Significance: Provision of subsidized spectacles to schoolchildren with refractive error in Delhi was associated with increased spectacle coverage.
Purpose: Studies involving free spectacle distribution and self-purchase of spectacles often report poor compliance. We assessed 1-year spectacle coverage among schoolchildren with refractive error who were provided subsidized spectacles.
Methods: This was a study of a prospective cohort of 10,114 students from 20 randomly selected schools of Delhi. Children were presumed to have refractive error when unaided visual acuity was worse than or equal to 6/12 in either eye and a best-corrected visual acuity better than or equal to 6/9.5 in both eyes (n = 1503). Children with unmet need of spectacles (presenting with a visual acuity worse than 6/9.5 in the worse eye) were provided subsidized spectacles (n = 1191). Coverage was established by direct observation at baseline and after 1 year through unannounced visits.
Results: Mean age of cohort was 12.0 ± 2.0 years, and 566 (37.7%) were girls. Baseline spectacle coverage was 29.3% (95% confidence interval [CI], 27.1 to 31.7%), which improved to 65.9% (95% CI, 56.0 to 61.6%) among all children (n = 1470) and 58.8% (95% CI, 56.0 to 61.6%) among children with unmet need (n = 1163) at 1 year. Uptake of the subsidized spectacles was 98.6%. On multivariate regression, the odds of spectacle use were greatest when unaided vision was poor: 55.5% when visual acuity was better than or equal to 6/9.5, 74.8% when visual acuity was 6/19 to 6/60 (adjusted odds ratio, 2.5; 95% CI, 1.7 to 3.5), and 91.5% when visual acuity was worse than 6/60 (adjusted odds ratio, 3.1; 95% CI, 1.0 to 9.5). Sex (boys, 66.3%; girls, 65.3%) and socioeconomic status (lower, 58.6%; middle, 61.8%; upper middle, 70.7%) were not associated with coverage. Increasing maternal education and baseline spectacle use were associated with coverage. However, 38.0% were wearing spectacles prescribed by the project, and 61.9% of the spectacles being used at 1 year were purchased in the open market.
Conclusions: Spectacle coverage after 1 year increased through a subsidized spectacle scheme, particularly for children with poor uncorrected vision.
