vision problems are on the rise -- and diabetes may be to blame.
a new study out of johns hopkins university found nonrefractive visual problems -- like macular degeneration and glaucoma -- went up twenty percent from 1999 to 2008.
risk factors for these eye conditions include old age, poverty, and diabetes.
the only factor that has changed during the study period is diabetes -- with cases of the disease going up significantly.
experts say this study shows diabetes is causing a spike in vision problems throughout the u-s, and doctors should be on the lookout for early signs of the impairment.
