Literal question
608) Is anyone in your household blind or nearly blind?
IF YES: Can you tell me the name of these people?
YES 1
NO 2 (GO TO 612)
RECORD THE NAME AND LINE NUMBER OF EACH PERSON WITH VISION PROBLEMS. ASK 610 AND 611 OF THE 1ST PERSON, THEN THE 2ND, ETC.
(IF THERE ARE MORE THAN 3 PEOPLE, USE AN ADDITIONAL QUESTIONNAIRE)
