A wave of lightweight eyewear now packs cameras, speakers, and AI assistants into ordinary-looking frames, letting wearers ask questions about what they see.
Smart glasses embed miniature cameras, microphones, speakers, and often an AI assistant into a near-ordinary-looking frame, letting wearers capture photos or ask spoken questions hands-free. This works because manufacturers shrank cameras, batteries, and processors small enough to fit unnoticed in the frame.
Reading bifocals are just glasses with two lens prescriptions, a purely optical aid with no electronics. Window tint film blocks light for privacy, also unrelated to computing or communication.
Many newer smart glasses skip any display screen entirely, relying on voice and audio, a design choice that keeps them lighter and more socially normal-looking than earlier heads-up-display versions.
