Nowadays, more and more people begin to notice the importance of nutrients for eyes. In some cases, particular nutrients can be used to treat and prevent some eye diseases. For example, as people get old, their eyes will degenerate correspondingly. And the aging process can be slowed down by taking some kinds of nutrients. Here is some information about such nutrients that can reduce the risk of some eye problems.
The first one should doubtless be antioxidants. Aging process is the result of oxidation. And antioxidants can be used to stop or slow down this process. The aging process of eye tissues and cells can also be slowed down with antioxidants. For example, some oxidations can cause cataracts and blurriness. And the antioxidants will be effective to fight against these diseases. Some fruits and vegetables are abundant with antioxidants, such as vitamin C, E, A and carotenoid.
As for old people, Vitamin C is essential for their vision because this nutrient can prevent cataracts and macular degeneration. Glaucoma can also be avoided by taking sufficient Vitamin C. Then, how to get this nutrient? In fact, some common fruits like oranges, lemons, are rich in it. Of course, vegetables like spinach, peas, and tomatoes, etc. are also rich in Vitamin C.
Vitamin E is also a very important nutrient for eyes, such as, Cataracts and macular degeneration can be avoided by taking enough of it. Foods like egg yolks, tomatoes, sunflower seeds, etc. are rich in this nutrient.
Some people have cataracts and night blindness, and they are suggested to eat foods with more Vitamin A which can also be used to prevent corneal ulcers. Liver, sweet, potatoes, etc. are foods that contain a lot of it.
In people’s eyes are some pigments that are mainly composed of carotenoid. While the light coming into the eyes, these pigments will react with it and offset the potential damage to the eyes. So carotenoid can be used to filter out the harmful sun light. Tomatoes, salmons, oranges, etc. are foods that contain a lot of carotenoid.
Another important and effective antioxidant is called Omega-3 fatty acids. If people can intake sufficient Omega-3 fatty acids, they will run much lower risk of getting macular degeneration. It can also be found in some foods, like shrimps, snapper, salmon, etc.
Still, there are also some minerals that are essential for eye health, such as zinc, lutien, etc. These minerals can strengthen the power of Vitamins.
