Toric Contacts
Toric Contact Lenses
Toric contact lenses are specifically designed to provide vision correction to those individuals with astigmatism. In the past, toric contacts didn't exist, leaving these individuals with no choice but to wear eyeglasses to correct their vision. Today, a multitude of choices exist for those needed toric contacts, including disposable toric contacts, colored toric lenses, and even multifocal toric contacts.
About Toric Contacts
Toric contacts are manufactured just like other lenses and are
available as both soft lenses and rigid
gas permeable lenses. Toric
contacts differ from others in the lens design. Toric lenses are
manufactured with two different curvatures that address both
astigmatism and hyperopia or myopia.
Toric contacts are manufactured to address the vision needs of those
with astigmatism.
About Astigmatism
Astigmatism refers to an imperfection in the curvature of the eye.
This imperfection results in blurred vision, but is easily
treatable. The imperfection can rest with either the cornea or the
lens, causing a different curvature in one direction than the other.
For this reason, two types of astigmatism exist; corneal astigmatism
and lenticular astigmatism. Unlike a normal eye, the eye surface is
not smooth in every direction but instead has areas that are steeper
or flatter than others.
Astigmatism is a condition that is usually present from the day your
born. Most people have some degree of astigmatism, but only those
whose condition causes blurred vision require toric contacts or
special eyeglasses to address their vision needs.
Treatment for astigmatism includes
corrective lenses, in the form of
eyeglasses or toric contacts, or surgery.
Toric contacts address the limitations caused by astigmatism by
making the surface of the eye consistent. Toric contacts can address
both lenticular and corneal astigmatism and have become the number
one choice for treating astigmatism.
The National Institutes of Health offers detailed information about
astigmatism and toric contacts.
