From the 2002 National Health Interview Survey:

> Do you have any trouble seeing, even when wearing glasses or contact lenses?

> Do you use any vision rehabilitation services, such as job training, counseling, or training in daily living skills and mobility?

Persons who respond "yes" to having trouble seeing and to using any vision rehabilitationservice meet the criteria for the objective.

Data (except those by education status) are age adjusted to the 2000 standard population using the age groups 18-24, 25-34, 35-44, 45-64, and 65 years and over. Data by education status are adjusted using the age groups 25-34, 35-44, 45-64, and 65 years and over. Age-adjusted rates are weighted sums of age-specific rates. For a discussion on age adjustment, see Part A, section 5.

For some measures, data do not meet the criteria for statistical reliability, data quality, or confidentiality and have been suppressed. Information on suppression of data for the major Healthy People 2010 data systems has been published in a Healthy People Statistical Note report (Klein, R.; Proctor, S.; Boudreault, M.; Turczyn, K. Healthy People 2010 Statistical Notes No. 24. 2002).
