Smart glasses are wearable devices that look like regular glasses but come with advanced technology. They can display information directly in your line of sight, allowing you to see notifications, maps, or even videos without needing to look at your phone. Some models also have built-in cameras, enabling you to take photos or record videos hands-free. These glasses often connect to your smartphone via Bluetooth, making it easy to receive calls or messages. With features like voice commands and augmented reality, smart glasses are becoming popular among tech enthusiasts and professionals alike, offering a new way to interact with the digital world while keeping your hands free.
