Should You "Supplement" Your Vision?
Do
you remember the first time you experienced the ‘trombone syndrome’?
To see anything clearly you began to extend your arm, just a little
at first and with time farther and farther, until you could go no
farther. It’s easy to joke about this universal sign of aging. But
many other eye conditions that affect adults are no laughing matter.
Many people believe thicker glasses, poorer vision and other vision
problems are just ‘normal’ signs of aging; like graying hair,
wrinkles and age spots. But, if eye problems are left untreated, a
tragic and often unnecessary loss of freedom and independence can
occur.
Diseases such as cataracts, age-related macular degeneration (ARMD)
and glaucoma will lead to poor vision and even blindness. Sometimes
there are no warning signs. Your eyes are precious and
irreplaceable! It’s important to be as attentive to them as you are
to your heart, bones, and joints: How well you see profoundly
affects the quality of your life.
The great news is that preserving your vision isn’t difficult or
time consuming. Medical studies show you can counteract free-radical
damage and protect your eyesight naturally. One Life shares the
latest scientific studies and suggestions from leading experts in
eye care to help you learn about the most common threats to your
vision and what you should be doing to help insure you see clearly
into the future.
Cataract
What is it? A cataract is a cloudy area in the normally clear lens
of the eye, resulting in progressively obscured vision. Blindness
from cataracts is preventable, yet it accounts for one out of every
seven cases of blindness in people 45 and older.
Symptoms? Common ones include cloudy or blurry vision, double
vision, problems adjusting to changes in light, poor night vision
and the need for frequent changes in your eyeglass prescription.
Can cataracts be prevented? No, but it can be delayed. Wear a
broad-rimmed hat and sunglasses with UVA/UVB protection when you’re
outdoors. Quit Smoking (numerous studies have linked cigarette
smoking with the development of cataracts). Cut back on salt (a
recent study found people whose diets were highest in salt had twice
the risk of developing cataracts. Supplement with vitamins (various
studies confirm vitamins C and E, certain B vitamins, and zeaxanthin
and lutein help reduce cataract risk).
Macular Degeneration
What is it? Age-related macular degeneration (ARMD) is a disease
that affects the macula, the part of the retina that’s responsible
for central, straight-ahead vision. ARMD is the leading cause of
legal blindness in North America. It is the most common cause of
visual impairment in people over 50, and it destroys central vision.
Am I at risk? Age is the biggest risk factor for developing ARMD.
Others include: A family history of ARMD, cigarette smoking,
long-term exposure to sunlight, hypertension, and elevated
cholesterol.
Symptoms? Slightly blurring vision is the most common warning sign.
You may need more reading light, and you may have trouble
recognizing faces until they are very close to you. As dry ARMD
progresses, you may see a blurred spot in the center of your vision
that gets bigger and darker with time.
Can ARMD be prevented? Many eye specialists feel it can. Recent
research indicates that taking anti-oxidant vitamins, especially
vitamin E, lutein and zinc are beneficial. Experts feel the
connection is free radical damage. Free radicals damage healthy
cells and are formed as a by-product of metabolism. The macula has
the highest rate of metabolism in the body. Anti-oxidants can
neutralize free radicals, preventing them from harming healthy
cells. Recent research shows promise in promoting healthy vision
with vitamin C, beta-carotene, bilberry, eyebright, Ginkgo biloba
and L-taurine.
