        <p>A common vision disorder experienced by many, alongside myopia
and hyperopia (near- and farsightedness), is astigmatism.</p>
<p>Â Â Â Â Â Â Â Â Â Â Â Â Astigmatism affects over 40 million Americans
and is caused by an irregularly shaped cornea. When the cornea, which
acts as a window, is a spherical shape it focuses light correctly upon
the retina at the back of the eye; this produces sharp images at all
distances. Conversely, in instances where the cornea takes on a more
oval shape, the light is focused at two retinal locations rather than one
and blurry vision is the result. Corneal irregularities can occur at
birth or be the result of injury or trauma. It often happens in
conjunction with the above-mentioned myopia or hyperopia.</p>
<p>Â Â Â Â Â Â Â Â Â Â Â Â Eyeglasses or LASIK surgery are options for
treating astigmatism, but a more popular choice, especially in recent
years, is contact lenses. It wasn't so very long ago that patients were
told they could not wear contacts because of astigmatism, but that is no
longer the case. Advances in technology have allowed contacts to become
very effective in dealing with the condition and have also made them more
convenient than ever to wear.</p>
<p>Â Â Â Â Â Â Â Â Â Â Â Â Torics are <a rel="nofollow"

href="http://www.contactlensking.com/">contact lenses</a> designed to
correct for astigmatism. They contain two powers to address both the
blurriness incurred by the condition and related near- or
farsightedness. This dual purpose requires that the lens stays stable
upon the eye without rotating. Over the past 10 years manufacturers
have solved this by developing stabilizing techniques that keeps the
contacts in place, and therefore delivering the proper corrective powers
at all times. Torics now come in many modalities, from 30-day extended
wear on down to daily disposables. You even have the choice of colored
toric contacts that will enhance or change your natural eye color.</p>
<p>Â Â Â Â Â Â Â Â Â Â Â Â Your eye doctor can determine the degree of
astigmatism during your eye exam. From that point you can be prescribed
and fitted with the toric lenses that best suit your vision needs. The
eye doctor will also answer any questions or concerns you have. From
the point you are satisfactorily fitted with your contacts, you may
obtain a copy of your prescription in order to shop for replacement
lenses at any reputable venue of your choosing. Online sellers have
become very popular and provide a convenient way to shop, compare, and
buy your lenses from the comfort of home or office.</p>
<p>Â Â Â Â Â Â Â Â Â Â Â Â Astigmatism as a barrier to wearing contact
lenses is now a thing of the past. A call to your eye doctor is the
simple first step to get you on your way to taking advantage of the
convenience and fashion offered by contacts.    </p>        <!--
