Healthy Vision and Aging

More about World Blindness Month:

Some age-related visual impairment is genetic (if your parents wore glasses as they aged, then you are likely to need them as well), but some is environmental and is determined by your lifestyle. Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in adults over age 50. Macular Degeneration is an eye disease affecting the macula (the center of the light-sensitive retina at the back of the eye), causing loss of central vision. The Centers for Disease Control and Prevention estimate that 1.8 million people have AMD and another 7.3 million are at substantial risk for vision loss from AMD. This eye disease occurs when there are changes to the macula, a small portion of the retina that is located on the inside back layer of the eye. In its early stages, the following signs of macular degeneration can go unnoticed: gradual loss of ability to see objects clearly, the shape of objects appearing distorted, straight lines look wavy or crooked, loss of clear color vision, dark or empty area in the center of vision. In it’s more advanced stages, Age-Related Macular Degeneration can lead to severe vision impairment or blindness. Causes and risk factors include heredity. UV light exposure, smoking, poor nutrition, and lack of exercise.

While there is no specific treatment for dry AMD, studies have shown a potential benefit from vitamin supplements, a Mediterranean diet, protection from the ultraviolet light of the sun and cessation of smoking. AMD is linked to oxidative stress, autophagy decline and inflammation. Research has revealed that the polyphenol (a plant-based compound) abundant in the Mediterranean diet is responsible for lowering inflammation. This confirms what Private Home Care knows – the Mediterranean Diet is at it again! There’s no substitute for the quality of life good vision offers. Adding certain nutrients to a diet every day—either through foods or supplements—can help save the patient’s vision. A large clinical study linked lutein and zeaxanthin, omega 3, vitamin C, vitamin E and zinc to reducing the risk of AMD. Some foods in particular are important for eye health and preventing AMD, like green, leafy veggies, oily fish, and eggs.
