As one of the body's most powerful sensory organs, the eyes-like
every other human system-are at the mercy of many factors. In addition
to protecting them against harmful ultraviolet rays, getting regular
exams, and using general common sense, the eyes also have nutritional
needs that must be met.
Sadly, far too many individuals spend their lives
under the impression that, over the years, the eyes simply lose their
focus. And while it is true that the aging process can hinder how well
they function, many vision imbalances are preprogrammed in our DNA. Some
develop during adolescence, in accordance with the body's rapidly
shifting hormonal activity, while still others have their onset much
later in life.
One thing that does not change from person to
person is the importance of providing the eyes with the nutrients they
need. So unless you're among the few who are born into a world of
perfect 20/20, let's take a look at some of today's most popular and
effective eye-supporting compounds.
Beta-Carotene
Rabbits and carrots and ultra healthy vision - who
among us has not heard this analogy by now? Still, there's no denying
the fact that beta-carotene is one of the most effective nutrients when
it comes to supporting a healthy set of peepers. One of its primary
functions is to protect and condition the cornea, the thin, clear outer
layer that shields the eye's inner components from debris. Beta-carotene
is also a relentless free-radical fighter that helps protect the cells
of the eyes from oxidative damage.*
Lutein
This naturally-occurring carotenoid is commonly
found in green leafy vegetables, such as spinach and kale, as well as
egg yolks. Many systems throughout the body rely on it, with the eyes
being one of the most substantial. Since the human body is incapable of
manufacturing lutein, it must be obtained from the diet. With regard to
vision, lutein has strong antioxidant properties that help protect
ocular structures from free radical damage. It also safeguards
light-sensitive components, including the lens, macula, and retina.
Bilberry
Native to the United States and northern Europe,
these tasty berries are rich in flavonoid anthocyanosides-a powerful
antioxidant that has been shown to possess remarkable cell-protecting
properties.* A number of clinical studies have suggested that the active
components in Bilberry can support healthy night vision, while
strengthening blood vessels, staving off oxidation, and assisting the
body in adjusting from bright to dark settings.
NAC (N-Acetyl Cysteine)
This sulfur-containing amino acid plays a number of
roles within the body, including several that affect eye health and
visual integrity. One of its most impressive involves its ability to
increase the body's production of glutathione. In doing so, NAC has been
shown to provide exceptional protection against free radicals caused by
debris and other environmental factors.
Remember, the eyes are unique in that they are
extremely vulnerable and fully exposed to the world around them. This
increases their need for protection against environmental agents that
can result in injury or infection. Additionally, the head is one of the
last regions of the body to receive antioxidants, and most are used by
the body before ever making it.
