Participants were evaluated using a structured questionnaire, distance Snellen chart, ophthalmoscope, and torchlight. Vision status was defined using World Health Organization categories of visual impairment based on presenting visual acuity (PVA). Data were presented in frequency tables, charts and analysed with Chi-Square statistics. All p-values reported were two-tailed and statistical significance was defined as P < 0.05. Results: The mean age of participants was 12.30± 3.14 years, while 118 (58.7%) were females. The overall prevalence of VI (PVA of 100,000.
