. One of the common disorders is known as Astigmatism. More than 90 percent of people have experienced some problems with blurred vision which is the primary symptom of this structural defect in the eye.

This disorder can also be produced by the abnormality or sloping of the natural lens inside your eye.

In the past, it was quite difficult to correct astigmatism with contact lenses compared to the use of eyeglasses. However, the situation has been reversed. Many of these minute eye devices have been designed to remedy astigmatism. These are known as toric lenses and come in a broad assortment of lens, materials, fittings, patterns, and power. There are also bifocal and multifocal lenses which are made for presbyopia or defect in vision due to old age.

These are daily contact lenses but can be changed daily, two times each week, or monthly depending on the lens and your eye. Certain customized and special lenses for astigmatism are changed after longer interludes. These lenses come in silicone hydrogel materials together with customary soft lens materials.

Rigid gas-permeable lenses are not consistent with the shape of the eye because of its rigid nature. These have the capacity to cope with low to medium stages of astigmatism in its basic form. For more serious astigmatism, this can be made with one axis which can correct more refractive error than the other. This type of lens entails more care in fitting as against the gas-permeable contact lenses. The angle and power of the astigmatic correction needs to be harmonized with that of the eye. These lenses are worn during the day only and last from six to 12 months under normal conditions.
