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.
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.
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.
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 summary, Vertex Toric contact lenses offer a combination of a flexible wearing schedule with frequent replacement. The wearing schedule is a lifestyle choice, while the frequent replacement may help you if you frequently suffer from dry or itchy eyes while wearing eye contacts. Ask your doctor about Vertex Toric lenses and see what a big difference they can make for you.
