A Closer Look at Astigmatism and Contact Lenses

Are you aware that there are contact lenses especially for people with astigmatism? To begin, what's astigmatism, anyway? Astigmatism means that your eye has an irregularly shaped cornea, which means that light entering your eye through the cornea can't come to a single focal point on the retina, resulting in blurred vision.

Contact lenses designed to fix astigmatism, known as toric contact lenses, are manufactured from the same material as regular spherical contact lenses. What differs between these and common lenses is the design. Compared to typical lenses, which have the same power throughout the lens, toric lenses have two different powers; one for astigmatism, and one for trouble with distance vision. Unlike regular lenses, which can freely move around on your eye and have no effect on your vision, toric lenses must stay in place. Contact lenses for astigmatism are therefore ballasted on the bottom, and this prevents them from moving around on your eye.

Toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you prefer multifocal or even colored lenses, then don't worry, there are toric lenses made to suit your needs too. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher material that remains in form when you blink, and might provide sharper vision than other lenses. However, they are usually less comfortable to wear. Together, we'll be able to find the most suitable brand for your eyes.

When it's time for your toric lens fitting, it's going to take some time, due to the complexity of the product. This all might seem like a bit of effort, but it's well worth the end result; getting treated, glasses-free. Getting the right product will only improve your vision, and consequently, your everyday life.
