Children's visual impairment and visual care related to socioeconomic status in Catalonia (Spain).

For the first time, indicators related to visual impairment in children in Catalonia have been recorded. There is an association between lower socioeconomic status and having non-correctable visual impairment, and conversely, having correctable visual impairment was significantly associated with employed parents. More visual care is associated with higher socioeconomic status.
