Contact Lenses
For Astigmatism
Astigmatism is a condition that causes blurred vision
near or far. Astigmatism can be combined with near or far
sightedness though, creating a compounded condition.
The most common type of astigmatism occurs when the cornea
isn't perfectly round and symmetrical. It's kind of warped
but with 2 separate and unequal curves.
Contact lenses for astigmatism are somewhat of a new thing
to the world of contacts. There are basically two types of
contact lenses for astigmatism. Soft contact lenses and hard
contact lenses to put it in simple terms. |
 |
The soft type of contact lenses
are often used for mild to medium astigmatism and hard
contact lenses are usually utilized for medium and more
severe cases. |
Soft contact lenses for
astigmatism vary in thickness to compensate for the
irregular shape of the eye. In severe cases soft contact
lenses don't usually work well for astigmatism. If the shape
of the eye is too distorted soft contact lenses will flex
which only worsens the problem.
Most often the more solid type of contact lenses are needed
for moderate to severe astigmatism. These lenses are shaped
perfectly inside and out. The wearers eye fluid will fill in
the air gap where the imperfections exist. This fluid acts
as part of the contact lens. Contact solution is used to
initially fill in the would be air gap for these sturdy type
contact lenses for astigmatism.

Some eye doctors believe contact
lenses actually work better for astigmatism than glasses.
Glasses for astigmatism can cause a kind of unequal
distortion. When a person with astigmatism looks through
their glasses at an angle there is more magnification in one
direction than another.
This condition doesn't occur with properly fitted contact
lenses for astigmatism. Contact lenses sit directly on the
cornea so there is no space between the lens and the eye.
This way there isn't the situation with more magnification
in one direction than another. |
|
Some doctors who haven't kept up with technology may even
tell patients that contacts for astigmatism don't exist.
This is actually not the case, either your doctor doesn't
want to deal with the extra work of properly fitting contact
lenses for astigmatism or they simply don't know how. If
this is your case you may want to seek an alternative
opinion. Talk with your friends and find an optometrist that
is experienced with fitting contact lenses for astigmatism. |
