How can you tell if someone's glasses are recording you?

Where the lens is on a pair of glasses

On spy glasses, the lens is most often in the bridge between the two lenses, sometimes disguised as a decorative rivet or a dark dot. The other common spot is a hinge corner, where the arm meets the front, often with a matching fake dot on the opposite side so the frame looks symmetrical.

On smart glasses, the camera is usually a small round window at one outer corner of the front frame. A second small light near it is typically the recording indicator.

All camera glasses need a battery and a circuit board, so the arms are thicker than on normal frames, especially toward the ears. A charging port or contact pads are often on the inside of an arm or the underside of the frame.

What you can notice without touching anything

• Unusually thick arms. Normal frames taper to thin temples. Camera frames stay chunky all the way back.
• A dot in the bridge or corners that glints. When light hits a lens, it reflects as a small, sharp point, unlike the dull shine of plastic.
• Pointing behavior. Someone recording with glasses tends to face things squarely and hold still, because head movement ruins the footage.
• Touching the arm. Many models start and stop recording with a tap or press on the temple.
• Glasses worn where they make no sense. Dark frames indoors at night, or glasses on someone who takes them off to read, can be a hint.
• A covered or taped corner. Smart glasses often have a light that shows recording. Tape, paint or a sticker over that spot is a reason for concern, because the light can be covered.

What a phone scan can and cannot do here

Be realistic. A room scan is built for fixed objects. Camera glasses move with a person, rarely join the local Wi-Fi, and record to their own storage or to the wearer's phone.

The Bluetooth scan is the Candor check most likely to help. Many smart glasses stay connected to the wearer's phone over Bluetooth Low Energy, and some advertise a name that looks like a camera or wearable. Candor also flags close devices with no name, and signal strength gives a rough sense of distance. That can tell you a device is near, but not whose it is. Spy glasses often have no Bluetooth at all.

The lens finder can show a lens glint if you are facing the person with your phone light on, but pointing a flashlight at someone's face is not a practical or polite test. The Wi-Fi scan only helps if the glasses have joined the same network as you, which is uncommon. The magnetic sensor is not useful on a person.

Your options if you think you are being recorded

You cannot search another person, and trying can put you at risk. The practical choices are simple. You can ask directly whether the glasses are recording. You can leave or move out of view. You can tell staff, security, a manager or the event organizer, who can ask the person to stop or leave.

In workplaces, gyms and similar spaces, recording is often against the rules even where it is legal. Recording in private spaces such as bathrooms or changing areas is a crime in many places. If you believe that happened, note the time, place and a description of the person, and contact police. See how to check a changing room for hidden cameras for fixed devices in those spaces.

Steps to take if you suspect camera glasses

1. Look at the frame from a normal distanceCheck the bridge and the outer corners for a small dark dot or window, and notice whether the arms are much thicker than normal frames.
2. Watch for a light or a covered lightSee whether a small light near a front corner is on, or whether that spot has been covered with tape or a sticker.
3. Notice how the glasses are usedPay attention to repeated taps on the arm and to the person holding their head still while facing you or a specific area.
4. Run a Bluetooth scanOpen Candor's Bluetooth scan and look for a close device with a camera-style or wearable name, or a strong unnamed device. Treat it as a hint, not proof.
5. Ask, move, or tell someone in chargeIf it feels safe, ask whether they are recording. Otherwise move away and tell staff, security or management.
6. Write down what you sawRecord the time, place and a description. Contact police if you believe you were recorded in a private space.
