A Guide on Toric Contact Lenses

By Adriana Noton


There are various types of contact lenses available that are designed to improve vision. Astigmatism is one eye condition that many people suffer from. In the past, people with astigmatism were told they could wear soft contact lenses. Fortunately, thanks to developments in contact lenses, people with astigmatism can now wear special contact lenses which will help them see clearly. These special contact lenses are called Toric Contacts Lenses.

What are Toric Contact Lenses?

Toric contact lenses are contact lenses that are made from the same materials as spherical contacts lenses which enable them to be ether RGP or soft. However, what makes them different is how these lenses are designed. For instance, Toric lenses contain two powers which have been made with curvatures at different angles. One angle is for astigmatism, and the angle is for hyperopia or myopia. When the wearer blinks, the contacts have a mechanism that keeps the lens in position. The result is clear vision because the contact will not be rotating on the eye.

Astigmatism and Rigid Gas Permeable (RGP) Contact Lenses

RGP contact lenses are able to keep their shape when they are resting on the cornea. They also provide sharp vision when worn by people with astigmatism. They provide a high degree of clarity. However, many people choose soft Toric lenses as they more comfortable when they are first worn. RGP takes a getting used to so it requires some patience.

Disposable, Color, and Multifocal Toric Lenses

Toric contact lenses are available in different types such as disposable, frequent replacement, color, and multifocal Toric lenses. You can choose from a variety of colors to enhance your eye color. You may also be able to get disposables but it will depend on your prescription. However, you can still get non-disposable Toric lenses. Multifocal Torics are available for people who have presbyopia and astigmatism. These are usually non-disposable as well.

Astigmatism and Silicone Hydrogel Toric Lenses

There are a number of Toric silicone hydrogel contact lenses on the market. You can even get monthly wear Toric silicone hydrogel contacts. These contact lenses allow much more oxygen to pass through to the cornea which is healthy for the eye. Silicone hydrogel lenses offer the following benefits: more resistance to protein deposits, reduced risk of eye infections, easier to handle, and there is less drying of the lenses.

Cost of Toric Contact Lenses

For such special contact lenses like Torics, it would seem like these contacts would be very expensive, however, consumers can get these lenses quite cheaply. Once you have been fitted for these lenses by your optician and have received a prescription, you can go online and shop at a professional and reputable online Acuvue contact lens retailer. You will find contact lenses being offered at greatly discounted prices and they are much cheaper than traditional contact lens retailers. Thanks to technological innovations in contact lenses, many people with astigmatism can get Toric contacts at discounted prices.
