A Closer Look at Astigmatism and Contact Lenses

Have you considered contact lenses as a method of correcting astigmatism? The cornea of a normally sighted person is spherical, but when you have astigmatism, it's more elliptical. This ostensibly small detail actually affects the way light hits the retina, and results in blurred vision.

Toric contact lenses are used to rectify astigmatism. Toric lenses are designed differently from regular lenses. As opposed to ordinary lenses, which have one power throughout the lens, toric lenses have two different powers; one which addresses astigmatism, and one which addresses myopia or hyperopia. Because of their multiple powers, toric lenses need to remain in place on your eye. This is different from normal lenses, which can shift slightly and not affect your sight. A handy feature of toric lenses is the fact that they're weighted at the bottom, which helps them stay put when you blink or rub your eyes.

Toric lenses come as soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And people 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 stronger shape which allows them to stay put when you blink, but they aren't always as comfortable as soft lenses. Together, we can find the most suitable lens type for your eyes.

Toric lens fittings often take longer than normal 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. It might sound a little daunting, but it's well worth the end result; getting treated, glasses-free. Getting the best product for you will only improve your vision, and thus your everyday life.
