Preorders opened Thursday for Google and Samsung's AI smart glasses, with Warby Parker models starting at $395 — a price point that puts a camera, an assistant and open-ear speakers on the face of ordinary consumers. Gentle Monster frames start higher, at $449 and run to $489. Both collections go on sale December 10 in the U.S.; the Gentle Monster line also launches in South Korea the same day.

Samsung engineered the hardware. Google developed the product alongside it and supplies Gemini, its AI assistant, built into every frame. The lineup spans 30 designs across six Gentle Monster frame styles and three Warby Parker styles.

What do the glasses actually do?

The numbers first. Each pair weighs about 41 grams (roughly 1.4 ounces) and carries a battery rated for up to nine hours. The charging case recharges the frames up to seven times, extending use across a week for moderate wearers. A 12-megapixel camera sits in the frame alongside open-ear speakers, and the glasses pair with Pixel phones, Samsung phones and iPhones — a notable broadening beyond Google's own devices.

Users summon the assistant by saying "Hey Gemini" or tapping the frames. Google says Gemini can:

• add items to a grocery list
• check a user's Google Calendar when they look at an event poster
• handle calls and messages hands-free
• deliver turn-by-turn directions through Google Maps
• translate speech in real time in more than 70 languages

These are convenience claims from the vendor, not independent test results. Whether calendar-from-a-poster works reliably outside demonstration conditions remains unverified until reviewers get hardware in hand.

What about bystanders and privacy?

This is where the companies anticipate the hardest questions — and where their language deserves scrutiny. Google said camera visuals from Gemini never enter Gemini History, the user's conversation log, and stay out of AI model training and ad targeting. That is a promise about Google's data pipelines, and it rests entirely on the company's own enforcement.

Two design choices address bystanders. The glasses redact bystanders' faces before Gemini processes images, and an indicator light activates whenever the user captures a picture or clip. The glasses are also built to halt recording if anyone blocks or disables that light — a hardware safeguard, though Google did not detail how tamper detection performs in practice.

Samsung set its own boundary: the glasses target users aged 18 and over, with age verification required for activation. How that verification works, and whether it can be circumvented, was not specified.

"As glasses become more capable, our focus is on creating helpful experiences that make both wearers and bystanders feel protected," Shahram Izadi, Google's vice president and general manager of its XR (extended reality) unit, wrote in a separate post on Thursday, according to Bloomberg. The phrasing is telling — "feel protected" is a perception claim, not a guarantee, and the gap between the two is where smart-glasses controversies have historically lived.

What does this change for buyers?

Preorders are live online and in stores at Gentle Monster and Warby Parker. Customers can sign up for a guided demo at more than 360 Warby Parker locations, and hands-on demos will run at select Google Store locations. For a market that has watched smart glasses stumble on price, battery life and social acceptance, the offering answers the first two objections: $395 undercuts most flagship wearables, and nine hours plus a seven-recharge case covers a full day.

The third objection — whether people will accept being filmed by strangers — is answered only by design mitigations and policy pledges. December 10 will show whether consumers accept that bargain.
