Astigmatism Doesn’t Rule Out Contact Lenses

If you have astigmatism and you don't wear contacts, then listen up. Contact lenses are actually a method of correcting the condition. To begin, what is astigmatism? An eye with astigmatism has an oddly shaped cornea (it's shaped like a football, as opposed to a normal, spherical cornea), and that changes how light enters the eye. The light doesn't hit the retina properly, which affects one's ability to see clearly.

Contact lenses designed to correct this condition, which are called toric contact lenses, are manufactured from exactly the same material as regular lenses. What separates these from common contact lenses is the design. Consider them almost like the bifocals of contact lenses; they contain one power to fix your distance vision issues and another for your astigmatism. They have curvatures at different angles. Since they feature two different powers, these lenses need to remain in place on your eye in order to correct your vision, as opposed to spherical contact lenses, which have no effect if they rotate on your eye when you blink. Contact lenses for astigmatism are therefore ballasted on the bottom, and this helps them stay in place on your eye.

There are a number of scheduling options for toric contact lens wearers, including 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, 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. Rest assured, there's a contact lens which is just right for you.

When it's time for your toric lens fitting, it's going to take some time, due to the complexity of the product. Nevertheless, with advances in eyewear technology, individuals with astigmatism have lots of life-improving options to choose from.
