Toric Lenses Best For Correcting Astigmatism 1 Powered By Docstoc
					Astigmatism is condition where the patient experiences blurred vision due
to the distortion of cornea. It causes the light rays to fall on the
retina from a number of different angles, which makes the eye lose focus.
The condition can be corrected by wearing Toric Lens.       Well, toric
lens is not much different from an ordinary contact lens so far as the
material it is made of is concerned. It is different in that its one or
both sides of the optical surface work as a cylindrical lens often
combining it with spherical lens effects. It may happen sometimes that
only one eye has astigmatism while the other is perfectly alright. In
such cases the patients are advised to wear a Toric lens in one eye and a
normal vision correction lens in the other.


  Toric lenses, though made of the same material as the ordinary contact
lenses, are effective in correcting both the cylindrical as well as
spherical aberrations. Being asymmetrical around the center, they should
not be rotated. They are designed to remain unaffected by the movement of
the eyes.      Toric lenses need to be custom fitted to suit your eyes
and so they take a little longer to be checked and re-checked to make
sure that your vision is effectively corrected by the lenses and that
they fit you properly. It is then that you can leave the specialist's
clinic and go home with your lenses.      It is not necessary that only
Toric lenses can correct astigmatism. If it happens to be of a lesser
degree a normal lens can effectively mask it. However, a higher degree of
astigmatism can only be corrected by a soft toric lens, rigid contacts or
spectacles. One may go for either a soft or rigid contacts. Soft lenses
have an edge over the rigid ones in terms of comfort and adaptability
while the rigid lenses score better than soft lenses in durability.
Besides, rigid lenses are also a little easier to take care of than the
soft ones. Many users also feel that rigid lenses give a crispier vision
compared to the soft lenses.      Another option that is sometimes
explored is the gas permeable lenses. They do not have any ability to
correct astigmatism but their inflexibility makes them reshape the eyes.
This helps correct the vision in cases of mild astigmatism. However, for
higher degree of astigmatism Toric lenses seem to be the best available
option.      To read more articles on contact lenses, buying contact
