Are you tired of the hassle associated with remembering to replace your toric contact lenses for astigmatism every month, week or day? Or maybe you’re trying to be environmentally conscious and hate the waste associated with disposable lenses. Whatever the case may be, there’s a solution for you. Preference Toric contact lenses from CooperVision feature an amazingly low quarterly replacement schedule. That means you only have to throw them away and replace them four times per year!
As you can imagine, any contact lens intended for quarterly replacement must be extraordinarily sturdy. Three months of wear and tear is a long time. Preference Toric lenses are made up of a polymer called tetrafilcon A, a highly durable substance that will make your lenses last the entire three months.
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.
Another factor for any great set of lenses is how easy they are to use and handle. The manufacturer adds just a little bit of blue dye to the lenses during the manufacturing process. While this dye is invisible when the lenses are worn, it’s great for when you have to remove and clean them. It also helps a lot for when you accidentally drop one!
In case you are not aware, astigmatism is a condition where your cornea is shaped like a football instead of the more perfect sphere that most other people have. This odd oval shape distorts light rays and causes them to scatter everywhere except the retina where they should be. The result is blurry vision. Preference Toric lenses compensate for this problem by sitting on top of the cornea and properly refracting those rays of light so that they end up exactly where they belong. The end result you’ll love is crisp, clear vision as the astigmatism is overcome.
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!
