 BRACs Health Nutrition and Population Program HNPP Division is implementing this project in partnership with Vision Spring, USA. It has been an issue that whether program could use its existing Community Health Workers CHW, BRAC designated them as shasthya shebikas, here the investigators refer them as SS instead of the assigned program organizers BRAC designated, the investigators refer them as PO who had been doing the job, for conducting screening and taking more leading role in selling glasses. In BRAC health program usually these SSs are expected to work six days a week, spending two hours each day for the household visits, covering around 250 Households HHs each month, and promote behaviour change communication on various health components. SSs are non-salaried staff with lower educational level, usually with eight years of schooling. During the initial stage on their job, they receive 16 days of basic training on basic preventive, promotive and curative health care, backed up by regular monthly refreshers training. POs usually had master level degree and were regular salaried staff of BRAC as field level worker. When hired by BRAC, they receive a six days basic health and management training to be able to work as a health worker in the community. This change of role shifting, if adopted means that program can easily ensure wider coverage within a short period as CHWs are more in numbers as well as have greater access in the community. Moreover presbyopia can easily and effectively be corrected by reading glasses and certified ophthalmologists are not necessarily required for the visual correction; a lay person with low literacy and appropriate training can prescribe reading glasses for the same. It was well-understood that organizing camp has its own limitation in regards to its coverage of whole population on a regular basis. Moreover, in order to sustain the reading glass program along with the camp, a system was warranted where trained workforce could screen and suggest eye glass during their routine community visit. It was therefore, an experimental study to assess the performance of different level of workforce to screen presbyopia cases, which was necessary to bring in any changes in the service delivery model to scale up throughout Bangladesh.
