Traditionally, visual acuity test charts have been constructed using the English alphabet. It is desirable to have charts made in the native language of the Chinese and Asian populations. Previous efforts in this respect have not considered the relative legibility of Chinese optotypes. In this study, twelve Chinese optotypes were constructed according to the Snellen principle and subjected to a relative legibility trial. This study provides a basis on which Chinese optotypes of near-equal legibility may be selected.
传统上，视力测试表是使用英文字母构建的。制作中文和亚洲人群母语的视力表是很有必要的。此前在这方面的努力并未考虑中文视标相对的易读性。在本研究中，根据斯内伦原理构建了12个中文视标，并进行了相对易读性试验。本研究为选择具有近乎相同易读性的中文视标提供了依据。
