Eye health is important for a person's emotional and physical well-being. According to the Centers for Disease Control and Prevention, an estimated 1.8 million Americans over age 40 have age-related macular degeneration, 3.3 million over age 40 are blind and 20.5 million have cataracts in one or both eyes. In some cases, nutrient-deficiencies contribute to eye diseases. Consult your doctor before making any dietary changes or taking supplements.
Age-Related Macular Degeneration
Age-related macular degeneration, AMD, is a disease that affects the retina, causing progressive loss of central vision. It begins with hazy vision while doing simple tasks such as reading, and gradually progresses until a person sees wavy or warped lines, experiences spotty vision and, in severe cases, blindness. According to the Foundation for Fighting Blindness, vitamins A, C and E may help protect against AMD, since deficiency of these nutrients are common among those diagnosed with the disease.
Xerophthalmia or Dry Eyes
Xerophthalmia, also called dry eyes, is a disease characterized by an inability of the eyes to create proper amounts of moisture. The eyes may produce too few tears or tears of poor quality. Dry eyes may be caused by imbalances in tear composition, medications and environmental factors. According to the Linus Pauling Institute at Oregon State University, severe or prolonged deficiency of vitamin A may also lead to dry eyes. Adults over age 50, women after menopause and people who have had laser eye surgery may be at a heightened risk for the disorder.
Cataract Eye Disease
Cataract eye disease, often simply called cataracts, involve the clouding of the lens of the eye. Cataracts develop gradually and in time, they interfere with the ability to see details, read small print, drive or see efficiently at night. In addition to genetic factors and the aging process, deficiencies of vitamin C and E may heighten risk for cataracts, according to the Office of Dietary Supplements. In addition, increased vitamin E intake may slow the progression of cataracts once they arise.
Corneal Ulcers and Blindness
Corneal ulcers are open sores on the cornea—the thin clear structure atop the colored part of your eye, known as the iris. Though most corneal ulcers are caused by bacterial infections, particularly in people who wear contact lenses, vitamin E deficiency may contribute, according to the Linus Pauling Institute. Vitamin E deficiency may also lead to partial or total blindness.
