There are many common misconceptions about eyesight. The generally accepted thinking is that eyesight deterioration is inevitable as we age. Nothing could be further from the truth! With aging, it is natural for the circulation in your eyes to get sluggish. The lenses of your eyes start to lose their elasticity and adjusting to glare, and darkness is more difficult. Many people find that it is harder to read small print or see clearly when driving under very bright, sunny conditions or at night when it is very dark.
There is evidence that these problems happen not because of aging, but because of damage from pollution, UV from the sun, (ultraviolet rays) or from Oxygen damage. (Free radicals.) Here is how it happens:
Your eyes have nerve tissue, blood vessels, and highly specialized retinal cells which are constantly being bombarded by ultraviolet radiation. This leads to radiation and free radical damage and is responsible for most deteriorating vision problems. To make it worse, light entering your eyes which stimulates your retina cells accelerates this free-radical damage and vision loss. Overexposure to pollutants, light, and oxygen will cause more damage to your eyes than to any other organ in your body.
Research has shown that you can effectively fight off free-radicals and radiation by taking nutritional supplements. One study showed that patients with a clouding lens were given a combination of bilberry extract and vitamin E which stopped the progress of this eye problem in 97% of the participants! Additionally, a special group of chemicals found in dark, leafy vegetables (carotenoids) such as spinach also have very powerful antioxidant properties. These are fat-soluble phytochemicals. Studies show they can give you a 43% greater protection against retinal damage!
Ginkgo Biloba has also been in the news a lot recently, and with good reason! This flavonoid-rich herb has been shown to increase the blood flow to the tissues and tiny capillaries in your eyes. It also helps maintain the flexibility and elasticity of those capillaries. Amino acids also play an important role in your eyesight, particularly L-Taurine. By helping to filter out damaging ultraviolet radiation L-Taurine acts like a pair of sunglasses.
