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.
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.
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.
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 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.
