If you are someone with astigmatism and you don't wear contacts, then you'll be interested to hear this. Contact lenses can actually be a way to correct the condition. Firstly, what's astigmatism, anyway? Astigmatism means that your eye has a differently shaped cornea (football-shaped, as opposed to a normal, spherical cornea), which changes how light enters the eye. It's not able to come to a proper focal point on the retina, which dramatically changes one's ability to see clearly.
Toric contact lenses are used to rectify astigmatism. What separates these from common lenses is the design. Think of them as almost like the bifocals of contact lenses; they contain one power for your distance vision issues and another for your astigmatism. Compared with regular lenses, which can easily move around on your eye and have no effect on your vision, toric lenses must stay in place. However, toric lenses are cleverly designed with this issue in mind, and they are weighted slightly at the bottom, which helps them stay in place.
There are several scheduling options for toric contact lens users, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And folks with astigmatism have no shortage of options; toric lenses also come in color, or as multifocals. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher substance that keeps their form when you blink, and sometimes give sharper vision than soft lenses. But they are often not as comfortable. .
Toric contact lens fittings can often require more time than the regular lens fittings you might be accustomed to, due to the fact that these lenses are a little more complex. It might sound a little daunting, but it's well worth the end result; getting treated, glasses-free. Being fitted with the best product for you will only improve your vision, and consequently, your everyday life.
