eSight Companion 对比 Case For Vision 的使用情况和统计数据

The application is explicitly designed for use with an iPhone’s Case For Vision optical protective case for people who are visually impaired or experience age-related vision loss. An iPhone’s Case For Vision case is sold separately and can be purchased at www.caseforvision.com. Two functions are Magnifier for local under an iPhone camera and Telescope for remote object magnification. View, zoom in, and pan live magnified images on the iPhone screen instead of moving a physical object under the camera. Freeze, save, and share pictures or video recordings with friends and family. Scroll through three contrast options for better viewing.
