The '''Epson Moverio BT-300''' is a developer [[augmented reality]] [[smart glasses]] developed by [[Epson]], released in 2016. The world's lightest binocular, see-through smart glasses powered by Si-OLED technology at release, the BT-300 features a 1280x720 HD display with 100,000:1 contrast ratio, 23° field of view, Intel Atom X5 quad-core processor, Android 5.1 operating system, 5 MP camera with 1080p video, and weighs just 69g. With 6 hours of battery life and support for 3D content, the BT-300 targets AR developers, drone FPV pilots, and enterprise applications.
The '''Epson Moverio BT-300''' is a binocular [[smart glasses]] device developed by [[Epson]], announced at Mobile World Congress in February 2016 and released in October 2016 at a price of $699 for the AR/Developer Edition. The BT-300 represented a significant advancement over its BT-200 predecessor, introducing Epson's breakthrough Silicon-OLED (Si-OLED) display technology that enabled 100,000:1 contrast ratio and truly transparent augmented reality—when no content is displayed, the lenses appear nearly clear. Weighing just 69 grams for the glasses portion (the world's lightest binocular see-through smart glasses at launch), the BT-300 featured 720p HD resolution across both lenses, an Intel Atom X5 processor running Android 5.1, and a connected controller unit handling processing and battery. Popular applications included drone FPV piloting (with a dedicated Drone Edition), museum exhibits, entertainment venues, and industrial information display.

== History and Development ==


Epson announced the Moverio BT-300 in 2016 as the successor to the BT-200, introducing groundbreaking Si-OLED display technology for transparent smart glasses. More than 20% lighter than its predecessor, the BT-300 became popular for drone first-person view (FPV) applications and AR development. A specialized Drone FPV Edition was also released. The BT-300 was succeeded by the Moverio BT-40 series with USB-C connectivity.<ref name="epson">{{cite web |url=https://news.epson.com/news/epson-announces-the-moverioR-bt-300-the-worlds-lightest-binocular-see-through-smart-glasses-with-breakthrough-display-technology |title=Epson Announces Moverio BT-300 |publisher=Epson |access-date=2025-01-07}}</ref>
