped to your face. And like any computer, they collect data. A lot of it.

Why they're different from a phone camera

You can see when someone holds up a phone to take a picture. Glasses are harder to spot: the camera sits in the frame, and the wearer can take a photo with a voice command, without lifting a hand (Meta). Meta's glasses blink a small white light on the front while they capture photos or video (Meta), but people nearby may not notice it.

Facial recognition: The "who’s that?" problem

Imagine walking into a room and your glasses instantly tell you the names of everyone there, even strangers. That's facial recognition in action. Some smart glasses can scan faces in a crowd once they are connected to face search tools, as the Harvard demo showed, and if you're the one being scanned, here's how to stop Meta glasses from scanning your face.

Meta had not switched this on for its own glasses as of mid-2026. In June 2026, WIRED found code for a face recognition feature called NameTag inside the Meta AI app, and Meta said nothing had shipped to consumers and no final decision had been made (WIRED). Here's the creepy part: the people being identified might not know it's happening, and they never agreed to it.

Location tracking: A map of your life

Smart glasses and their companion apps can use your phone's location for features like directions. If the app is allowed to use your location all the time, it can log where you go: when you leave home, where you work, and even which coffee shop you visit on weekends.

Location data like this can be used to target you with ads, or leaked in a data breach.

Audio recording: Eavesdropping made easy

Glasses with a voice assistant listen for a wake word, like "Hey Meta." Meta's voice privacy notice says it processes what you say after the wake word, including accidental activations and any background sound while the assistant is listening, and keeps stored voice data for up to a year (Meta). A setting called Respond without "Hey Meta" is also on by default, and it keeps the microphone on for a little while after each request (Meta help).

This isn’t just about accidental recordings—it’s about who might be listening. If your glasses are hacked, someone could eavesdrop on your conversations in real time.

Biometric data: Your eyes don’t lie

Eye-tracking tech in smart glasses can reveal a lot about you. For example, it can detect fatigue, stress, or even predict your emotions. Companies could use this data to target ads, like showing you a coupon for meditation apps if you seem stressed. It’s like having a therapist, marketer, and stalker all rolled into one device.

The data trail: glasses, phone, cloud

A photo doesn't stay in the frame. Meta says photos and videos are stored on the glasses until you import them to your phone, where they're saved to your phone's gallery like any other picture (Meta). If your gallery backs up to the cloud, they go there too. Anything you ask Meta AI about is different: visual content shared with the assistant can be used to improve Meta's products and can be reviewed by people (Tom's Guide).

Every file also carries details such as when it was taken and on which device. Put together, that trail says more about you, and about the people in your photos, than the picture alone.

5 Privacy Risks of Smart Glasses (And How to Spot Them)

Photo by cottonbro studio on Pexels

Smart glasses are convenient, but they come with serious privacy risks. Here’s what to watch out for—and how to protect yourself.

1. Unwanted facial recognition

Risk: Strangers’ faces could be scanned and stored without their consent. This data could be used for anything from targeted ads to identity theft.

How to spot it: Check whether your glasses, or any app connected to them, offers to identify people. Meta's glasses did not offer this as of mid-2026 (WIRED).

Fix: Don't connect apps that identify faces, and switch face recognition off if your glasses ever add it. The next section covers what you can switch off today.

2. Always-on location tracking

Risk: Your daily movements could be sold to advertisers or leaked in a data breach. Imagine someone knowing exactly when you leave for work or visit the doctor.

How to spot it: If your glasses' app asks for "background location access," it can read your location even when you're not using it.

Fix: Limit location access to "while using the app" only. This way, your glasses only track you when you’re actively using them.

3. Eavesdropping on conversations

Risk: Microphones can pick up private chats, even if you’re not recording. This data could be stored, analyzed, or even hacked.

How to spot it: Check whether your glasses listen for a wake word, like "Hey Meta," and whether the mic stays open after you ask something. Listening for a wake word is not the same as recording everything, but what you say after it can be stored (Meta).

Fix: Turn off the wake word if you don't use it, and switch the glasses off when you take them off. The steps are in the next section.

4. Data sharing with third parties

Risk: Companies might sell your data to advertisers, insurers, or other third parties. This could include everything from your location history to your biometric data.

How to spot it: Read the privacy policy (yes, really!) for phrases like "share with partners" or "anonymized data." If it’s vague, assume your data is being shared.

Fix: Turn off any data sharing or storage your app lets you turn off. Meta's voice privacy notice, for example, says you can change its default storage settings in the app (Meta).

5. Hacking and data breaches

Risk: Weak security could let hackers access your glasses’ camera or mic. This could lead to anything from blackmail to identity theft.

How to spot it: Watch the news for your brand. In early 2026, for example, two Swedish newspapers reported that contractors in Kenya labeling data for Meta's AI were seeing private footage from the glasses, including people undressing (Tom's Guide).

Fix: Enable two-factor authentication (2FA) and keep your software updated. This adds an extra layer of security to your account.

How to Lock Down Your Smart Glasses: Settings to Change Now

You don’t need to be a tech expert to protect your privacy. Here’s how to tweak your smart glasses’ settings for maximum security. The steps use Meta's glasses as the main example, because Meta has the vast majority of smart glasses shipments (The Next Web). The companion app is now called Meta AI (it used to be Meta View), and menus can move with app updates, so look for the same names if yours look different (Meta help).

Disable facial recognition

Ray-Ban Meta and Oakley Meta: There was no face recognition setting to switch off as of mid-2026, because Meta had not released the feature (WIRED). If it arrives, check whether it is on by default and turn it off if you don't want it.

Even Realities: Its glasses have no camera, so there is nothing to recognize faces with (TechCrunch).

Any brand: Don't link apps or services that identify people from photos.

Limit location tracking

Location permission lives in your phone's settings, not only in the glasses app:

iPhone:

1. Open Settings > Privacy & Security > Location Services.
2. Tap your glasses' app.
3. Choose While Using the App or Never (Apple).

Android:

1. Open Settings > Apps and pick your glasses' app.
2. Tap Permissions > Location.
3. Choose Allow only while using the app or Don't allow (Google).

That stops the app from reading your location in the background. While you're there, check which apps can use your Camera and Microphone (on iPhone, under Settings > Privacy & Security) and turn off any that don't need them (Apple).

Turn off always-listening mics

Ray-Ban Meta and Oakley Meta:

1. In the Meta AI app, tap Glasses in the top right, then Device settings.
2. Tap your glasses, then Meta AI, then "Hey Meta" preferences.
3. Turn off Respond without "Hey Meta". It is on by default and keeps the microphone on for a little while after each request (Meta help).

If you don't use the voice assistant at all, turn off "Hey Meta" too. Meta's privacy policy says AI camera use stays enabled unless "Hey Meta" is off (The Verge), and you can still take photos and calls without it (Tom's Guide).

Any pair: Switch the glasses off when you take them off. On Ray-Ban Meta and Oakley Meta HSTN, the power switch is on the inside of the left arm, near the hinge; slide it toward the back of the glasses (Meta help).

Opt out of data sharing

Ray-Ban Meta and Oakley Meta:

• Voice: Meta's voice privacy notice (US version, effective July 22, 2025) says transcripts are stored by default, that you can change the storage settings in the app at any time, and that with storage off, recordings are deleted right after processing and are not reviewed by people (Meta). The notice differs by country, so check the settings in your own app.
• Photos and videos: Keep cloud processing off if you don't need it, so your media stays on your device instead of going to Meta's servers (Tom's Guide).

All brands: Look in the app's privacy settings for anything about sharing data or improving products, and switch off what you didn't choose.

iPhone users: If your glasses' photos end up in iCloud Photos, turning on Advanced Data Protection (Settings > your name > iCloud > Advanced Data Protection) end-to-end encrypts them, so not even Apple can read them. You'll need to set up a recovery contact or recovery key first (Apple).

Delete old recordings regularly

Clear out photos, videos and voice history you no longer need. The less that's stored, the less there is to leak if your account is ever compromised. In the Meta AI app, you can view and delete your stored voice interactions (Meta).

Enable two-factor authentication (2FA)

Your glasses are tied to an account, so protect it. Turn on two-factor authentication for the account your glasses' app signs in with, and use an authenticator app if it's offered. This adds an extra layer of security to your account, making it harder for hackers to break in.

Know the recording rules where you wear them

Owning the camera doesn't mean you can point it anywhere:

• Audio has stricter rules. Federal law lets you record a conversation you're part of, but about 11 states, including California, Florida, Illinois and Washington, require everyone's consent to record a private conversation (Reporters Committee for Freedom of the Press).
• Private places are off-limits. Every state has laws against certain uses of hidden cameras in private places (RCFP). Leave the camera off in bathrooms, changing rooms, doctor's appointments and private meetings.
• Some places ban the glasses outright. New York's state courts banned glasses with cameras or microphones, prescription pairs included, from July 20, 2026 (GovTech), and the DEF CON conference banned recording glasses in 2026 (Cybernews).
• Ask first in semi-private spaces like a gym or a classroom. A quick "These glasses have a camera, is that okay?" goes a long way.

Extra Protection: How a VPN Can Help (And How to Set It Up)

Photo by Ketut Subiyanto on Pexels

A VPN (Virtual Private Network) encrypts your internet traffic, hiding your IP address and activity from the network you're on. It’s like sending your data through a secret tunnel instead of a public highway.

Why use a VPN with smart glasses?

Many smart glasses lean on the companion app on your phone, so your phone's connection matters. A VPN on the phone encrypts what it sends, which helps most on public Wi-Fi, where other people on the network could otherwise see more of your traffic.

How to set it up

1. Install a VPN on the phone your glasses pair with. (If you’re comparing providers, check out our GhostShield vs NordVPN comparison.)
2. Keep it connected while the app syncs, especially on public Wi-Fi. A VPN on your phone covers what the phone sends. It doesn't cover anything the glasses send over a different connection.
3. Use split tunneling (if available). Some VPNs let you choose which apps use the VPN, so you can make sure the glasses' app always goes through it.

Limitations of a VPN

A VPN won’t stop facial recognition or mic recording, and it doesn't stop the maker of your glasses from receiving what you share with it. It hides your traffic from the network you're on and swaps your IP address for the server's, but it doesn't hide the GPS location your apps can read. Think of it as one piece of your privacy toolkit.

If You're Around Someone Wearing Smart Glasses

You can't switch off someone else's glasses, but you can lower your exposure:

• Watch for the light. Meta's glasses blink a white light on the front while they capture photos or video (Meta). It isn't a guarantee, so treat a camera pointed at you as a camera.
• Step out of frame, or ask. Moving seats is often enough, and a polite "Are those recording?" is a fair question.
• Save sensitive talk for private places. In a crowded cafe or on a train, assume a conversation could be overheard or recorded.
• Report footage that gets posted. Most platforms have a privacy reporting process for videos of you shared without your consent.

For the full picture, including where the glasses are banned and how to get footage taken down, see our guide on how to protect yourself from Meta glasses.

Smart Glasses Privacy: What’s Next in 2026?

Smart glasses are still new, but they’re evolving fast. Here’s what to expect in the coming months—and how to stay ahead of the curve.

Stricter laws

Rules are slowly catching up. In the EU, the AI Act has banned untargeted scraping of images from the internet or CCTV to build face recognition databases since February 2025 (European Commission). Venues are acting too, from New York's courthouses to DEF CON, as covered above. Expect more rules on where camera glasses can go.

Privacy-focused brands

Not all smart glasses are created equal. Some makers leave the camera out entirely: Even Realities' G2, for example, shows information on a display built into the frames and has no camera (TechCrunch). If privacy is your top priority, a pair without a camera removes the biggest risk.

What you can do

• Support brands with transparent privacy policies. Look for companies that are upfront about what data they collect and how they use it.
• Advocate for "privacy by design." Push for features like physical camera/mic shutters, which let you physically block the lenses when not in use.

Key Takeaways: 5 Easy Steps to Protect Yourself

Smart glasses are here to stay, but that doesn’t mean you have to sacrifice your privacy. Here’s what you can do today to stay safe:

• Keep face recognition off. Meta had not released it as of mid-2026; if your glasses ever offer it, turn it off, and don't link apps that identify people.
• Limit location tracking to "while using the app" in your phone's settings to avoid being followed.
• Turn off the extra listening. Switch off Respond without "Hey Meta" (or "Hey Meta" itself if you don't use it), and power the glasses off when you take them off.
• Use a VPN on the paired phone to encrypt what it sends on public Wi-Fi and hide your IP address. (GhostShield is one option: it runs on WireGuard, keeps no logs and has apps for iPhone and Android. Check out our pricing to learn more.)
• Update your software regularly to patch security holes.
