Vision Loss at Old Age Becomes a Growing ConcernNovember 30th, 2011 at Wed, 30th, 2011 at 5:17 pm by timigustafson
Aging baby boomers worry more about losing their eyesight than almost any other disease, including heart attack, stroke and cancer. But most have little knowledge about the causes of age-related vision loss or prevention measures they could take, according to a recent report titled “Eye on the Boomer.” For the survey, which was sponsored by Bausch & Lomb, a global eye health company, 1001 randomly chosen participants, ages 45 to 65, were interviewed via telephone about their concerns for their vision. 78 percent said they valued good eyesight more than any other of their senses. But almost half of the respondents admitted they didn’t get annual eye exams. Even fewer were aware that the quality of their nutrition and lifestyle choices played an important role for their eye health.
“If people are at risk for heart disease, they typically make lifestyle modifications. This survey found that people are as concerned about their eyes but do not know the simple steps they need to incorporate into their daily lives to take care of them,” said Dr. Jeffrey Anshel, OD, FAAO, president of the Ocular Nutrition Society (ONS), which published the study.
According to the National Eye Institute (NEI), the number of Americans with vision problems will double over the next three decades as the baby boomer generation reaches old age. The growing demand for eye health services will add yet another significant burden on the health care system, especially since eye diseases are often related to diabetes, which is already reaching epidemic proportions in this country.
Unfortunately, the diet most Americans adhere to lacks many essential nutrients that could help protect their eye health. For example, omega-3 fatty acids, richly found in salmon and other coldwater fish, are highly beneficial for the eyes. So are the carotenoids, lutein and zeaxanthin, which are present in eggs and many green leafy and collard vegetables. Both of these nutrients defend cells in the body from the damaging effects of so-called “free radicals” and protect the eyes from developing macular degeneration and cataracts.
Because of notoriously low consumption of fruits and vegetables, many Americans do not get sufficient amounts of carotenoids for most of their lives and the negative effects become apparent as they age. Smoking and high alcohol consumption can diminish carotenoid levels in the blood stream, adding to the damage. People who take cholesterol-lowering medications may be at risk of lacking carotenoids because of reduced nutrient absorption.
For these reasons and others, taking daily vitamin supplements to bridge nutritional gaps is highly recommended. Good supplemental sources for lutein and zeaxanthin come from marigold flowers. Preferable would be whole food sources like kale, spinach, turnips, broccoli, romaine lettuce, zucchini, Brussels sprouts and peas.
“As we grow older, the need for certain vitamins and nutrients to support the eye increases,” said Dr. Anshel. “Over the past couple decades, there has been a national focus on better nutrition and healthy living. This survey highlights the need for greater education on lifestyle modifications that baby boomers should be incorporating into their daily lives, including proper nutrition, to safeguard eye health as they age,” he added.
