Why are soft contacts no good for astigmatism?
Soft lenses cannot correct astigmatism because it only has a sphere lens. For a lens to correct astigmatism it must have both sphere and cylinder lenses. Cylindrical lenses are used to correct the power of the astigmatism at a certain axis, spheres are only capable of correcting power. But it's not exactly true that soft lenses are no good for astigmatism. They are, we call them Toric contact lenses.
