There’s a study from Journal of the American Medical Association that there’s increasing number of people losing their sight from conditions such as diabetic retinopathy, macular degeneration, cataracts and glaucoma. Research from University School of Medicine found that the result could increase rates of disability in the United States.
The study included 9,471 people ages 20 and older. Most of the participation are part of the National Health and Nutrition Examination Survey between 1999-2002 period and the 2005-2008 period. 1.4 percent of those people had these kinds of visual impairments between 1999 and 2002, compared with 1.7 percent of people between 2005 and 2008. The non-hispanic white people between ages 20 and 39 had a 40 percent increase in nonrefractive visual impairments with the prevalence going up from 0.5 percent in 1999-2002 to 0.7 percent in 2005-2008/
The report show that factors such as diabetes, poverty and lower educational level are all linked with these kinds of visual impairments.
