Have you ever wondered about contact lenses as an option to correct astigmatism? An eye with astigmatism has an oddly shaped cornea (football-shaped, as opposed to a normal, spherical cornea), 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.
The lenses eye doctors use to correct astigmatism are known as toric contact lenses. Toric lenses are constructed differently from regular lenses. Compared to ordinary lenses, which have one power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one for myopia or hyperopia. Because they feature two different strengths, these lenses must 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. Contact lenses for astigmatism are actually ballasted on the bottom, to prevent them from moving around on your eye.
There are a number of scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And people with astigmatism have no shortage of options; toric lenses also come in color, or as multifocals. Hard contact lenses are made from a firmer material that remains in shape even when you blink, and might provide even better vision than soft lenses. But they are usually less comfortable to wear. .
When it's time for your toric lens fitting, it's going to take some time, due to the complexity of the product. It might sound a little daunting, but it's worth the end result; effective treatment. Getting the best product for you will only improve your vision, and consequently, your everyday life.
