Lots of people with astigmatism think they are not able to wear contact lenses. It may come as a surprise to know that there’s actually a unique type of contact lens that corrects astigmatism. Firstly, what’s astigmatism, anyway? An eye with astigmatism has an oddly shaped cornea, which alters how light enters the eye. The light doesn’t hit the retina properly, which dramatically changes one’s ability to see clearly.
Contact lenses that correct this condition, known as toric contact lenses, are manufactured from exactly the same material as regular spherical contact lenses. Toric lenses have a design that differs from that of regular lenses. Consider them almost like the bifocals of contact lenses; they have a power for your near or far sightedness and another for your astigmatism. They have curvatures at various angles. Compared with regular lenses, which can easily shift and have no effect on your vision, toric lenses need to stay in place. Toric lenses are therefore ballasted on the bottom, to prevent them from moving around on your eye.
Just like regular lenses, toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And people with astigmatism need not worry about options; toric lenses also come in color, or as multifocals. Hard contact lenses, also called rigid gas permeable lenses, provide a stronger shape which helps them stay in place, but usually, they’re a little less agreeable to wear than soft lenses.
Due to the fact that toric lenses are just a bit more complex, you should factor in some extra time for your fitting. It might sound a little daunting, but it’s worth the end result; effective, glasses-free treatment. Getting the best product for you will only improve your vision, and consequently, your everyday life.
