For sample persons under age 18, BLINDEV indicates if the child ever had blindness. The inquiry did not require the blindness be diagnosed by a doctor or health professional, and definitions of the term "blind " were not provided in the survey text or Field Representative's Manual and assumed to be respondent-defined.
The question for BLINDEV was part of a series of questions on child health conditions in the 1988 Supplement on Child Health.
Along with BLINDEV, respondents were asked if the child ever had any of 33 conditions, grouped in nine categories, and respondents could also specify up to three conditions not directly included in the inquiry.
Variables grouped with BLINDEV in the condition list included:
From 1997 forward, the variable BLIND, blind or unable to see at all, is available for sample children age 2 to 17 who have trouble seeing when wearing glasses or contact lenses, and sample children under age 2 who have trouble seeing.
