Abstract: this study examines how yorùbá language braille code can enhance fast reading and comprehension of learners with visual impairment in nigeria. The study employed quasi experimental design of the pretest, posttest and control group. The total population for the study was 50 learners with visual impairment in junior secondary school for the blind and inclusive junior secondary school in southwest nigeria. Purposive sampling technique was used for the selection of 23 respondents where 13 respondents from commercial grammar school oke-iho in oyo state were used as experimental group and 10 respondents from ondo state school for the blind were used as control group. The instruments used for the study were Yorùbá Language Braille Code (YLBC), Yorùbá Literature Achievement Test (YLAT) and Yorùbá Lesson Plan (YLP). Kuder Richardson formular (KR20) was used for the reliability, and the coefficient r=0.97 was obtained. The data collected were analyzed using ANCOVA. The study revealed the significant effects of braille code for Yorùbá toned alphabets and those taught with conversional Yorùbá alphabets. It was revealed that there is a significant effect of braille code for Yorùbá toned alphabets and those taught with conversional Yorùbá alphabets (F(2, 23) = 1.822; p<0.05, partial η2 = 0.002). It also revealed the significant main effect on onset visual impairment students taught with braille code for Yorùbá toned alphabets and those taught with conversional Yorùbá alphabets (F(1, 24) = 5.16; p<.05, partial η2 = .27). The study recommended that training and retraining programs such as seminars, workshops and symposia, should be organized to train teachers of students with visual impairment and how to teach with it.
