RayNeo has announced the upcoming RayNeo iO+, its fourth-generation AI glasses, featuring a dual-eye full-color MicroLED light-waveguide display and a more compact light engine. According to the company, the glasses use a rounded frame with vintage tortoiseshell elements and gold accents. Their temples are similar in size to those of the preceding iO, and RayNeo says the new waveguide reduces rainbow artifacts, light leakage and lens reflections. Detailed specifications, feature configurations and the official release date have not yet been disclosed.
