Have you ever wondered about contact lenses as an option to correct your astigmatism? Ordinarily, the cornea is round, but the cornea of someone with astigmatism is more oval-shaped, sort of like a football. This alters the way light enters the eye, and as a result, vision is blurry.
Contact lenses that fix astigmatism, which are called toric contact lenses, are constructed from the same material as regular spherical contact lenses. The biggest difference between these and regular contact lenses is the design. Compared to regular 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. They feature curvatures at different angles. Because of their multiple powers, toric lenses need to stay in place on your eye. This is not the case with normal lenses, which can shift slightly without affecting your sight. However, lenses for astigmatism are smartly designed with this in mind, and they are a little heavier at the bottom, which helps them stay in place.
There are several scheduling options for toric contact lens users, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And people with astigmatism need not worry about options; toric lenses also come in color, or as multifocals. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher material that remains in form even when you rub your eyes or blink, and might give even better vision than soft lenses. But the downside is that they are often not as 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. Still, with constant improvements in eyewear technology, those with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
