If you are someone with astigmatism and you don’t wear contacts, then you’ll be interested to hear this. Contact lenses are actually a method of correcting the condition. An eye with astigmatism has an irregularly shaped cornea (it’s shaped like a football, unlike a normal cornea, which is round), which means that light entering your eye through the cornea struggles to come to a single focal point on the retina, resulting in blurred vision.
Toric contact lenses can rectify astigmatism. The main difference between these and regular lenses is the design. Regular lenses have just one power, but toric lenses have two: one for distance vision and one for astigmatism. Due to their particular design, these lenses need to remain in place on your eye in order to correct your vision, unlike spherical contact lenses, which have no effect if they rotate on your eye when you blink. But toric lenses are cleverly designed with this in mind, and they are weighted slightly at the bottom, which helps them stay in place.
Toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. If you like to wear colored or multifocal lenses, there are toric lenses made to suit your needs too. 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 they aren’t always as comfortable as soft lenses. .
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. It might sound a little daunting, but it’s well worth the end result; effective, glasses-free treatment. Being fitted with the right product will only improve your vision, and consequently, your quality of life.
