Contacts For Astigmatism- Toric Contact LensesAstigmatism is a kind of focusing error where images appear as blurred. People who suffer from Astigmatism have problems at night rather than daytime. But now there is a solution for all those suffering from this disorder. They can switch to contacts for Astigmatism. Contact lenses as well as spectacles can correct this vision disorder. As regards the cause of Astigmatism it is often believed that because of the shape of the cornea of the eye or because of some tilt in the lens of the eye the images appears blurred to a person. It is also believed to be a hereditary disorder. People with astigmatism have a lot of problem identifying objects that are kept at a greater distance. You may try to identify the object but this may cause excessive strain on the muscles of the eye and thus often people with Astigmatism complain of fatigue, headache as well difficulties in concentration. There is also another interesting thing associated with Astigmatism. Correction of Astigmatism with the help of contact lenses or spectacles does not occur every time. In some cases people may experience difference in size and shapes of things after correction. This can affect the patient's judgment of distance like the patient may feel himself to be taller or shorter and sometimes even the floor may appear curved and the walls may look sloppy. For astigmatism contacts that are prescribed are called toric lenses. Toric lenses are made of the same material as that of soft lens. People with astigmatism experience greater comfort after using toric lenses. In regular contact lenses you have only one power whereas in the case of toric lenses there are two powers. Also they are made with curves at different angles- one especially for astigmatism and the other for myopia or hyperpia. Also toric lenses are made in such a way that they fit your eye completely. So that so, that even when you blink the eye the lens does not move around. This thing is very important to give people with astigmatism a better and crisper vision. Toric lenses require better fitting and also they must be exact. Thus toric lenses can be expensive as well as take some time to be manufactured. You should also be aware of the fact here that not everyone with astigmatism is required to wear toric lenses. People suffering from mild astigmatism are often referred as to 0 to 1 diopter need not wear toric contact lenses. Instead here people with mild astigmatism wear Rigid Gas Permeable lens or a soft lens. Rigid Gas Permeable lens are used more as they can capture the tears and then try to reshape the cornea. Contacts for astigmatism of the mild type can also be prescribed by doctors. But here your doctor will try out a few ones before finding the right astigmatism contact lenses. |
