Toric Contact Lenses: A Great Way To Correct Astigmatism

Have you considered contact lenses as a method of correcting your astigmatism? A regular cornea is round, but the cornea of an eye with astigmatism is more elliptical. This alters the way light hits the retina, and as a result, vision is out of focus.

Contact lenses designed to correct astigmatism, known as toric contact lenses, are manufactured from exactly the same material as regular lenses. What separates these from common contact lenses is the design. Compared to typical lenses, which have the same power throughout the lens, toric lenses have two different powers; one for astigmatism, and one to fix trouble with distance vision. They are designed with curvatures at various angles. Because of their multiple powers, toric lenses must stay in place on your eye. This is not the case with regular lenses, which can shift slightly without affecting your sight. Contact lenses for astigmatism are actually weighted on the bottom, and this prevents them from moving around on your eye.

Just like regular lenses, toric lenses are available as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you are used to multifocal or even colored lenses, there are toric lenses made to suit your needs too. Hard contact lenses, also called rigid gas permeable lenses, have a firmer shape which allows them to stay put when you blink, but they aren't always as comfortable as soft lenses. Together, we can find the best brand to suit your eyes.

Toric contact lens fittings can often need more time than the regular lens fittings you might be accustomed to, because of the relative complexity of the lens. But it's worth it. With advances in eyewear technology, individuals with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
