A lot of people with astigmatism are under the impression that they are not able to use contact lenses due to their condition. Well, there's actually a special kind of contact lens made just to correct astigmatism. An eye with astigmatism has a differently shaped cornea, and that means that light entering your eye through the cornea isn't able to 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 made from exactly the same material as regular spherical contact lenses. What differs between toric lenses and regular lenses is the design. Compared to regular lenses, which have the same power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one to fix trouble with distance vision. They have curvatures at different angles. In contrast to regular lenses, which can easily move around on your eye and have no effect on your vision, toric lenses need to stay in place. But lenses for astigmatism are smartly designed with this in mind, and they are weighted slightly at the bottom, which helps them stay in place.
Just like regular lenses, toric lenses are available as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. Toric lenses are also available as color contact lenses, and as multifocal lenses. Hard contact lenses are made from a tougher substance that remains in form even when you rub your eyes or blink, and might give even better vision than other lenses. However, they are usually less comfortable to wear. Together, we can find the most suitable lens type for your eyes.
Toric lens fittings often take longer than normal lens fittings. This is because it's a more complex product, and we want to make sure that you leave with a pair that fits you perfectly. Still, with constant growth in eyewear technology, those with astigmatism have lots of life-improving options to choose from.
