Purpose: To assess the use of eye care services in a rural population in North China and to analyze the factors associated with underuse of these services.
Methods: In a cross-sectional population-based study, demographic, health and vision-related information including use of eye care services were determined during a face-to-face interview. A single visit to an eye care provider qualified as "use" of eye care services.
