The Burden of Vision Loss
In 2015, a total of 1.02 million people were blind, and approximately 3.22 million people in the United States had vision impairment (VI), as defined by the best-corrected visual acuity in the better-seeing eye. In addition, 8.2 million people had VI due to uncorrected refractive error. By 2050, the numbers of these conditions are projected to double to approximately 2.01 million people who are blind, or having VI of 20/200 or worse, 6.95 million people with VI, and 16.4 million with VI due to uncorrected refractive error. (Varma 2015)
Through 2050, the number of people with VI are projected to continue to increase and remain higher among non-Hispanic white individuals compared with other racial/ethnic groups for both men and women. In 2050, the second highest number of VI cases is projected to shift from African American to Hispanic adults.

An analysis of the 1999 Survey of Income and Program Participation (CDC, 2001) revealed blindness or vision problems to be among the top 10 disabilities among adults aged 18 years and older. Vision loss has serious consequences for the individual as well as those who care for and about people who have compromised vision because it impedes the ability to read, drive, prepare meals, watch television, and attend to personal affairs. Reduced vision among mature adults has been shown to result in social isolation, family stress, and ultimately a greater tendency to experience other health conditions or die prematurely (Ellwein, Friedlin, McBean, & Lee, 1996).

During the next three decades, the population of adults with vision impairment and age-related eye diseases is estimated to double because the rapidly aging U.S. population. In addition, the epidemic of diabetes as well as other chronic diseases will contribute to an increasing population of people who experience vision loss.
