					Toric Contact Lenses: Soft Toric Contacts Can Correct Astigmatism
For years, patients suffering from astigmatism were told they could not correct their vision by wearing contact lenses. That all changed in 1978 when
the first toric contact lens was approved for distribution. By the late nineties astigmatic patients were able to finally wear disposable lenses and in 2002
CIBA Vision introduced Focus Dailies Toric, the worlds first daily disposable toric contact lens.


Whereas regular contact lenses only have one "prescription" or power, the toric contact lenses have 2 powers. They are created with curves at
differing angles - one angle for astigmatism and the other for either myopia or hyperpia. The toric lens is made to be more stable in your eye so that
blinking and moving your eye around will not move the lens around. This is important for those with astigmatism and results in crisper vision.


A Toric contact lens is different from regular soft contacts. First the contact lens is weighted so it will sit on your eye properly and keep the correction in
place. With normal soft contact lenses you can put the lens in any way as long as it is not inside out and be comfortable. With Toric contact lenses the
weight will position the contact on your eye and may cause discomfort or blurry vision for a few seconds while your eye blinks the Toric contact lens in
place.


Toric contact lenses have a special shape at the back of the surface, which fit your eyes perfectly. Made up of different kinds of plastics, the two main
groups of Toric contact lenses are soft and rigid gas permeable.


Not everyone with an astigmatism needs toric lenses. If the astigmatism is mild - between 0 and 1.00 diopter - you may be able to wear a soft or RGP
lens. RGP lenses might fare better as they are rigid and can use the tears in your eyes to work with the misshapen cornea. You might even be able to
use a high prescription of regular soft contacts. Your eye doctor will know which you need and you may have to try a few before you find the perfect
lens for you.


Rigid gas permeable Toric contact lenses. They are more durable and resist the accumulation of harmful materials. Priced reasonably they offer you a
clear vision though you may take a little time adjusting to them.
