The design of a good toric contact lens requires it to be made with great precision, which is what you get with a Cooper Vision Hydrasoft toric lens. But you also get a lens that's comfortable to wear. Even if you have astigmatism in only one eye, a pair of Cooper Vision Hydrasoft toric lenses can be made for you.

The reason that a toric contact lens requires more precision to make than a regular contact lens, is due to the nature of astigmatism. A normal cornea is evenly shaped like the surface of a ball. But an eye with astigmatism is curved more in one direction than in the other. And this makes the cornea slightly cylindrical like a ball that's been squeezed. In fact, your prescription for Cooper Vision Hydrasoft toric lenses includes a cylinder power to correct for this difference.

The introduction of soft contact lenses made wearing contacts a reality for more people due to the increased comfort they have compared to hard lenses. The reason that a soft lens is so comfortable is due to the fact that it's very water absorbent. For instance, Cooper Vision Hydrasoft toric lenses are 55% water. And this high water content makes the lenses flexible and able to adapt themselves to the shape of your eyes.

Although soft lenses are very comfortable, they do have a tendency to accumulate deposits of whatever they come in contact with. Even a conscientious cleaning may not get them all. So frequent replacement lenses were developed to overcome any problems from long-term buildups. These lenses have replacement schedules of every couple of weeks up to several months. For instance, the Cooper Vision Hydrasoft Toric Options lens gets replaced about every three months.

Some people have astigmatism in only one eye and so only need one toric lens. The design for the Cooper Vision Hydrasoft toric can also be made in a regular spherical lens. So you can have the same type of lens for both eyes, but one with astigmatism correction and the other without.
