Toric Contact Lenses for Astigmatism

If you have astigmatism and you don’t wear contact lenses, then you’ll be interested to hear this. Contact lenses can actually be a way to correct the condition. Firstly, what is astigmatism? An eye with astigmatism has a differently shaped cornea (football-shaped, as opposed to a normal, spherical cornea), and that changes how light enters the eye. It’s not able to hit the retina properly, which affects one’s ability to see clearly.

The lenses prescribed to correct astigmatism are called toric contact lenses. What differs between toric lenses and regular lenses is the design. Regular lenses have just one power, but toric lenses have two: one for myopia or hyperopia and one for astigmatism. They are designed with curvatures at different angles. Because they contain 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, where slight movement due to actions like blinking have no effect on your vision. However, toric lenses are smartly 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. Toric lenses are also available as color contact lenses, and as multifocal lenses. Hard contact lenses are made from a harder substance that remains in shape when you blink, and sometimes give even better vision than other lenses. But they are usually not as comfortable. There’s a contact lens which is just right for you.

Toric contact lens fittings might sometimes need more time than regular contact lens fittings, due to the relative complexity of the lens. This all might seem like a bit of effort, but it’s worth the end result; effective treatment. Getting the right product will only improve your vision, and consequently, your everyday life.
