Lots of people with astigmatism are under the impression that they can’t wear contact lenses. It may come as a surprise to know that there’s actually a unique sort of contact lens that corrects astigmatism. A regular cornea is round, but when you have astigmatism, it’s more oval-shaped, sort of like a football. This seemingly minor feature actually affects the way light hits the retina, and results in blurred vision.
The lenses eye doctors use to correct astigmatism are known as toric contact lenses. Toric lenses have a design that differs from that of regular lenses. Regular lenses have one power, but toric lenses have two: one for myopia or hyperopia and one for astigmatism. Compared with regular lenses, which can easily shift and have no effect on your vision, toric lenses must stay in place. Toric lenses are therefore weighted on the bottom, and this helps them stay in place on your eye.
There are multiple scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you like to wear colored or multifocal contact lenses, then don’t worry, there are toric lenses for you. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher substance that remains in shape even when you rub your eyes or blink, and might provide even better vision than other lenses. But they are usually less comfortable to wear. Together, we’ll be able to find the most suitable lens type for your eyes.
Fittings for toric lenses might often require more time than the regular lens fittings you might be accustomed to, due to the relative complexity of the lens. Nevertheless, with advances in eye care, individuals with astigmatism have lots of life-improving options to choose from.
