Air Optix For Astigmatism Toric Contact Lenses Feature Outstanding Wearing Comfort
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.
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.
As an added bonus, these lenses feature a plasma surface treatment to produce a super-smooth surface designed to resist the buildup of deposits that tend to accrue throughout the day. These include proteins and lipids from your tears that if left unaddressed can lead to itchiness and discomfort.
Air Optix for Astigmatism lenses are also constructed for ease of use and handling. They feature three scribe marks at the 3, 6 and 9 o’clock positions to guide you when correctly inserting the lens, which is important for treating astigmatism. The lenses are also treated with a slightly blue dye that is invisible when worn but assists you when inserting, manipulating or cleaning the lenses.
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 have something good for you. If you’ve been suffering from wearing other contact lenses and are tired of the itchiness and scratchy eyes, ask your doctor about this brand and experience the difference for yourself.
