Have you ever wondered about contact lenses as a method of correcting astigmatism? An eye with astigmatism has an oddly shaped cornea, and that changes how light enters the eye. It’s not able to hit the retina properly, which drastically affects one’s ability to see clearly.
The lenses prescribed to correct astigmatism are known as toric contact lenses. The biggest difference between these and common lenses is the design. Compared to regular lenses, which have one power throughout the lens, toric lenses have two different powers; one for astigmatism, and one to fix trouble with distance vision. They are designed with curvatures at different angles. Because of how they’re made, these lenses must stay 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. However, toric lenses are cleverly designed with this in mind, and they are a little heavier at the bottom, which prevents them from moving around.
Just like regular lenses, toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you prefer multifocal or even colored contact lenses, then don’t worry, there are toric lenses for you. Hard contact lenses, also called rigid gas permeable lenses, have a firmer shape which allows them to stay put when you blink, but they aren’t always as comfortable as soft lenses. Together, we’ll be able to find the most suitable lens type for your eyes.
Toric lens fittings often take 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. But it’s worth it. With constant growth in eye care, those with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
