A friend of mine recently let his contacts stay in their antibacterial
pool longer than usual and embraced his new pair of glasses like a long lost
friend. After complimenting him on his new purchase, I tried them on only to
hear him tell me not to look through the lenses because he was “blind as a bat”
and my eyes would end up in pain. Aside from thinking I should have my own eyes
checked after almost a decade, I also wondered if there were any natural ways
to keep my eyes healthy.
Carrots have long been thought of as an old wives tale of
chomping on good-for-you vegetables masquerading as cures, but there is merit
to the humble carrot. Carrots contain beta-carotene which is transformed into
vitamin A by the body. Sure excess amounts of vitamin A may not ensure 20/20
vision, but it can help you maintain good eyesight. You can also get vitamin A
from liver, broccoli, kale, sweet potatoes, pumpkins, mango, apricots, and
cantaloupe, but carrots are best known for helping the eyes.
Beta-carotene isn’t the only compound found in carrots that
is helpful—an antioxidant called lutein that primarily works with another
component called zeaxanthin—and eating foods rich in these nutrients can
increase the pigment density in the macula and added protection for your
retina. Most of the foods with both of these nutrients are of the green and
leafy variety.
As we age, our eyes get weaker and while over half of all
Americans over 80 years of age have cataracts, over 13 million Americans are
suffering from macular degeneration. The macula, part of the eye that helps
keep the cones and rods in proper working order, has been under the microscope
lately because a new study has linked vitamin B supplements to helping those
with age-related macular degeneration. Macular degeneration is a widespread
disease that attacks the area central to the retina and is a leading cause of
vision loss in people over the age of 50.
A deficiency in vitamin A can also cause vision loss.
Professor of Nutrition at Ohio State University, John Allred, says that extreme
deficiency can cause night blindness and can even cause complete blindness, and
is the leading cause of blindness in the third world alone. However, Allred
says, if you are not deficient, drinking carrot juice every day or other
beta-carotine enhanced veggies won’t improve your vision, only maintain it…and
cause your skin to turn orange.
Beta-carotene, besides being broken down as a helpful
vitamin within the body, is also a pigment. Experts say not to worry because
even though the skin might appear to have an orange tint, it is completely
harmless. If you cut back on the orange foods or drinks or consult your doctor
to make sure your diet is balanced correctly, the tint will eventually lessen
and go away and the excess of beta-carotene in your system will flush itself
out. If you would rather not risk getting your vitamin A-carrying beta-carotene
through orange tinted foods, most multi-vitamins include the nutrient for a
quick source and readily available.
Unfortunately I did not find any helpful hints to share with
my sight-challenged friend; I was pleased to find out that the urging of
mothers everywhere to “eat your carrots” was not all a ruse. While I am still
thinking of making an eye appointment and I am not 100 percent sure that my
weekly carrot cake cravings are actually helping to keep my eyesight on a
steady plateau, my eyes haven’t failed me yet and as long as my multi-vitamin
can help me out, I will not worry about my eyes for now.
