To measure the spectacle use and the quality of life gained by vision correction and use of spectacles; to analyse the costs and cost drivers of vision screening in integrated school health programmes; and to analyse the budget requirements for sustaining and extending the intervention to other geographical locations.

Better programming and evidence-informed resource allocation decisions on school health initiatives.
