Whether you’re going green and hate the idea of frequently disposable lenses, or just don’t want to be bothered with replacing your toric contact lenses for astigmatism every day/week/month, check out Preference Toric lenses from CooperVision. These lenses feature a planned quarterly replacement schedule, so that you only have to throw them out for new ones four times a year. They are intended for daily wear and cleaning.
Any lenses slated for replacement four times a year must be extremely durable in order to withstand the daily wear and tear. Preference Toric lenses meet this challenge by being made of a polymer called tetrafilcon A, a sturdy substance that will enable your lenses to last the entire time.
Tetrafilcon A is also deposit-resistant, another important feature for a lens of such long duration. As the days and weeks go by, lenses tend to accumulate protein deposits and other detritus produced from tears. This buildup will eventually cause discomfort, dryness, and could ultimately lead to further problems or infection. By resisting this buildup of deposits, Preference Toric lenses promote a greater comfort level as well as healthier, moister eyes.
Ease of use is an important consideration, and these lenses are very easy to handle. CooperVision adds just a hint of blue tint to the lenses. While invisible when worn, this blue tint will help you see your lenses when you remove, clean, or accidentally drop them.
When you have astigmatism, your cornea is shaped like an oval or egg rather than a sphere, which distorts your vision and scatters light rays rather than focusing those rays on the retina. Lenses like Preference Toric reverse the condition by acting as a refractive prism that compensates for the cornea’s odd shape and restores perfect visual acuity.
You should use Preference Toric lenses on their quarterly replacement schedule only on the guidance of your eye doctor. While the lenses are constructed to last for three months, your individual physiology may dictate that you use them for less time since every person’s medical needs are different. To do otherwise is to risk infection and other problems with your lenses, so please do work closely with your vision care provider.
With Preference Toric contact lenses you do not have to sacrifice wearing comfort, ease of use, or the environment when in pursuit of the best convenience. Nothing could be easier than replace-and-forget a mere four times per year. You do have to remove and clean them daily, but that’s a small price to pay for an otherwise amazingly convenient product. So forget about the replacement calendar, get yourself a set of these lenses, and enjoy!
