Are you tired of toric contact lenses for astigmatism that stick to your eyes, cause you terrible itchiness and redness, or are just plain bad? If so, you may want to consider Air Optix For Astigmatism lenses from CIBA Vision. Approved by the US Food and Drug Administration for either daily wear or extended continuous wear of up to six nights, these lenses are specifically designed to address the problems encountered by so many contact lens users.
When considering wearing comfort, look to a lens’s ability to transmit oxygen and ability to retain moisture. These two factors, more than any other, will determine how good a lens feels in the eye. As far as moisture is concerned, Air Optix lenses are made of lotrafilcon B, a substance that absorbs water and resists its eventual dehydration while the lens is being worn.
Air Optix for Astigmatism lenses also feature a high amount of oxygen transmission to the cornea, up to seven times as much as some other brands. That is essential not just for your wearing comfort but also for your cornea’s health. This is especially true for any lens that is usable for extended wear, since the eye’s need for oxygen must be well-met for that entire time.
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.
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.
Ease of use and handling for these lenses are a snap. The lenses are tinted ever so slightly with a blue dye that is invisible while wearing the lenses but that allows you to find and manipulate the lenses when cleaning, storing, or inserting them. Three scribe marks at the 3, 6 and 9 o’clock positions make it easy to place the lens properly on the eye, which is especially important for astigmatism.
The replacement schedule for these lenses is flexible, and can range from weekly to monthly based on your eye doctor’s recommendation. It’s important to consult with him or her, especially if considering these lenses for extended wear. While many people can use them for the full six nights, other people have differing levels of tolerance of such long periods of continuous wear. Depending on your individual eye needs you may not be in fact eligible for extended wear but only your eye care practitioner can tell you for sure.
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.
