A lot of people with astigmatism are under the impression that they are not able to wear contact lenses. But there’s actually a special kind of contact lens that corrects astigmatism. The cornea of a normally sighted person is round, but the cornea of someone with astigmatism is more oval-shaped, sort of like a football. This alters the way light enters the eye, and as a result, vision is unclear.
The lenses used to correct astigmatism are called toric contact lenses. Toric lenses are designed differently from regular lenses. Compared to ordinary lenses, which have the same power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one which addresses myopia or hyperopia. Compared with regular lenses, which can freely shift and have no effect on your vision, toric lenses need to stay in place. However, toric lenses are smartly designed with this in mind, and they are a little heavier at the bottom, which helps them stay in place.
Just like regular lenses, toric lenses come 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, have a stronger shape which allows them to stay put when you blink, but usually, they’re a little less comfortable than soft lenses. .
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. This all might seem like a bit of effort, but it’s worth the end result; effective, glasses-free treatment. Getting the best product for you will only improve your vision, and consequently, your everyday life.
