Presbyopia is a refractive error (RE) that causes near visual impairment with advancing age. Uncorrected presbyopia significantly affects near vision-related quality of life of individuals who depend on near work for livelihood, be they literate or illiterate. This study is aimed at finding the prevalence of presbyopia in patients who presented with refractive error in Adoose specialist hospital, Jos. Materials and Methods: Records of all patients who presented at the hospital from 2000 to 2009 with symptoms of functional presbyopia, defined as requiring at least + 0.75 dioptre in order to read the N8 optotype at a distance of 40 cm in the patient's usual visual state were included in the study. The eye with the better presenting visual acuity was used for classifying the patients. Results: There were 912 patients with RE. Of these, there were 482 (52.9%) subjects whose visual acuities improved to N8 optotype at a distance of 40 cm with refraction. There were 265 (55%) males and 217 (45%) females. The mean age of patients at presentation was 47.8 ± 8.2 (range 35-80) years. Most of the patients (77.1%) complained of problems with near visual tasks. Seventy-five (15.7%) subjects presented with glasses of inappropriate corrections that was causing visual strains. Presbyopia showed a significant increase with increasing age. The power ranged from +0.75 to +4.0D (with a mean of 2.08). The most frequent power was +2.0D. The civil servants 257 (53.3%) formed the highest number of subjects seeking presbyopic correction. Plano-presbyopia was the commonest presentation at 51.6% and it showed a significant decrease with increasing age. This was followed by hypermetropia − presbyopia at 32.6% which increased with the increasing age. There were fewer subjects (15.8%) with myopia-presbyopia. Conclusion: This study has shown that presbyopia presents early and is a problem in our society. Economic consequences are likely to be considerable, as uncorrected presbyopia affects people in the working-age group.
