A Closer Look at Astigmatism and Contact Lenses

If you have astigmatism and you think you can’t wear contacts, you’re mistaken. Contact lenses are actually a method of correcting the condition. Astigmatism means that your eye has a differently shaped cornea (it’s shaped like a football, as opposed to a normal, spherical cornea), and that changes how light enters the eye. It’s not able to come to a proper focal point on the retina, which dramatically affects one’s ability to see clearly.

The lenses prescribed to correct astigmatism are known as toric contact lenses. Toric lenses have a design that is different from that of regular lenses. As opposed to ordinary lenses, which have one power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one which addresses trouble with distance vision. Due to their particular design, toric lenses need to stay 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. Toric lenses are actually weighted on the bottom, and this prevents them from moving around on your eye.

Just like regular lenses, toric lenses are available as 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, 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. Rest assured, there’s a contact lens which perfectly suits your unique needs, and your eye care professional will find it for you.

Toric lens fittings are usually longer than regular lens fittings. This is because it’s a more complex product, and we want to make sure that you leave with a pair that fits you perfectly. Still, with constant growth in eyewear technology, individuals with astigmatism have lots of life-improving options to choose from.
