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 unique type of contact lens that corrects astigmatism. The cornea of a normally sighted person is round, but the cornea of an eye with astigmatism is more elliptical. This seemingly small feature actually alters how light hits the retina, and results in blurred vision.
The lenses eye doctors use to correct astigmatism are known as toric contact lenses. The main difference between toric lenses and regular lenses is the design. Think of them as almost like the bifocals of contact lenses; they have a power to fix your near or far sightedness and another for your astigmatism. They are designed with curvatures at different angles. In contrast to regular lenses, which can freely shift and have no effect on your vision, toric lenses must stay in place. Contact lenses for astigmatism are therefore weighted on the bottom, and this prevents them from moving around on your eye.
There are multiple scheduling options for toric contact lens wearers, including 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, also called rigid gas permeable lenses, have a firmer shape which allows them to stay put when you blink, but usually, they’re a little less agreeable to wear than soft lenses. Together, we can find the most suitable lens type for your eyes.
Due to the fact that toric lenses are a little more complex, expect the fitting to take a little more time. It might seem like a bit of effort, but it’s worth the end result; effective, glasses-free treatment. Being fitted with the right product will only improve your vision, and consequently, your quality of life.
