There are contact lenses for different eye issues
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.
Moreover, there are soft contact lenses which take up the eye's front part like a glove and do not have the capacity to rectify astigmatism in its fundamental spherical form. However, it can be designed with one axis to correct more refractive errors. This variety of lens calls for more care in fitting compared to average standard soft contact lenses. It is necessary since the angle and power of the astigmatic correction should be matched with that of your eye. 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.
