Focusing on Astigmatism and Contact Lenses

So many people with astigmatism are under the impression that they are not able to wear contact lenses. Well, there's actually a unique kind of contact lens that corrects astigmatism. To begin, what is astigmatism? Astigmatism means that your eye has an oddly shaped cornea, which means that light entering your eye through the cornea isn't able to come to a single focal point on the retina, resulting in blurred vision.

Toric contact lenses are used to fix this condition. Toric lenses are constructed differently from regular lenses. Compared to regular lenses, which have the same power throughout the lens, toric lenses have two different powers; one for astigmatism, and one which addresses trouble with distance vision. They are designed with curvatures at various angles. Due to their unique design, these lenses need to remain in place on your eye in order to correct your vision, as opposed to spherical contact lenses, where lens movement due to blinking has no effect on your vision. Toric lenses are actually weighted on the bottom, to prevent them from moving around on your eye.

There are multiple scheduling options for toric contact lens wearers, 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. Hard contact lenses are made from a harder substance that keeps their shape when you blink, and might give better vision than soft lenses. But the downside is that they are usually not as comfortable. .

Fittings for toric lenses can sometimes take up more time than regular contact lens fittings, because of the relative complexity of the lens. Still, with advances in eye care, those with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
