Mainly it's shape creates different focal and refractive powers which gives visual clarity, these are used to correct different types and levels of astigmatism. They are not used by people with mild astigmatism.
Many people have some degree of astigmatism. Only patients who tried and are not satisfied with the results of regular contact lenses tend to lean towards using toric lenses because of their cost. There are many types of toric lenses. They come in different textures, designs and colours to fit your eyes and lifestyle and budget. They are made of both soft and rigid gas-permeable materials. They are made either of a hydrogel or highly breathable silicone hydrogel.
