Considering visual acuity of less than 6/6, in the right eye, most of the students presented with visual acuity 6/9 (16.8%), followed by 6/12(3.2%) and 6/6 partial(3%). Similarly in the left eye, most of the students presented with visual acuity 6/9 (24.2%), followed by 6/6 partial (3.8%) and 6/12(3%).
