					Toric contact lenses are designed to help correct astigmatism.
Astigmatism is caused by an irregularly shaped cornea which makes vision
blurry. It is a very common condition and most people have some form of
it, even if just very mildly.Astigmatism can be diagnosed by an
optometrist during an eye examination. He or she will also be able to
assess how severe it is and make recommendations to correct it.You might
want to consider getting a check up if you are experiencing blurred
vision, headaches and/or eyestrain. Having said this it is important for
all adults under the age of 65 to get their eyes checked on a regular
basis. We usually recommend that people with healthy eyes get them tested
at least once every two years.In the majority of instances it can be put
right by wearing either toric contact lenses or glasses. If it is mild
enough your optometrist might say that you do not need treatment unless
there are special circumstances, such as the fact that you work in front
of a computer all day.Toric contact lenses are very popular for
correcting astigmatism. Unlike ordinary lenses they have two different
prescriptions which are positioned at right angels to each other.
Furthermore, they have a special weighting built into them to make sure
that they stay in place when you move your eyes around.The reason that
toric contact lenses are used to correct astigmatism is that they alter
the curvature of your cornea thereby correcting the problem.With so many
different types of toric contact lenses available, you should speak to
your optometrist about the best option for your particular needs.Another
treatment option is to have refractive surgery. This is designed to alter
the shape of your cornea to correct the problem. This type of surgery is
done with the use of either lasers or implantable lenses.
