Well, of course not. Wearing too much contact lens can not lead to astigmatism. And generally speaking, contact lens can do a better job to correct the astigmatism. As we know that astigmatism is merely a visual condition of the eye that is caused by its shape, just like myopia and hyperopia. You should know that astigmatism is the result of an eye, which has two different powers, and it splits the focus point into two different partial focus points. And because of these different powers, it can lead to blurry vision, shadow images, eye muscle spasms, eyestrain, and headaches. But on the other hand, according to the doctors, you can just wear contact lenses to correct it, and contact lenses can be better than glasses.
