Do you suffer from astigmatism but struggle with toric contact lenses that are itchy or dry? Sometimes a more frequent replacement schedule can help. Vertex Toric contact lenses from CooperVision are typically worn from one to two weeks between replacements. They’re also usually for daily wear and removal, although some people can tolerate them for up to seven days of extended non-stop wear.
You can’t have comfortable lenses without a high moisture level in both the lenses and your eye. Vertex Toric lenses are made of methafilcon A, a water-loving polymer that absorbs water to the point that the lens is comprised of 55% water when fully moist. That high of a moisture content is great news for your eyes, because it helps to keep the lens feeling soft and silky all day long.
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.
The way in which the lenses are made also factor in how comfortable they feel in your eyes and how well they function as toric lenses. Vertex Toric lenses are made of a patented process called UltraSync, which creates a perfectly smooth edge on every lens. This perfect edge maximizes your wearing comfort along with providing much-needed stability and protection from excessive rotation while the lenses are worn.
These eye contacts are also very easy to manipulate. They are made with a very light blue tint that allows you to see and handle them clearly when not being worn, yet the tint is totally invisible while the lenses are in your eye. That will save you a lot of time when handling the lenses or trying to find one you have dropped.
Vertex Toric lenses require frequent replacement, and only your eye doctor can determine the best replacement schedule for you. While they are usually prescribed for weekly or bi-weekly replacement, your eye doctor may disagree and prescribe you something different. Even more importantly, he or she may have something to say if you think you might want to use these lenses for extended non-stop wear. While many people can use the lenses on that basis, many others cannot because of medical needs unique to them. Don’t play a guessing game–ask your vision care provider about the best wearing and replacement schedule for you.
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.
