Aging
may cause common eye problems, which are related to how your eyes are shaped
and which accordingly affect how you focus with your eyes.
These
common problems include nearsightedness (an eye condition in
which your eyeball is too long, such that light rays fall short of achieving a
point of focus on your retina, which is the sensory membrane at the back of the
eye), farsightedness (also known as hyperopia, a
condition in which you can see distant objects very well, but have difficulty
focusing on objects that are up close), and astigmatism (a
condition in which your eyes have an irregular shape, causing light rays
entering your eyes to split into different points of focus, and thus resulting
in blurry vision).
When
you "exercise" your eyes, you move your eye muscles to create
up-and-down, side-to-side or circular motion. These movements "work"
the muscles controlling back-and-forth movement of your eye's natural lens, to
help achieve sight at multiple distances. In addition, eye exercise can
change the basic shape of your cornea, thereby instrumental in changing the
angle of light entering your eyes for better and more correct focus.
Macular
degeneration is another serious eye problem affecting
as many as 30 million Americans aged 65 and above. If you are 65, you have 25
percent of developing macular degeneration; and your risk increases to 30
percent if you are over 75.
The
macula is a small central part of the retina that enables detailed vision. As
such, it is critical to your vision health. Unfortunately, the macula may
degenerate due to various reasons, such as heredity, hypertension, high
cholesterol, sun damage, and smoking. Macular degeneration is a slow,
progressive disease that affects both eyes, typically one after the other. Due
to its slow development, macular degeneration may take years to become
noticeable. By the time you notice it, the onset is already well underway.
Therefore, prevention is always better than cure. Vision health is an important
component of self-healing of the eye.
Like
many other diseases, macular degeneration can be treated with high doses of
antioxidants and minerals. With the exception of vitamin D from sunlight, your
body does not make your own vitamins and minerals; they must be obtained from
your diet. Antioxidants and vitamins and minerals are critical to vision health
in preventing and treating generative diseases, such as macular degeneration.
You need high doses of beta-carotene, vitamin C, vitamin E, and zinc.
Nutritional therapy is an important component of natural self-healing and
vision health. Beta-carotene facilitates your body to convert plants into
vitamin A, thereby instrumental in boosting normal cell reproduction in the
eye, protecting the eye from free radicals, and enhancing night vision, Vitamin
C is an important immune system booster, and an agent for making collagen to
maintain healthy blood vessels in the eye. Vitamin E is a potent antioxidant to
protect cell membranes. Zinc is a mineral required by more than 300 enzymes to
repair wounds, to optimize vision health, and to protect the eye from free
radicals.
Nutritional
therapy also includes supplements of lutein, Taurine, DHA, and ginkgo biloba.
Lutein is a carotenoid found in vegetables and fruits, such as collard greens,
kale, and spinach. Lutein promotes vision health through its potent antioxidant
properties. Taurine transports nutrients to the eye as well as eliminates toxic
accumulation in the eye; it promotes retinal health and night vision. DHA,
which is an essential Omega-3 fatty acid, enhances the development of the
retina. Ginkgo biloba is an ancient Chinese herb for vision health.
Natural
physical health requires exercise and nutrition; by the same token, your
natural vision health also requires regular eye exercises and nutritional
therapy to maintain and sustain its quality.
