It provides clear image quality while offering unrestricted portability, supporting mobile use in all indoor and outdoor scenarios. The CloverAir low-vision AR glasses use a modular design that separates the computing unit, battery, and display optical module into two independent parts, greatly reducing the weight of the glasses (around 80g) and heat generation

(around 30C), improving comfort for long-term wear. The glasses are creatively equipped with dual cameras. The front main camera captures visual information such as text and objects and processes it through algorithms to achieve image magnification, contrast enhancement, and color optimization. The processed image is then projected onto the glasses'

binocular HD OLED display module. When switched to the close-up camera, users dont need to lower their heads excessively to capture content on a desk, greatly improving the experience of reading and writing on paper at a desk. In addition, CloverAir is equipped with OCR, mobile screen mirroring, external HDMI input, and a variety of other features 2 and interfaces to seamlessly meet the daily needs of visually impaired person.
