Astigmatism Doesn’t Rule Out Contact Lenses

Many people with astigmatism think they can't use contact lenses due to their condition. Well, there's actually a special kind of contact lens that corrects astigmatism. An eye with astigmatism has an oddly shaped cornea (football-shaped, as opposed to a normal, spherical cornea), and that changes how light enters the eye. The light doesn't come to a proper focal point on the retina, which dramatically affects one's ability to see clearly.

Contact lenses that fix this condition, known as toric contact lenses, are made from the same material as regular spherical contact lenses. Toric lenses have a design that differs from that of regular lenses. Normal lenses have just one power, but toric lenses have two: one for myopia or hyperopia and one for astigmatism. They feature curvatures at various angles. Because of how they're constructed, toric lenses need to remain in place on your eye in order to correct your vision, as opposed to normal contact lenses, which have no effect if they rotate on your eye when you blink. But lenses for astigmatism are smartly designed with this issue in mind, and they are a little heavier at the bottom, which helps them stay in place.

There are several scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you are used to colored or multifocal lenses, there are toric lenses for you. Hard contact lenses, also called rigid gas permeable lenses, provide a firmer shape which allows them to stay put when you blink, but usually, they're a little less agreeable to wear than soft lenses. .

Fittings for toric lenses may often need more time than regular contact lens fittings, due to the relative complexity of the lens. It might seem like a bit of effort, but it's worth the end result; getting treated, glasses-free. Getting the right product will only improve your vision, and thus your everyday life.
