Have you ever wondered about contact lenses as a method of correcting your astigmatism? Firstly, what’s astigmatism, anyway? An eye with astigmatism has an irregularly shaped cornea (it’s shaped like a football, unlike a normal cornea, which is round), which changes how light enters the eye. The light doesn’t hit the retina properly, which drastically changes one’s ability to see clearly.
The lenses prescribed to correct astigmatism are called toric contact lenses. What separates these from regular lenses is the design. Consider them almost like the bifocals of contact lenses; they have a power to fix your distance vision issues and another for your astigmatism. They are designed with curvatures at various angles. Compared with regular lenses, which can easily move around on your eye and have no effect on your vision, toric lenses need to stay in place. A smart feature of astigmatism-correcting lenses is the fact that they’re weighted at the bottom, which helps them stay in place when you blink.
Toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And folks with astigmatism have no shortage of options; toric lenses also come in color, or as multifocals. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher substance that remains in shape even when you rub your eyes or blink, and might give better vision than soft lenses. But the downside is that they are often not as comfortable to wear. Together, we can find the best brand to suit your eyes.
Because toric lenses are just a bit more complex, expect the fitting to take a little more time. Nevertheless, with constant improvements in eye care, individuals with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
