Contact lenses for astigmatism has proven to be hugely sucessful and a great boost to astigmatism sufferers

Astigmatism for ages was an eye problem that might not be completely corrected with contact lenses. Mild astigmatism might be adequately improved with soft contact lenses, but there were not options for more serious cases. The eye problem itself results from a misshaped cornea - instead of being round like a ball, the cornea in folk with astigmatism is oblong.

Due to this shape, light rays can't refract correctly against the retina. Rather than targeting the rays on one spot, the peculiar shape causes light to refract in multiple locations on the retina, causing the blurred vision, in any case of distance, that is symptomatic of astigmatism.

The development of toric contact lenses for astigmatism opened up a brand new arena of vision for folks with astigmatism. Toric contact lenses do not look any different than other soft or stiff gas permeable contact lenses, but basically they are totally different.

The lenses consist of a few different curvatures in varied meridians or sections on the lens. Since astigmatism is an issue involving unbalanced meridian sections ( thanks to the wierd shape of the cornea ) bringing the meridian sections into balance is what helps produce clear vision.

Since the positioning of the diverse curvatures is prime to improving vision, toric soft contact lenses can't revolve - they must be held in a certain position to be effective.

One way is to add weight to the base of the lens by building up or thickening that section. An alternative way is to make the top part of the lens lighter, by thinning this section. One more way to fix astigmatism with contact lenses is to use firm gas permeable lenses.

These contact lenses for astigmatism are no longer as delicate as soft lenses and that enables them to keep hold of their shapes, even after blinking. Regular gas permeable lenses work effectively at correcting mild to moderate astigmatism, but in cases where the astigmatism is serious, it's often important to purchase gas permeable toric contact lenses.

Toric lenses are custom formed so that the interior of the lens more closely matches the form of the astigmatism. Due to the customised fit, toric lenses remain in position and revolution isn't a problem. And because toric contact lenses involve customization, you will likely have to pay more for this kind of contact lens.

You may even find that your eye doctor charges more when fitting you for toric lenses thanks to the additional work concerned in properly measuring each eye.

If you work with an eye doctor you trust, she or he will probably first try and prescribe regular contact lenses to treat your astigmatism.

Again, mild and moderate astigmatism can usually be adequately corrected with standard lenses. Only when the astigmatism becomes serious is it important to resort to toric style contact lenses. When this occurs, you'll be able to find contact lenses for astigmatism in toric lenses are available as regular wear, extended wear, silicone hydrogel and disposable brands.

Color Contacts for astigmatism come in a collection of eye color options. Astigmatism with contact lenses, the options are there.
