You can improve your vision and the appearance of your eyes with a toric colored contact lens. The comfort of today's soft contact lenses make it practical to accent or change the color of your eyes whenever you want. A toric colored contact lens gives you the chance to better your sight while having a little fun with the look of your eyes.

A toric colored contact lens corrects for the vision problem of astigmatism. Because the effects of astigmatism range in severity, some people are so little affected, they're unaware of their condition. But severe or not, the cause is an imperfectly shaped cornea or sometimes the lens. The surface of a normal cornea is like a ball and curves evenly in all directions. But if you take a soft rubber ball and squeeze it you'd approximate the shape of an astigmatic cornea. It curves more sharply in one direction than the others.

To provide consistent vision correction, a toric colored contact lens requires two things. Of course first, it has to be made to the right specifications. And secondly, it has to remain properly positioned when worn. A regular contact lens is curved evenly like a normal cornea. And if a regular lens is rotated or moved slightly to one side, your vision is unaffected. But a toric lens has a set position, so it must be designed to resist moving out of position, every time you blink.

After you've found a toric colored contact lens that you feel will give you good optical performance, you need to make your color choice. For instance, the DuraSoft 2 OptiFit toric lens made by CIBA Vision, gives you two options. If you have light color eyes and want to add to your natural color, you can get enhancement tints. The lens contains a light layer of tint that deepens your eye color without affecting your sight.

The other option offered by the DuraSoft 2 lens is for changing eye color. The tint in this style is opaque, so when it covers your iris only the color of the lens shows. Of course the center of the lens over your pupil is left clear. This toric colored contact lens is meant for either daily wear or up to a week of continuous use. CIBA Vision also offers a frequent replacement type lens with their FreshLook color toric.
