As an eye health worker you will be aware of various community interventions for improving eye health. These can involve encouraging people to take better care of their eyes (e.g. specific behaviour change programmes such as encouraging hand and face washing and improving infant feeding practices) and projects that increase the number of people who make use of available services (e.g. encouraging older people to come for cataract surgery, conducting outreach programmes, providing services in the community, or mass drug distribution programmes)
