§ Mr. KirkwoodTo ask the Secretary of State for Health what is the expected cost of the NOP survey into the volume of sight tests in the first quarter of 1990; and what was the survey method used.
§ Mrs. Virginia BottomleyThe questions on sight test take-up were included as part of the regular NOP weekly omnibus survey. They were repeated over a five-week period and provided a random sample of some 10,000 adults. The cost of the survey is a commercial matter between the Department of Health and NOP.
