Toric Lens Information
A Toric Lens
is a special type of contact lens that is used for people with astigmatism, which is an eye condition that doesn't allow the use of a normal contact lens for vision correction.
Astigmatism is where the eye is unable to fully form a sharp image inside the Retina. As a result, you have Blurry Vision constantly, even with the use of
Because of this, normal Contact Lenses will provide absolutely no benefit to a person with an Eye Astigmatism.
Astigmatism comes in two different forms, known as Regular Astigmatism and Irregular Astigmatism.
The irregular variety is usually the result of a scar on the Cornea of a random scattering of the lens. This type can actually be helped somewhat by a regular pair of Contacts. Regular astigmatism, on the other hand, requires the use of Toric Lenses for Astigmatism because the eye actually looks like a football where the sections of radii come together.
So now that you know what astigmatism is, let's take a look at the actual toric lens itself. They are made from the exact same material as a regular Contact Lens, but they differ because the design and curvature is radically altered.
Unlike normal lenses, toric lenses are manufactured with two different powers, also known as prescription strengths. They intersect at a specific angle so that one power deals with the astigmatism itself while the other power addresses either Myopia also known as nearsightedness or short sightedness or
Hyperopia also known as farsightedness or long sightedness.
The other difference is that a toric lens absolutely cannot rotate around in the eye. It must be kept at a very specific angle to provide benefit. As such there is a tiny mechanism in the lens that stops any rotation while it is being worn. This stability is accomplished by making the lens slightly heavier at the bottom, which keeps it from spinning, as the heavier side always wants to stay at the bottom.
Since there is a lot more expertise required to manufacture a this lens, they typically cost more than regular contacts. The fact that they are specialized for one certain condition doesn't help the price out much either. Additionally, the process for discerning the proper prescription strength requires a specialized Eye Care Specialist or Eye Care Professional with the right field of knowledge, and that tends to be more expensive too. Cost aside, they are a fantastic invention that finally gives people with astigmatism hope of leading a normal life.
If you only have mild astigmatism, you probably won't need a this lens. To Protect Your Eyesight it's extremely important to keep your eyes filled with the essential Vitamins and Minerals. Vitamins C, A, and E are required by the eyes to maintain their proper function, so even if you have astigmatism you can still ensure that you have Healthy Eyes.
