 During the time of the intervention, USS were only employed in 20 sub districts where RGIL was being implemented by BRAC HNPP. To ensure USS recruitment in the study the investigators had to randomly select 6 sub-districts from these 20. Two sub districts were randomly assigned to one of the three arms through permuted-block randomization. Community people aged 35 or more, both male or female and having difficulty with near vision were invited for screening. Individuals having diagnosed eye diseases that require regular treatment and was not willing to participate in the study were excluded.
