A recent research has linked diabetes and vision loss. It has been claimed by a team from the Wilmer Eye Institute of Johns Hopkins University School of Medicine, that in the past 10 years, there has been an increase of 20% seen in vision loss due to diabetes in the United States.

It has further been explained that glasses cannot treat nonrefractive vision impairment, which includes glaucoma and cataracts, and it can only be healed with laser therapy or surgery. There are fair chances of a patient losing vision permanently in some special cases.

Published in the Journal of the American Medical Association, the research has asserted that those who are lurching with the disease for ten years or more are more likely to suffer from vision loss.

For the research, the team managed to nail down patients examined in 1999 through 2002 and concluded that some 1.4% of the 9,471 adults suffered from nonrefractive vision impairment as compared to 1.7% of 10,480 people tested in 2005 through 2008.

"The only (association) that got worse and got dramatically worse is diabetes, and not just diabetes, but diabetes for a long time", said David Friedman from the Wilmer Eye Institute of Johns Hopkins University School of Medicine, who worked on the study. However, there is a lot to be studied before concluding diabetes as the sole reason behind vision problems.
