Toric Contact Lenses: A Great Way To Correct Astigmatism

If you have astigmatism and you think you can't wear contacts, you're mistaken. Contact lenses are actually a method of correcting the condition. Generally, the cornea is spherical, but in the case of someone with astigmatism, it's more elliptical. This seemingly minor feature actually alters the way light hits the retina, and results in blurred vision.

Contact lenses that correct astigmatism, known as toric contact lenses, are constructed from the same material as regular spherical contact lenses. What differs between these and regular contact lenses is the design. As opposed to regular lenses, which have one power throughout the lens, toric lenses have two different powers; one for astigmatism, and one for trouble with distance vision. They feature curvatures at various angles. Due to their multiple powers, toric lenses must remain in place on your eye. This is not the case with regular lenses, which can shift slightly and not affect your sight. Toric lenses are therefore weighted on the bottom, to prevent them from moving around 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 material that keeps their shape when you rub your eyes or blink, and sometimes give better vision than soft lenses. But the downside is that they are usually less comfortable to wear. Together, we can find the most suitable lens type for your eyes.

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 seem like a bit of effort, but it's worth the end result; effective treatment. Getting the right product will only improve your vision, and consequently, your everyday life.
