Toric Contact Lenses for Astigmatism

Have you considered contact lenses as a method of correcting astigmatism? The cornea of a normally sighted person is spherical, but in the case of someone with astigmatism, it's more elliptical. This changes how light enters the eye, and as a result, vision is blurry.

The lenses used to correct astigmatism are called toric contact lenses. What differs between toric lenses and common contact lenses is the design. Compared to regular lenses, which have the same power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one for myopia or hyperopia. They feature curvatures at various angles. 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 heavier on the bottom, and this helps them stay in place on your eye.

Toric lenses are available 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, 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. .

Due to the fact that toric lenses are a little more complex, expect the fitting to take a little more time. Still, with advances in eye care, those with astigmatism have lots of life-improving options to choose from.
