Seeing Right with Ocular Nutrition

When people think of nutrition, they rarely think about their eyes. They think about their weight, and maybe their muscles, most definitely their thighs and waist. Nutrition equates to calorie counting and cardiovascular exercise, but never to eye health. Ocular nutrition, however, is as important as fighting obesity, especially when the goal is to live a long, productive and happy life. Ocular nutrition refers to the vitamins and foods that help maintain and repair the parts of the eye, including the cornea, iris, pupil and retina.

Each of these parts is essential in proper vision, but each requires specific minerals and acids to function properly. With the determination of eating habits in modern, drive-through society, most of these nutrients are missing during meal time. With a little research, however, anyone can learn the necessary supplements to make up for these absences, and give some much-needed attention to his or her eyes.

More than Carrots

Carotenoids have been proven to reduce the risks of macular degeneration related to age. Leafy vegetables and greens, including spinach, are rich in these vitamins, and can rarely be duplicated in supplements. Other vegetables, including corn and non-leafy greens, contain lutein and zeaxanthin, two carotenoids that help to combat cataracts. Lutein is also found in egg yokes, making this food essential for ocular nutrition. However, many of these foods are missing in the average diet; most meals will not include spinach, and society has developed a strong aversion to eggs.

Aside from vegetables, many fruits also contain vitamins and minerals necessary to ocular nutrition. Apricots, full of beta carotene and lycopene, promote great vision. The body converts beta carotene to vitamin A, an antioxidant crucial to the resistance of oxidation. Oxidation stresses cells and tissue, including the lenses of the eyes, causing irreparable damage in the form of cataracts or a blockage in the supply of blood to the eyes. Blueberries and cranberries are most notable for their reduction of urinary tract infections; however, both fruits can also help reduce eye fatigue and promote overall healthy ocular nutrition.

While it is always better to digest these vitamins naturally in food, for many people, such balanced meals are impossible. Both time and money can influence greatly what people eat; however, there are many supplements available to make up for any shortcomings in ocular nutrition. Most multi-vitamins contain vitamin A and antioxidants, but for carotenoids, specific formulas might have to be purchased. Fish oil, high in fatty acids, is also a good supplement for ocular nutrition, reducing the occurrence of macular degeneration and other ailments.
