In this paper we describe a method for the preliminary assessment of the illumination needs of partially sighted individuals. The method is based on determining the smallest readable lettersize under different levels of illumination. Half of the partially sighted in our population had a performance that was dependent upon the level of illumination. At the same time, most of those for whom no improvement in performance was found, did express a preference for a certain level of illumination. Therefore, there remain discrepancies between the objectively determined optimal level and the preference for a certain level. We conclude that the current method is a useful but insufficient method of determining the illumination needs of partially sighted individuals.
在本文中，我们描述了一种初步评估弱视个体照明需求的方法。该方法基于确定不同光照水平下最小可读字母大小。我们研究群体中一半的弱视个体其表现依赖于光照水平。同时，大多数在表现上未发现改善的个体，确实表达了对特定光照水平的偏好。因此，在客观确定的最佳水平与对特定水平的偏好之间仍存在差异。我们得出结论，当前方法是确定弱视个体照明需求的一种有用但不充分的方法。
