“The eyes are the mirror to the soul.” The meaning of this proverb is that the expression in a person’s eyes reveals the underlying emotions experienced by that person. Additionally, our brains use visual stimuli to process information and make decisions. Owing to the latter reason, it is essential to keep our eyes in good condition and prevent any type of degeneration of the eye.
Effective nutrition is vital to keep the body fit and healthy. Certain foods are rich in nutrients that help in maintaining healthy eyes and reducing age-related degeneration of the eye. It is advisable to consume the recommended intake of these foods. A few of these eye nourishing foods are described in the rest of this article.
Dark leafy greens like spinach and kale are rich in the carotenoids lutein and zeaxanthin. The zeaxanthin as well as Lutein benefits are numerous. The macula, the tiny central part of the retina, has a large amount of these two nutrients. The function of the macula includes central vision and fine detail in vision. As a person ages, the degeneration of the macula can occur resulting in a significant loss of central vision. There is a considerable amount of evidence that a diet rich in lutein and zeaxanthin can mitigate the age-related damage in the macula. Blue light, which can cause oxidative damage to the macula, is absorbed by lutein. Additionally, evidence suggests that these two nutrients can reduce the risk of developing cataracts.
A good source of lutein, zeaxanthin and Vitamin A, eggs can boost eye health tremendously. A diet rich in eggs can prevent night blindness and dry eyes. Although the concentration of lutein and zeaxanthin in eggs is lower than in leafy greens, age-related macular degeneration can be prevented by regular egg consumption.
Packed with omega 3 fatty acids and Vitamin E, a powerful anti-oxidant, nuts like pistachios, almonds and walnuts help prevent eye disease and reduce the loss of vision while aging.
Carrots, tomatoes, guavas, and strawberries, are very good sources of Vitamin A and Vitamin C. While Vitamin A boosts vision, Vitamin C is an excellent anti-oxidant which reduces the oxidative damage caused to the eye while aging.
Sardines, mackerel, salmon and tuna are a remarkable source of omega 3 fatty acids. Healthy eyes require a diet with a high concentration in these fatty acids.
Given the varied food sources rich in nutrients that are beneficial to the eyes, people should make the best use of these foods to maintain optimum eye health.
