Are you thinking of going green and just hate the idea of throwing away your toric contact lenses for astigmatism every day, week, or month? Or maybe you just can’t be bothered by the hassle of remembering to change your toric lenses on such a frequent schedule. Whatever the reason may be, if you want contact lenses that require a minimum of hassle you should definitely check out Preference Toric lenses from CooperVision. Featuring an amazing quarterly replacement schedule, you only have to think about throwing away and replacing these lenses four times a 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 has other nice properties. Among them, it is highly deposit-resistant. As time goes on, lenses tend accumulate protein deposits and other detritus from your tear fluids. Left unchecked, this buildup of deposits can cause dryness and possibly an eye infection. That’s not good. By being resistant to this buildup, then, these lenses help ensure that they end up feeling smooth for a good long time. It also helps ensure good health for your 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.
It should go without saying that you must consult your eye doctor before using these lenses to make sure they work for you. It’s also important to get his or her feedback to make sure that your eyes can tolerate the quarterly replacement schedule. Your vision needs are unique to you, and while the lenses are constructed for quarterly replacement your eyes may be more sensitive than most and may not be able to handle that. In such a case your doctor would suggest a different replacement schedule.
With Preference Toric contact lenses you do not have to sacrifice wearing comfort, ease of use, or the environment for convenience. Forget about weekly or monthly replacement hassles and just worry about changing your lenses four times a year. In the meantime, enjoy the fresh smooth feeling and wearing comfort these lenses offer. The environment will also thank you for throwing fewer lenses away!
