Macular degeneration is one of the three main culprits of blindness in old age, along with glaucoma and diabetic retinopathy. Statistics show that the prevalence rate of macular degeneration is as high as 15.5% among the elderly over 50 years old and 20.2% over 70 years old. In other words, about 1 out of 7 people over 50 years old is a patient with age-related macular degeneration. The cause of age-related macular degeneration is still unclear, but a large number of studies have shown that the occurrence of age-related macular degeneration may be related to age, genetics, environment, smoking and other factors. Women are more prone to the disease than men, and people over the age of 50, those with a history of diabetes, hypertension and hypercholesterolemia are all at high risk for age-related macular degeneration. Therefore, the Macular Degeneration International Consortium recommends that people over the age of 55 receive an annual fundus examination. In addition to medication, it is recommended to take some antioxidants and supplement with supplements with antioxidant power and rich in vitamin C and vitamin E, which can prevent cell damage by free radicals, protect the visual cells and act as a retinal tissue nutrient. Clinical studies have shown that long-term use of eye health drugs containing lutein, trace elements of zinc and multivitamins and unsaturated fatty acids can help prevent the development of macular degeneration. Experts point out that the likes of corn, spinach, cilantro, tomatoes, sweet potatoes and citrus are leaders in containing lutein, the antioxidant vitamin C and vitamin E. Eating more of these brightly colored vegetables and fruits can help delay the development of eye blindness or vision loss due to degenerative changes in the macula of the elderly. Studies at Harvard Medical School in the United States have shown that people who eat large amounts of these foods daily are 43% less likely to develop age-related macular degeneration.
