Toric Contact Lenses - for People with Astigmatism!
It used to be that people with astigmatism had to settle for eyeglasses because contact lenses could not provide the needed correction for the slight malformation of the eyeball, lens or cornea. In astigmatism, because of the slight imperfection in the shape of the eye, the light rays cannot be focused on the retina so that a person suffering from this condition has cloudy or blurred vision. When contact lenses were introduced, they could only correct nearsightedness or farsightedness because it was difficult to prevent the contact lenses from moving if the wearer blinked or shifted his or her eyes. To correctastigmatism, the contact lenses should be aligned perfectly and should not move and this was impossible with contact lenses.
Toric Contact Lenses Have Arrived
But that was before the development of toric contact lenses. These special contact lenses are shaped in such a way to provide correction for astigmatism. They are also provided with a mechanism to ensure that movement is minimal when the person shifts the eyes or blinks. One way to do this is to make the lower part of the lenses heavier or ballasted. This design allows the eyelids to push down the lenses into the proper position when the patient blinks. Toric contact lenses, just like the regular lenses, are either soft or Rigid Gas Permeable (RGP). Another important difference in this type of contact lenses is that they are much more difficult to fit and thus, you can expect your eye care specialist to charge a higher fee. Of course, the lenses themselves will cost more because of their special design.
