Meta Ray-Ban smart glasses have become the world's best-selling AI glasses, with over 7 million units sold in 2025 alone. With the launch of the Meta Wearables Device Access Toolkit, developers can now build apps that tap into the camera, audio, and sensor capabilities of these glasses, opening up a new platform for hands-free, first-person-view experiences.

In this guide, we break down every developer feature available across Gen 1 and Gen 2 hardware, walk through the SDK and API architecture, explore real-world use cases, and show you how Lushbinary can help you build and ship your Meta Ray-Ban app.

1Gen 1 vs Gen 2: Hardware at a Glance

Before diving into the developer toolkit, it's important to understand the hardware differences between the two generations. Both are supported by the Wearables Device Access Toolkit, but Gen 2 brings meaningful upgrades that affect what you can build.

2The Meta Wearables Device Access Toolkit

The Meta Wearables Device Access Toolkit is the official developer platform for building mobile apps that integrate with Meta Ray-Ban smart glasses. Currently in developer preview, it provides access to on-device sensors, enabling you to extend your mobile app's capabilities into the physical world.

The toolkit includes:

• iOS and Android SDKs with pre-built libraries and sample apps
• API documentation covering architecture, endpoints, data structures, and best practices
• Dedicated testing tools and isolated environments for prototyping
• Beta distribution platform via the Wearables Developer Center for sharing prototypes with testers
• Developer community forums for iOS and Android developers

The toolkit entered public developer preview in December 2025. Developers can now download the SDK, build prototypes, and test on their own glasses. Distribution to testers within your organization is supported via the beta testing platform in the Wearables Developer Center. Public publishing remains limited to select partners for now, with broader general availability expected to roll out later in 2026.

3Camera API: First-Person-View Development

The camera is the most powerful developer-facing sensor on the glasses. The SDK gives your mobile app access to the wearer's point-of-view camera, enabling a category of experiences that simply aren't possible with a phone.

📸 What You Can Do

• Capture POV photos and video from the wearer's natural perspective, no hands required
• Stream camera frames to your app for real-time processing (object detection, OCR, scene understanding)
• Trigger captures programmatically based on app logic, voice commands, or contextual events
• Access high-resolution stills (12MP) and video (up to 3K on Gen 2). Note: video streaming to your app via Bluetooth is capped at 720p / 30fps, with automatic resolution reduction when bandwidth is limited

🎯 Developer Use Cases

4Audio API: Microphone & Speaker Access

The glasses feature a 5-microphone array and open-ear speakers, both accessible through the SDK. This opens up voice-driven and audio-aware app experiences.

• Microphone input: capture ambient audio, voice commands, or conversations with noise cancellation
• Speaker output: deliver audio feedback, navigation prompts, or notifications directly to the wearer
• Voice interaction: build voice-first interfaces that feel natural and hands-free
• Audio streaming: pipe audio to your app for real-time transcription, translation, or analysis

// Initialize the wearable connection
val wearableSession = MetaWearables.connect(context)

// Start audio stream from glasses mic
wearableSession.startAudioCapture { audioFrame ->
    // Process audio frames in real-time
    speechRecognizer.processFrame(audioFrame)
}

// Send audio feedback to glasses speakers
wearableSession.playAudio(notificationSound)

5iOS & Android SDKs

Meta provides native SDKs for both iOS and Android, designed to minimize integration friction and get you prototyping quickly.

Both SDKs include pre-built components for common patterns like device discovery, connection management, and sensor data streaming. The sample apps provide working reference implementations you can build on.

import MetaWearablesSDK

// Discover and connect to nearby glasses
let session = try await MetaWearables.connect()

// Request camera access
let cameraStream = try await session.startCamera(
    resolution: .high,
    frameRate: 30
)

// Process frames as they arrive
for await frame in cameraStream {
    let image = frame.cgImage
    // Run your ML model, display preview, etc.
    await processFrame(image)
}

6Developer Center & Testing Tools

The Meta Wearables Developer Center is the central hub for managing your development workflow. Here's what you get:

7Real-World Use Cases & Partner Spotlights

Meta has been working with select early partners who've already built working integrations. Their projects showcase the range of what's possible:

8What's Coming Next for Developers

The toolkit is currently in public developer preview with camera and audio sensor access. Meta has signaled several areas of active and upcoming expansion:

• Meta AI voice command integration: accessing the glasses' built-in AI assistant capabilities isn't part of the current preview, but Meta has confirmed it's a key area they're exploring for future updates
• General availability publishing: public app distribution is currently limited to select partners. Meta is expected to open broader publishing access later in 2026, so now is the time to build and have your app ready
• New device support: Ray-Ban Meta and Oakley Meta HSTN are currently supported, with Oakley Meta Vanguard and the Meta Ray-Ban Display (with HUD) coming soon
• Facial recognition ("Name Tag"): Meta is actively developing a facial recognition feature for 2026 that could enable meeting recall, friend recognition, and accessibility use cases
• Additional sensor access: as the hardware evolves (Gen 3 is rumored to include a display), expect new APIs for additional sensors and capabilities
