The Dream Glass 4K is a portable augmented reality display glasses device developed by DreamWorld USA Inc., launched via Indiegogo in 2019 and shipping in 2020 at approximately $500. Marketed as "the world's first portable and private AR HMD," the Dream Glass 4K features a 90° field of view (significantly wider than many AR headsets) with dual 1920 × 1080 displays providing a 4K-equivalent viewing experience that projects a virtual 200-inch screen at 3 meters distance. The two-part system consists of lightweight AR glasses (185g) connected via cable to a control box containing the battery, processor, and 10 interface buttons—enabling approximately 5 hours of usage and universal compatibility with HDMI or USB-C video sources including smartphones, game consoles (PS4, PS5, Xbox, Nintendo Switch), laptops, and PCs. Supporting both 2D and 3D content with an 18:9 aspect ratio, the Dream Glass 4K targets entertainment, gaming, and portable cinema use cases while maintaining compatibility with prescription glasses. DreamWorld USA, founded in Silicon Valley in 2016 by AR enthusiasts experienced in optics and computer vision, previously shipped thousands of units of the Gen 1 Dream Glass Air headset.
