Have you ever wondered about contact lenses as a way to correct astigmatism? A typical cornea is spherical, but in the case of someone with astigmatism, it's more elliptical. This alters how light hits the retina, and as a result, vision is out of focus.
The lenses eye doctors use to correct astigmatism are known as toric contact lenses. Toric lenses are constructed differently from regular lenses. Normal lenses have one power, but toric lenses have two: one for myopia or hyperopia and one for astigmatism. Compared with regular lenses, which can freely move around on your eye and have no effect on your vision, toric lenses need to stay in place. Toric lenses are therefore weighted on the bottom, and this helps them stay in place on your eye.
There are several scheduling options for toric contact lens users, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. Toric lenses are also available as color contact lenses, and as multifocal lenses. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher substance that keeps their form even when you blink, and sometimes provide even sharper vision than soft lenses. However, they are usually not as comfortable to wear. .
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 improvements in the field of optometry, individuals with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
