Sixty-six (79.5%) of subjects had a form of refractive error; 63.6%%, 16.7% and 19.7% were myope, hyperope or simple estigmat, respectively. The prevalence of ametropia was 82% in female and 78% in males. The association between refractive errors and gender was not statistically significant (p = 0.35, 95% Confidence Interval [CI], 0.34-0.36).Minus spherical errors ranged from -0.16 to -5.25 diopters (D) and plus spherical errors ranged from +0.25 to +1.00D, spherical equivalent between -0.25D and - 2.75D being the most common type (85.5%). Eight students (12.1%) were wearing glasses at the time of the study corresponding with 10 (15.2%) who had eye pains while reading.
