Abstract
BACKGROUND: A two-year optometry technician (OT) training was started in Eritrea in 2009 to fulfill the immediate human resource needs in providing refractive, dispensing and primary eye care services in vision centers. This study aimed to assess the current practice pattern and confidence level among the OTs.Entities:
