A new reading aid (called "kraspegig") for patients with macular blindness is described. It is based on the principle that, in peripheral vision, our attention is strongly drawn to moving objects. Accordingly, it sets the reading matter moving with respect to the patient's retina. Its essential part is a patterned mask into which is cut a window through which a few words of text can be seen. As the mask is slid along, the patient follows it with his eyes, so that the text lags behind. A magnifier is part of the device.
本文介绍了一种用于黄斑失明患者的新型阅读辅助工具(称为“kraspegig”)。它基于这样一个原理:在周边视觉中,我们的注意力会被移动物体强烈吸引。因此,它使阅读材料相对于患者的视网膜移动。其核心部分是一个有图案的面罩,上面开了一个窗口,透过窗口可以看到几个文字。当面罩滑动时,患者用眼睛跟随它,这样文字就会落在后面。该设备还包括一个放大镜。
