The fundamental difference between Virtual Reality (VR) and Augmented Reality (AR) lies in their relationship with the real world.

VR is immersive; it replaces your physical environment entirely with a computer-generated simulation. When you put on a VR headset, you are transported to a digital world — a game, a training simulation, or a virtual social space — and are visually disconnected from your actual surroundings.

In contrast, AR is additive; it layers digital information or objects onto your view of the real world. AR allows you to see your physical environment through a lens or screen, with graphics, text, or 3D models superimposed on top of it.

VR headsets typically feature high-resolution screens placed close to the eyes, powered by a connected computer or have their own built-in processor. These headsets use advanced tracking systems — cameras and sensors — to map your movements, allowing you to walk, reach, and interact within the virtual space.

AR hardware exists on a broader spectrum. On one end are dedicated AR headsets used in industrial settings. On the more accessible end are smart glasses. Devices like the Meta Ray-Ban glasses feature cameras, speakers, and a small display for basic notifications, livestreaming, or AI-assisted information like real-time translation. They augment your experience but do not typically support persistent, complex 3D graphics.
