Focusing on Astigmatism and Contact Lenses

If you are someone with astigmatism and you think you can't wear contacts, you're mistaken. Contact lenses can actually be a way to correct the condition. The cornea is generally spherical, but the cornea of an eye with astigmatism is more elliptical. This alters how light hits the retina, and results in blurred vision.

Toric contact lenses can fix astigmatism. Toric lenses have a design that differs from that of regular lenses. Normal lenses have one power, but toric lenses have two: one for distance vision and one for astigmatism. In contrast to regular lenses, which can freely shift and have no effect on your vision, toric lenses need to stay in place. Toric lenses are therefore ballasted on the bottom, and this helps them stay in place on your eye.

There are several scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And those with astigmatism need not worry about options; toric lenses even come in color, or as multifocals. Hard contact lenses, also called rigid gas permeable lenses, are made from a material that gives them a firmer shape which allows them to stay put when you blink, but usually, they're a little less agreeable to wear than soft lenses. Together, we'll be able to find the best brand to suit your eyes.

Due to the fact that toric lenses are just a bit more complex, expect the fitting to take a little more time. Still, with constant growth in the field of optometry, those with astigmatism have lots of life-improving options to choose from.
