Most dramatic is the rise in diabetic retinopathy, says Jeff Todd, chief operating officer of Prevent Blindness America, which issued the report.
In the past 12 years, it has risen an alarming 89%, Todd tells WebMD. Nearly 8 million people ages 40 and above now have it.
"We suspect that is largely due to the spike in diabetes and the diabetes epidemic we are facing as a country, as well as the increase in Hispanic and African-American populations, which tend to have a higher rate of diabetes," he says.
More than 2 million age 50 and older are affected now.
The report, titled "Vision Problems in the U.S.," was released today by Prevent Blindness America and the National Eye Institute.
Vision Problem Report Details
These reports are issued periodically, using Census data and new research. For the current update, the researchers compared the current number of Americans with vision problems with the numbers from 2000.
- A 19% increase in cataracts, with more than 24 million people age 40 and older affected
- A 22% increase in open angle glaucoma, with nearly 3 million people age 40 and older affected
Cataracts, more common with age, are a clouding of the eye's lens.
Glaucoma is an increase in fluid pressure in the eye. It can damage the optic nerve and lead to blindness.
About 1.3 million Americans are blind, the report says.
Another 2.9 million have low vision. This is a loss of eyesight that makes everyday tasks such as reading difficult.
Another 34 million, ages 40 and older, have myopia, or nearsightedness.
As the number of Americans with vision problems has been increasing, Todd tells WebMD, funding for research and education programs has been slashed. Last year, the CDC saw its research funding dip from about $3.2 million to about $500,000, he says.
Eye Disease Report: Perspective
The rise in diabetic retinopathy is ''scary," according to Anne Sumers, MD, a clinical correspondent for the American Academy of Ophthalmology. She reviewed the report findings for WebMD.
"It's proof we are in a losing battle," she says. Many of the people affected, she says, are in their prime working years, risking vision loss.
The rise in macular degeneration, she agrees, mirrors the booming aging population.
Protecting Eye Health
Getting regular eye checkups is a good start to protect your eye health, says Sumers, a Ridgewood, N.J., ophthalmologist.
So are regular checkups, especially a check of blood glucose, to be sure you are not in early stages of diabetes, she says.
"Talk to your primary care provider about what you are most at risk for," Todd says.
He notes that ethnic groups differ, in general, in their risk for specific eye diseases.
While whites have a higher risk of macular degeneration than other groups, African Americans, Hispanics, and Asians often have higher rates of glaucoma, he says.
The rates of diabetes are higher in African-Americans and Hispanics than in others, he says.
Eating healthy can help your eyes, too, he says.
