What if your glasses replaced your smartphone?
The smartphone has dominated our daily lives for nearly 20 years. But a new generation of devices is ready to take over—not in your pocket, but on your nose. Smart glasses are evolving fast and could soon become your primary digital tool.
Why change?
Smartphones force us to disconnect from the real world: head down, fingers busy, attention fragmented. Smart glasses, on the other hand, integrate into your natural field of view. They display real-time information without taking you away from people, the street, or your surroundings. Less interruption. More context.
Today’s features
Current models like Ray-Ban Meta, XREAL Air, or the latest Apple Vision Pro in mixed reality format already offer a wide range of functions:
- Hands-free calls thanks to directional microphones
- Instant translation during conversations in foreign languages
- Messages, reminders, and weather displayed in a corner of your vision
- Voice or gesture-controlled web browsing
- Discreet photo or video capture via button or voice command
- Object or face recognition assistance, within strict privacy limits
How AI makes the difference
The real transformation comes not from the display, but from the artificial intelligence behind it. AI can:
- Remind you of someone’s name when you meet them: “This is Sophie, met at the tech fair in April”
- Translate a menu or sign in real time, overlaid on reality
- Guide you through an unfamiliar street with arrows projected on the ground ahead
- Alert you if you leave an object behind, using a connected sensor
Challenges to overcome
Not everything is perfect yet:
- Battery life: around 4 to 6 hours of active use
- Design: some glasses are still slightly heavier or thicker than standard models
- Privacy: concerns about constant surveillance are real. Manufacturers address this with on-device data processing and visible camera indicators
- Price: from 300 to 3000 euros depending on features
The future? A natural interface
Experts speak of a "post-smartphone era". The idea is an interface that follows your gaze, understands context, and responds seamlessly. Tomorrow, glancing at a product in a store could instantly show its price, availability, or reviews. Looking at a burnt-out lightbulb might prompt your assistant to suggest ordering a replacement.
Toward invisible technology
The next leap won't be a new screen, but a smooth integration of technology into human perception. Smart glasses are more than a gadget. They could become an extension of your senses—discreet, useful, and always with you.
The future might already be wearing glasses.
