Cataracts are the leading cause of reversible vision loss as we age. According to Prevent Blindness America, more than half of all Americans have them or have had surgery for them by the time they reach 80. The condition causes vision to become progressively clouded; a process that happens so
Changes in eye prescriptions are not the only vision issue adults face as they age. A new study in Optometry and Vision Science reports that older adults show a high rate of anisometropia, or unequal vision, which can be a leading contributor to disabling falls.
In the study, researchers analyzed vision
Astigmatism, for a relatively common eye condition, is not an especially well-understood term. Simply put, it’s a condition that results when your cornea is irregularly shaped.
Because of this condition, light can’t focus on the retina in the back of the eye, making it harder for you to focus on
Can what you eat affect your eyesight? And which foods protect your eyes? Research shows that three particular carotenoids, each of them antioxidant and anti-inflammatory compounds, play a role in good vision: lutein, zeaxanthin, and astaxanthin.
Studies verify that astaxanthin protects the eyes against damage and daily wear-and-tear, decreases eye
Busy lifestyles and processed foods and beverages cause nearly all of us to become chronically deprived of water and susceptible to the dangers of dehydration. Although they are not the only organs affected by lack of water, the brain and eyes are especially vulnerable to the following conditions:
Obstruction of blood
The importance of the neurotransmitter serotonin in affecting mood has been widely acknowledged in numerous studies linking low brain levels of this key chemical with depression, anxiety, and irritability. Now, scientists are reporting another significant role the neurotransmitter plays in the brain—that of promoting memory and cognition.
Inadequate brain levels of
Bored with broccoli? Had it up to here with green beans and asparagus? Seen enough carrots and peas to last a lifetime? Maybe you need to branch out a little in the produce aisle.
“Some often-overlooked vegetables deserve a second glance for their nutritional benefits,” says Jeffrey B. Blumberg, PhD, Tufts
Multivitamins and Your Brain
For many Americans, taking a multivitamin as “insurance” against nutritional shortfalls is a daily habit. Americans have been taking multivitamin/mineral supplements since the early 1940s, and an estimated one-third of all U.S. consumers take these regularly. Multivitamins account for almost one-sixth of all purchases of dietary supplements
There was a time when eyecare specialists could do nothing to stop the advance of age-related macular degeneration. Advances in medical therapy offer the potential of halting the vision loss associated with age-related macular degeneration and, in some instances, restoring lost vision. But what is age-related macular degeneration, and what
Alzheimer’s disease (AD) affects 5.1 million Americans, and there is currently no cure. However, neurologist Sam Gandy, MD, PhD, director of Mount Sinai’s Center for Cognitive health and NFL Cognitive Care says that there are some hopeful developments in AD research—along with potentially promising data you may have seen reported
