Behavioral Risk Factors – Vision & Eye Health

Centers for Disease Control and Prevention

“In 2013 and subsequently, one question in the core of BRFSS asks about vision: Are you blind or do you have serious difficulty seeing, even when wearing glasses? From 2005-2011 the BRFSS employed a ten question vision module regarding vision impairment, access and utilization of eye care, and self-reported eye diseases. The Vision and Eye Health Surveillance System is intended to provide population estimates of vision loss function, eye diseases, health disparities, as well as barriers and facilitators to access to vision and eye care.”

Prevalence and Distribution of Corrective Lenses among School-Age Children

“In the 1998 MEPS, 23.9% of the 5,141 children aged 6 to 18 years had corrective lenses. When weighted to the U.S. population, an estimated 25.4% (95% confidence interval, 23.8 to 27.0%) of the 52.6 million children aged 6 to 18 years had corrective lenses.”

Prevalence of Adult Vision Impairment and Age-Related Eye Disease in America

“The Vision Problems in the U.S. report and database provides useful estimates of the prevalence of sight-threatening eye diseases in Americans age 40 and older. This report includes information on the prevalence of blindness and vision impairment, significant refractive error, and the four leading eye diseases affecting older Americans: age-related macular degeneration, cataract, diabetic retinopathy and glaucoma. The estimates in this report use published prevalence rates and 2010 U.S. census data. These estimates reflect the growth and changing racial, ethnic and age composition of the United States population.”
