Ocular Nutrition And Eye HealthWritten by David Buster
Understanding ocular nutrition and eye health can be one of ways to support your vision. As early as age 30, our eyes and vision can begin to deteriorate. Wind, dust, chlorine fumes, automobile fumes, smoking, freezing temperatures and physical injury are examples of threats to healthy eyes and good vision. Long hours spent at a computer screen and vibration from driving have a cumulative negative impact on eye health over time.
Healthy vision is related to health of individual parts of eye – cornea, iris, macula, lens, optic nerve, pupil, retina and vitreous humor. And making good ocular nutrition and eye health food choices are one of ways that good vision can be supported. Information provided by U.S. National Eye Institute and results of other ocular nutrition and eye health studies have shown that using nutrition to improve and support eye health definitely happens.
Here are foods that are known to support and improve eye health:
Collard greens, kale and spinach - studies on ocular nutrition and eye health show that eating foods rich in carotenoids is associated with reduced risk of developing age-related macular degeneration. Foods rich in carotenoids are leafy green vegetables such as spinach, collard greens and kale. Macular eye nutrition becomes increasingly important as we get older.
Green vegetables and corn - another study on ocular nutrition and eye health has shown a reduced risk of developing cataracts for persons having diets higher in lutein and zeaxanthin. Foods high in these two carotenoids include broccoli, collard greens, corn, green peas, kale, romaine lettuce, spinach, turnip greens and zucchini. Lutein is also found in egg yolks. Persons with diets high in lutein and zeaxanthin were also less likely to need cataract surgery. In another study done on persons ages 40-59, those with diets high in lutein and zeaxanthin experienced a reduced risk of developing adult macular degeneration.
