Orientation and mobility for persons with low vision should not be a mere extension of programs for the totally blind. Since seeing is a learning process, low vision clients, if encouraged and correctly taught, can make full use of their sight to perform tasks hitherto believed impossible, such as locating items in a supermarket.

低视力人士的定向和行动能力

低视力者的定向和行动不应该仅仅是针对完全盲人的计划的延伸。由于视觉是一个学习过程，如果受到鼓励和正确教导，低视力患者可以充分利用他们的视力来执行迄今为止认为不可能完成的任务，例如在超市中定位物品。
