Interviewer instructions
This set of questions serves as screening to help identify respondents who may have a current vision problem related to cataracts, and is asked to everyone aged 60 or over. An answer of “yes” should be recorded only for respondents who have experienced these vision difficulties in the last 12 months.
If the respondent does not understand what is meant by cloudy or blurry vision, read the following:
“Cloudy or blurry vision refers to when you cannot see clearly, as if there is a fog in front of your eyes, or as if you are trying to see through a waterfall, or the image has been smeared so you cannot see optimally.”
