Due to technical advances, there has been an enormous improvement of electronic vision aids in recent years. New developments are especially small portable devices which can be easily carried. The majority of electronic vision aids serve as a reading aid. Electronic magnifiers are a portable alternative to conventional screen readers. In addition, there are mobile reading devices and special computer tools. Color recognition devices and barcode scanners are helpful in everyday life. Ultrasonic orientation systems enable the recognition of obstacles also at head height. Mechanisms incorporated in shoes even comprise a navigation system. A brand new development is OrCam (OrCam Technologies Ltd., Israel), a small, inconspicuous camera system which is attached to the spectacles. It transmits vision information as a text. Smart phones and tablet personal computers have meanwhile been developed to such an extent that they replace more expensive special vision aids. Due to the immense technical progress, electronic vision aids provide visually impaired people with many elegant functions and new possibilities for ophthalmological rehabilitation. Besides the technical, mobile and financial aspects, the social acceptance of the devices, which should be as unobtrusive as possible, plays an essential role.
由于技术进步，近年来电子视觉辅助设备有了巨大改进。新的发展尤其体现在小型便携式设备上，这些设备便于携带。大多数电子视觉辅助设备用作阅读辅助工具。电子放大镜是传统屏幕阅读器的一种便携式替代品。此外，还有移动阅读设备和特殊的计算机工具。颜色识别设备和条形码扫描仪在日常生活中很有帮助。超声波定位系统甚至能够识别头部高度的障碍物。鞋中内置的装置甚至包含导航系统。一项全新的发展成果是OrCam（以色列OrCam技术有限公司），这是一种附着在眼镜上的小型、不显眼的摄像系统。它将视觉信息以文本形式传输。与此同时，智能手机和平板电脑已发展到在一定程度上可以取代更昂贵的特殊视觉辅助设备。由于巨大的技术进步，电子视觉辅助设备为视力受损者提供了许多出色的功能以及眼科康复的新可能性。除了技术、移动性和经济方面，这些设备应尽可能不引人注目，其社会接受度也起着至关重要的作用。
