If you suffer from astigmatism and are like most people, you have probably experienced the terror of a truly bad pair of toric contact lenses. Whether they stick to the eyes, dry out after a short period of time, cause redness and itchiness, or produce some other problem, they can be a cause of a great deal of frustration. If that describes you now or in the past, you may want to consider a brand called Air Optix For Astigmatism from CIBA Vision. They are daily or extended wear lenses designed to address many of the complaints experienced by users of other lenses, especially when worn for their maximum approved time of 6 continuous nights.
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.
The other factor, oxygen transmission, is equally important. Air Optix for Astigmatism lenses permit up to seven times more oxygen compared to some other contact lens brands, bringing a huge amount of much needed oxygen to your cornea. That ensures not just your cornea’s good health, but also contributes greatly to your lenses feeling comfortable.
Wearing comfort is great, but how does it address your blurry vision? Astigmatism is a condition where your cornea is shaped in such a way that it distorts light rays coming into the retina. That’s what causes you not to see properly. Air Optix for Astigmatism lenses sit on top of the cornea and act as a refractive filter through which rays of light must pass, which causes them to stop bouncing around and instead focus sharply on the retina where they belong. The result is a return to the crystal clear vision you seek.
Toric lenses must keep their stable position on the eye in order to work properly, and most brands do this by adding weight or ballast to the bottom of each lens. That works well enough, but it does occasionally cause your eyelid to bump against the bottom of the lens and this can cause a scratchy feeling eventually. Air Optix used a different design, something CIBA Vision calls a precision balance 8/4 design. It means that these lenses distribute the ballast weight evenly on the 8 and 4 o’clock positions on the lens rather than focusing it all on the bottom, which leads to a smoother lens and minimal bumping against your eyelids.
These lenses are also subjected to a patented plasma treatment that produces an extremely smooth surface that resists the buildup of lipids and proteins on the lens itself as you wear it throughout the day. This debris would otherwise add up and contribute to redness and irritation you do not want.
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.
Your eye doctor will advise you on the frequency of the replacement schedule for these lenses, which usually vary from weekly to monthly. It is important to follow his or her advice especially with regards to extended wear. While many people can use them for the prescribed 6 nights of continuous wear, some people cannot tolerate wearing lenses for lengthy periods and could do more harm than good. Only your doctor can tell you whether you can wear them in that fashion, or should limit yourself to daily wear.
Whether you seek consistently clear vision, better comfort, or less dryness, Air Optix For Astigmatism toric contact lenses have something for just about anyone. Stop suffering the dryness, itchiness, scratchiness and other symptoms you may be experiencing with other lenses. Instead, check with your doctor and try these lenses out for yourself. You’ll love the difference.
