Toric Contact Lenses - To Correct Your Astigmatism

Toric contact lenses have been a revolutionary product for many people who have found themselves in need of astigmatism correction.

For these individuals the chance to toss away those frustrating eyeglasses and experience the freedom of contact lenses has been a dream come true.

In the past contact lenses were created with an inner and outer layer that produced two separate surfaces. These surfaces were designed to have a spherical shape to fit the normal convex shape of the eyeball.

While this worked well in many instances the design did not work for people with astigmatism because they have irregularly shaped eyes that are more cylindrical in nature than spherical.

In fact many of those who tried normal contact lenses developed irritated eyes. Others had blurred vision, worsening of their regular vision and even dry eyes. There were also many occasions where the contacts would dislodge from the eye surface due to a poorly sealed fit, and they would then become lost.

How They Work

With a pair of toric contacts the design is cylindrical, much like the shape of the eyes seen in people diagnosed with astigmatism. With this newly engineered kind of lens there is a great deal more flexibility.

As a result the contacts can adapt to the eye shape of each individual wearer.

To further help the user there are some toric contact lenses available that have markings to indicate which edge is the Top and which edge is the Bottom. This subtle reminder can only be seen on the contact lenses before they are inserted in the eye, and can not be noticed while they are being worn.

A number of people with astigmatism only have the problem in one eye. If this is the case then it is easy to fit them one regular contact lens and a toric contact. In this case the main thing to remember is to make sure that they are inserting the right contact lens in each eye.

Customized Toric Lenses

If you suffer from astigmatism, or a related problem, you may even wish to choose specially fitted, customized contact lenses that are created just to fit the shape of your eyes and your individual vision prescription needs.

There are different specialty categories for these types of contacts ranging from a fairly standard model to very sophisticated and highly personalized lenses even suitable for people with high amounts of astigmatism.

Examples of customized toric lenses:

• Hydrasoft Toric Options
  These customized eyewear solutions are expensive but they are only replaced every 3 months which means you get a lot of wear out of them.

  Methafilcon B is a main component of these lenses and during the cleaning process this material attracts moisture and absorbs water. This results in lenses that feel smooth and soft to your eyes at all times.

• DuraSoft 2 Optifit Toric
  These toric lenses offer a precise fit and need replacement only once a year.

Extended Wear Toric Contacts

There are now several different options available if you should decide to choose toric contact lenses for your vision needs. You may even be able to select some of the lenses that are designed for extended wear up to 1 week at a time.

Toric lenses to be worn for up to 7 days:

• Air Optix for Astigmatism
  
  
• Acuvue Oasys for Astigmatism
  
  
• Biofinity Toric

Toric lenses to be worn for up to 30 days:
