A Closer Look at Astigmatism and Contact Lenses

A lot of people with astigmatism are under the impression that they can't use contact lenses due to their condition. Well, there's actually a special sort of contact lens made just to correct astigmatism. The cornea is normally spherical, but when you have astigmatism, it's more elliptical. This alters the way light hits the retina, and as a result, vision is blurry.

The lenses used to correct astigmatism are known as toric contact lenses. What separates these from regular contact lenses is the design. As opposed to regular lenses, which have one power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one to fix myopia or hyperopia. 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 actually ballasted on the bottom, and this helps them stay in place on your eye.

There are a number of scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you prefer colored or multifocal contact lenses, then don't worry, there are toric lenses for you. Hard contact lenses, also called rigid gas permeable lenses, have a stronger shape which helps them stay in place, but they aren't always as comfortable as soft lenses. .

Because toric lenses are a little more complex, you should factor in some extra time for your fitting. It might sound a little daunting, but it's well worth the end result; effective, glasses-free treatment. Getting the best product for you will only improve your vision, and thus your quality of life.
