This research work determined the distribution of refractive errors among school children aged 5 to 15 years in Mgbidi,
Awgu Local Government Area of Enugu state, Nigeria. A total of 416 school children from 4 schools; 2 primary schools and
2 secondary schools were assessed. School children with cognitive problems were not included in the study. Visual acuities
were taken using Snellen’s distance visual acuity chart and Jaeger’s acuity card for far and near visual acuities respectively.
Refraction was carried out using retinoscope and trial lenses for objective and subjective refraction respectively. Spherical
equivalent was employed for cylindrical corrections. Hyperopia occurred more than myopia in the population. The hyperopia
power range of +0.25 D to < +1.00 D increased from 7.6% in the population of 3 to <8 years old, to 51.7% in the populatio.. View More»
