Introduction to smart glasses
In recent years, smart glasses have gone from being a science fiction fantasy to a technological reality with practical applications in everyday life. Major companies such as Google, Meta, Xiaomi, and Huawei are investing in the development of this innovative technology that promises to transform the way we interact with the digital world.
But what are smart glasses really, what features do they offer today, and how could they change our future? Let's find out.
What are smart glasses?
Smart glasses are wearable devices that combine the functions of conventional glasses with advanced technology, allowing digital information to be integrated directly into the user's field of vision. Their goal is to offer an augmented reality experience, connectivity, and assistance without the need to constantly look at a smartphone.
In short, they seek to merge the best of natural vision with the best of the digital world.
Brief history and evolution of smart glasses
The concept isn't new. In 2013, Google introduced Google Glass , one of the first commercial attempts at smart glasses. Although it wasn't as successful as expected due to technical limitations and privacy concerns, it paved the way for new innovations.
Today, companies like Meta with its Ray-Ban Stories , Xiaomi Smart Glasses , and Nreal Air have refined the idea, incorporating lighter displays, discreet cameras, and improved interaction systems. The future looks increasingly promising.
Main features of smart glasses
Modern smart glasses include a variety of features that make them attractive to both everyday users and professionals.
Augmented reality (AR) displays
They allow digital information to be projected onto the physical world: from maps and notifications to interactive 3D models.
Connectivity with smartphones and IoT devices
They sync with smartphones, watches, and other connected devices, allowing you to control music, calls, and messages hands-free.
Voice assistants and gesture control
Voice control, and in some cases, gesture control, makes it easy to interact without the need for buttons.
Integrated cameras and real-time recording
They incorporate discreet cameras to capture photos and videos from the user's perspective, a useful feature in professional fields such as medicine or journalism.
Practical features of smart glasses today
Beyond innovation, smart glasses already offer useful applications:
Real-time navigation and maps
They facilitate mobility by displaying directions on the screen without taking your eyes off the road.
Instant translation and automatic subtitles
Some models allow you to translate conversations in real time, displaying subtitles on the glass.
Notifications and productivity at work
Receiving messages, emails, or reminders directly on your lens improves productivity without interrupting your workflow.
Entertainment and immersive experiences
From watching movies to playing with augmented reality elements, smart glasses expand your entertainment possibilities.
Smart glasses in different sectors
Medicine and health
In the medical field, smart glasses are revolutionizing the way professionals work. Surgeons use smart glasses to view clinical data in real time during an operation without taking their eyes off the patient. They are also being used in telemedicine, allowing doctors in different locations to collaborate remotely with first-person transmission. 
Education and vocational training
Education is another sector that will benefit. Teachers can use augmented reality to enrich their classes, displaying 3D models of anatomy, history, or engineering directly in front of students. In vocational training, smart glasses facilitate more realistic and practical training.
Industry, logistics and maintenance
In factories, warehouses, and workshops, smart glasses help workers follow step-by-step instructions without having to consult manuals. They also allow technicians to view drawings or diagnostics while repairing machinery.
Fashion and lifestyle
Beyond functionality, these devices are evolving to be elegant and discreet. Brands like Ray-Ban have collaborated with tech companies to merge fashion and technology, making wearing smart glasses not only useful but also attractive.
