Did you know that there are contact lenses especially for people with astigmatism? The cornea is generally round, but the cornea of an eye with astigmatism is more oval-shaped, almost like a football. This affects the way light hits the retina, and as a result, vision is blurred.
Toric contact lenses are used to correct astigmatism. Toric lenses are constructed differently from regular lenses. Compared to ordinary lenses, which have the same power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one which addresses myopia or hyperopia. In contrast to regular lenses, which can freely move around on your eye and have no effect on your vision, toric lenses need to stay in place. A handy feature of astigmatism-correcting lenses is the fact that they're weighted at the bottom, which helps them stay in place when you blink or rub your eyes.
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, then don't worry, there are toric lenses for you. Hard contact lenses, also called rigid gas permeable lenses, are made from a material that gives them a firmer shape which helps them stay in place, but usually, they're a little less agreeable to wear than soft lenses. .
Toric contact lens fittings may often require more time than the regular lens fittings you might be accustomed to, because of the fact that these lenses are a little more complex. It might seem like a bit of effort, but it's worth the end result; getting treated, glasses-free. Being fitted with the best product for you will only improve your vision, and thus your everyday life.
