    • A device that enlarges text and images to enable a low vision person to see the text and images includes a hollow structure including a top housing and a bottom housing that are connected to one another. A camera aperture is formed in the bottom housing and a transparent light guide lens is disposed in closing relation to the camera aperture so that all light entering the camera aperture must first pass through the light guide lens. A cavity formed in the light guide lens is bounded by walls that are positioned at a critical angle. Light-emitting diodes are positioned at critical locations about the periphery of the light guide lens to illuminate the object being viewed.
    • 放大文本和图像以使低视力人士看到文本和图像的装置包括中空结构,其包括彼此连接的顶部壳体和底部壳体。 相机孔形成在底部壳体中,并且透明导光透镜以相对于相机孔的关系设置,使得进入相机孔的所有光必须首先通过光导透镜。 形成在导光透镜中的空腔被定位在临界角的壁限定。 发光二极管位于围绕光导透镜的周边的关键位置,以照亮被观察的物体。
