Interviewer instructions
During pregnancy, especially in the third trimester, a woman may suffer from night blindness due to vitamin A deficiency. Night blindness is a condition in which a person has more difficulty than normal seeing when it is dark or in low light conditions. In Q. 424 ask the respondent whether she suffered from problems with her vision during the day, for example, blurred vision. Do not include problems such as near-sightedness or far-sightedness which the woman had before the pregnancy. In Q. 425 ask her about night blindness. Be sure to use the local term for night blindness so that the woman understands what condition you are referring to.
