Astigmatism is a common vision problem. The cause of an astigmatism is a cornea or lens that is irregular in shape--usually the cornea. An astigmatism may be accompanied by near-sightedness or far-sightedness. You may not even know you have this condition as it may do little more than make things slightly blurry. It makes a big difference, however, in the type of contacts you use if you want colored ones.
Background
At one time, those with an astigmatism could not wear contact lenses at all. As contact lenses continued to evolve, options increased. There are now toric lenses for astigmatism that are available in many types, including multifocal, disposable and color. The difference between toric color contacts and regular ones is that all toric lenses have two powers in them -- one to correct the astigmatism and one for the vision.
Hard or Soft
Contact lenses are made of plastic material. The most common hard lenses are referred to as RGP because they are rigid and gas permeable. They are durable and have a longer life span than soft contact lenses. Soft contact lenses are thinner and made of plastic that absorbs water. They are considered more comfortable. Some people prefer hard lenses, though, because they retain shape, providing a little clearer vision.
Availability
If you have an astigmatism, you can buy toric lenses to either enhance or completely change your current eye color. They can be purchased online (1800Contacts and VisionDirect are two sites with a large selection) or through your eye care professional. Color contacts for astigmatism are available in daily and long term, with a wide assortment of colors. Some of the brands include FreshLook Colorblend Toric by CibaVision and DuraSoft3 Optifit Toric Colorblends.
Considerations
Color contact lenses for astigmatism take longer to fit than non-toric lenses, and proper fitting is very important so the lens covers the eye and the colored part does not move around. They are also more expensive. If your astigmatism is not severe (between zero and +1.00 or -1.00), you may be able to wear colored contact lenses that are not torics. Check with the eye care specialist who fits your lenses.
Warning
All contact lenses should be used under the care of a doctor. You should not use contact lenses that haven't been prescribed by an optometrist or ophthalmologist who has fitted you for the lenses. Ill-fitting contact lenses can impair your vision. Never use someone else's contact lenses. Be sure to keep your color contacts for astigmatism clean with disinfecting solution so you do not get an infection.
