Vision problems that ca n’t be corrected with eyeglasses are on the rise among Americans age 20 and older , a new study observe . And the growing prevalence of these problem may be partly related to increasing rate of diabetes .
Researchers reported that nonrefractive visual constipation , a visual modality problem not because of the need for specs , rise 21 percent , from 1.4 percent between 1999 and 2002 to 1.7 percent between 2005 and 2008 .
The retinas of the eye may be especially sensitive to radiation from LED lights.
During the same time period , the telephone number of people withdiabeteshas climbed from 6.5 percent in 1998 to 10.7 percent in 2007 and 11.3 per centum in 2010 .
untested adults are especially at risk forvision problems , the bailiwick reported . Among non - Latino Patrick Victor Martindale White eld 20 to 39 , nonrefractive visual impairment soared by 40 percent , climing from 0.5 pct during the 1999 - 2002 period to 0.7 per centum during the 2005 - 2008 flow . While the addition may sound belittled , the generator of an accompanying editorial wrote that " with about 230 million people aged 20 years and older in the U.S. population , a 0.3 % gain could potentially represent an increase of almost 700,000 individuals with nonrefractive visual impairment over a comparatively scant metre . "
The study researcher analyzed data from the National Health and Nutrition Examination Survey ( NHANES ) , an ongoing sight of the health and nutritionary condition of Americans . This exceptional survey examine information on 10,480 masses eld 20 and older .
The most common reason of nonrefractive visual impairment in the U.S. areage - related macular decadence , cataracts , diabetic retinopathy , glaucoma and other retinal disorders , the bailiwick noted .
Diabetic retinopathy , which can affect people with Type 1 or eccentric diabetes , is because of damage to the small blood vessels in the retina , which is the light - sensitive tissue paper at the back of the eye , according to the National Eye Institute . This disorder is the leading cause of blindness in Americans 40 and elderly . Diabetes can also increase the risk of cataracts and glaucoma .
Both NHANES ' surveys ascertain that people who were old , who were live in poorness and who had been diagnosed with diabetes 10 or more years previously had the most risk for nonrefractive visual harm . However , the investigator write , " Among these peril factors , only the latter has increased in prevalence during the two time periods considered . "
An estimated 25.8 million children and adult in the U.S. have diabetes , according to the American Diabetes Association . virtually two million new case were diagnose in citizenry 20 and older in 2010
The subject findings concern serious health problem , the researchers said . " Blindness and visual impairment are associated with increase aesculapian attention expenditure , decreased work productiveness and fall quality - adjusted animation year , " the researchers wrote . " If the current finding becomes a prevail trend , it could result in increase rates of disability in the U.S. population . "
The study and editorial are print today ( Dec.11 ) in the Journal of the American Medical Association .
Pass It On : Vision problems are go up in the U.S. , partially because of diabetes .
