If you wear toric contact lenses but frequently experience itchiness, dryness, or general discomfort, you may benefit from using a contact lens with a more regular replacement schedule. One such brand is Vertex Toric contact lenses from CooperVision, which usually require replacement every week or two. They are intended for daily wear and removal, although some people can use them for extended continuous wear of up to seven days before replacement.
A high moisture level is a key factor for maximum wearing comfort. Vertex Toric lenses are made of methafilcon A, a water-retaining substance that allows the lens to absorb up to 55% of itself in water. This consistently high moisture level is key in making the lenses feel smooth and comfortable for as long as you are wearing them.
Toric lenses like Vertex Toric are specially crafted to combat astigmatism, which is a condition where your cornea is shaped oddly more like an egg than a perfect soccer ball shape. The unfortunate result of this is that light rays become distorted and jump around instead of focusing correctly on the retina, causing you the blurred vision to which you are accustomed without eye contacts or glasses. Vertex Toric lenses cure the astigmatism by sitting atop the cornea and refracting those light rays back into the retina where they belong, sharpening their focus and returning you to perfect vision.
Another thing that makes Vertex Toric lenses particularly easy to wear is the way in which they are made. They are manufactured using a patented technology called UltraSync, a process that produces a perfect edge on each lens. This leads to excellent stability, less rotation, and consistently outstanding comfort with each new pair.
Ease of handling is also another factor to consider when purchasing your lenses. CooperVision injects a slightly blue tint into the manufacturing process that is totally invisible when you wear the lenses, but which allow you to easily manipulate the lenses when removing, adding, or cleaning them. It also helps you find a lens if you drop it.
Vertex Toric lenses require frequent replacement, and only your eye doctor can determine the best replacement schedule for you. It will typically be 1 to 2 weeks between replacements for this brand. It is also essential to consult with him or her if you are considering using these lenses for overnight and extended wear of any length, because not everyone can tolerate this kind of wearing schedule. People have different medical needs, and what works for someone else might not work for you. Only your doctor knows for sure whether you can use these lenses for extended wear without other negative effects.
In short, Vertex Toric contact lenses are for individuals seeking flexibility in their wearing schedule along with a relatively brief replacement period. Flexibility is good for a busy lifestyle, while a short replacement regimen may help you if you have dryness issues with your current eye contacts. Ask your eye doctor about these lenses and see for yourself whether they are the answer you’ve been looking for.
