Codes and Frequencies
For sample adults age 18 and over in 1999 and age 55 and over in 1984, CATARACTNOW indicates if the respondent had cataracts at the time of the interview.
The 1984 Field Representative's Manual described now as "present at any time during the past 2 weeks through the last Sunday before the interview." The 1999 Manual did not provide a definition for "now," but the time frame is assumed to be the same. While neither of the Manuals provided a definition of cataracts, it is a condition that causes clouding of the eye lenses that results in a loss of clear vision.
