The results of this study indicated that children do use and benefit from low vision aids and that the child's need for near low vision aids can be predicted from their age, unmagnified reading performance, and visual field characteristics. The use of distance monoculars is less easily predicted. However, many visually impaired children both in mainstream special units and in schools for the blind are not being supplied appropriate low vision aids (LVAs). Many have not had an LVA assessment within 1 year and others are experiencing difficulties with LVAs that could be eliminated or reduced.
这项研究结果表明，儿童确实会使用低视力辅助器具并从中受益，而且儿童对近用低视力辅助器具的需求可以根据其年龄、未放大状态下的阅读能力以及视野特征来预测。而对远用单筒望远镜的使用则较难预测。然而，许多在主流特殊教育机构和盲人学校中的视力受损儿童并未得到合适的低视力辅助器具。许多儿童在1年内未进行过低视力辅助器具评估，其他儿童在使用低视力辅助器具时遇到的问题本可以消除或减轻。
