If you suffer from astigmatism and have worn extended wear toric contact lenses in the past, you have probably experienced the dry itchiness and redness that seems almost inevitable with these types of lenses. If that describes you, you may want to take a look at Air Optix for Astigmatism lenses from CIBA Vision. Featuring the flexibility of either daily wear or continuous wear of up to six nights, these lenses are specifically designed to address the long-term wear issues that arise when you wear lenses for a longer period of time. Oxygen availability and moisture level are of paramount importance in determining the comfort level of an eye contact. In terms of moisture, Air Optix lenses are constructed of a polymer called lotrafilcon B, which is built to be super-absorbent and can hold up to 33% water. This material can also maintain steady moisture levels by resisting the rate of dehydration as the day goes on. If you consider oxygen transmission, Air Optix for Astigmatism lenses provide up to seven times as much of it as certain other brands. Your eye needs all the oxygen it can get, so increased permeability not only encourages your eye's good health but also maximizes your wearing comfort for as long as you use the lenses. While wearing comfort is important, so is the ability to actually address your blurry vision. Astigmatism occurs when the eye is shaped oddly, more like an oval than a sphere, which distorts rays of light as they enter the retina and causes the bad vision you suffer. Air Optix for Astigmatism lenses reverse the problem by sitting atop the cornea and acting as a prism that compensates for the eye's shape and restores you to crisp, clear visual acuity. Most toric lenses are designed to be heavy on the bottom to keep them properly balanced on the eye, but this has the unfortunate side effect of occasionally rubbing against your eyelid when you blink. CIBA Vision attacked this problem by distributing the greater weight to the 4 and 8 o'clock positions on the lens through what it calls a precision balance 8/4 design. This prevents your eyelids from bumping the lens and causing scratchy eyes. These lenses have the added bonus of being subjected to a patented plasma treatment intended to deliver a super-smooth surface on each lens that actually repels debris and prevents it from building up. This debris includes lipids and proteins that would otherwise start accumulating while you wear the lenses and would eventually lead to irritation and sore eyes. Air Optix for Astigmatism lenses are very easy to use and handle. They are tinted slightly with a blue compound that lets you find, manipulate, and clean the lenses without ever interfering with your vision. They also come with three scribe marks on the 3, 6 and 9 o'clock position to advise you on how to correctly place the lens on your eye, which is important when treating your astigmatism. While many people can wear these lenses for their approved six nights of extended wear, you may be one of the unlucky ones that can't wear contact lenses for such a long time. That's why it is essential to talk with your eye doctor and get his or her feedback about whether these lenses are good for you and for how long you can wear them. Your doctor will also recommend a replacement schedule, usually varying anywhere from a week to a month between replacements. Whether you seek consistently clear vision, better comfort, or less dryness, Air Optix For Astigmatism toric contact lenses are likely to be a brand you will love. Why put up with redness, discomfort, and other problems when you don't have to? Ask your doctor about these lenses and try them out for yourself.
