It is never easy to assess accurately the vision of an illiterate child. Children under the age of 3 who are unable to understand and co-operate with tests using shapes and a key card present an even greater problem. All available subjective tests for this age group may maintain a small child's interest, but the accuracy of the recorded vision is very much in doubt. The new test described below is designed for 2-3-year old children. It combines the well recognised advantages of using pictures to gain the child's attention with the accuracy of a graded test based on Snellen's chart sizing. It is therefore both a practical and more accurate alternative test for this age group.
准确评估一个文盲儿童的视力绝非易事。3岁以下无法理解并配合使用形状和视力检查表进行测试的儿童更是个大难题。针对这个年龄组的所有现有的主观测试可能会保持幼儿的兴趣,但所记录视力的准确性很值得怀疑。下面描述的新测试是为2至3岁的儿童设计的。它将利用图片吸引孩子注意力这一公认的优点与基于斯内伦视力表尺寸的分级测试的准确性结合起来。因此,对于这个年龄组来说,它是一种既实用又更准确的替代测试。
