The purpose and scope of the study: This study aimed to develop and validate a Traditional Chinese reading chart for students with low vision in Taiwan. The method used: The Traditional Chinese reading chart for students with low vision in Taiwan was developed regarding the two principles. The main design concept was the principle of continuous text, however some unrelated words were used to avoided semantic and syntactic context. Sighted subjects (n=10) ages range between 23 - 29 years old (M= 25.8±1.7), visual acuity 0.0 logMAR (SPH: -2.30±1.37D; CYL: -0.68±0.56D). The subjects were recruited from Taiwanese students who study in University of Tsukuba, Japan. The reading performance investigated on 14 differences in characters size (0.0 logMAR – 1.3 logMAR) and 20 reading items were measured. A summary of results: one way ANOVA analysis result demonstrated that the reading speed in 0.0 logMAR and 0.1 logMAR were significantly slower than other character sizes (F (13,126) = 25.389, p < .01), and reading item No. 4 was significantly slower, item No. 6 and No. 11 were significantly faster than other reading items (F (19,180) = 1.571, 0.05 < p < 0.1). Therefore, the character size in 0.0 logMAR and 0.1 logMAR, and 3 reading items namely No. 4, 6, 11 were removed. (4) Conclusions: We developed and validated a Traditional Chinese reading chart in 12 characters size and 17 reading items for investigation reading performance in Traditional Chinese with reading ability.
