toric contact lens
Astigmatism is a quite common condition.
Many who have a slightly blurred vision don’t even
know that they have astigmatism and their vision can be
improved with toric contacts. More severe cases or astigmatism
are impossible to ignore, because the person sees everything
blurry at any distance.
Astigmatism is usually a hereditary condition and it doesn’t
progress. What happens is that in an astigmatic eye (cornea,
the lens or both) is irregularly shaped. It resembles a
football ball rather than a normal spherical shape.
There are two variation or astigmatism: regular and irregular.
In regular astigmatism, the meridians in which the two different
curves lie are located 180 degrees apart. In irregular astigmatism,
the two meridians may be located at something other than
180 degrees apart; or there are more than two meridians.
Regular astigmatism can be easily corrected with toric
contact lenses. Irregular astigmatism is more complicated
and difficult to correct. It usually required custom made
contact lenses.
Uncorrected astigmatism not only blurs your vision it can
also give you headaches and eyestrain. So even the slightest
condition shouldn’t be ignored.

Kids often develop astigmatism, but they are usually afraid
of a necessity to wear glasses, so they don’t complain
about their vision. Even though astigmatism doesn’t
progress, it can make a child’s life difficult at
school.
It is recommended to give your child a regular eye examination,
at least once a year. And if he or she is diagnosed with
astigmatism, your child doesn’t have to wear glasses.
Modern toric lenses are very good for correcting astigmatism,
and they are absolutely safe for kids. In fact even babies
can wear contact lenses, of course the parents will have
to insert and remove the contacts.
Many people believe that if they have astigmatism, they
are staked with RGP contact lenses. This is no longer true.
Recently developed soft
toric contact lenses can do as good job in correcting
astigmatism as Rigid Gas Permeable contacts.
