Toric Lenses: A Life Changer for Astigmatism

So many people with astigmatism think they are not able to use contact lenses due to their condition. It may come as a surprise to know that there's actually a special kind of contact lens made just to correct astigmatism. The cornea of a normally sighted person is spherical, but in the case of someone with astigmatism, it's more oval-shaped, sort of like a football. This ostensibly minor feature actually changes the way light hits the retina, and as a result, vision is blurry.

Toric contact lenses are used to fix this condition. What separates these from common contact lenses is the design. Compared to typical lenses, which have one power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one for trouble with distance vision. They have curvatures at different angles. Due to their particular design, toric lenses need to remain in place on your eye in order to correct your vision, unlike spherical contact lenses, which have no effect if they rotate on your eye when you blink. However, lenses for astigmatism are smartly designed with this issue in mind, and they are weighted slightly at the bottom, which helps them stay in place.

Just like regular lenses, toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you are used to multifocal or even colored contact lenses, there are toric lenses for you. Hard contact lenses, also called rigid gas permeable lenses, provide a firmer shape which helps them stay in place, but they aren't always as comfortable as soft lenses. Together, we can find the best brand to suit 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. But it's worth it. With advances in eyewear technology, those with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
