it also happens in movies like when the pan the camera over sentences I cant read it because its blurred.
I am nearsighted and have astigmatism in one eye, my left one.

Would Contact Lenses Affect My Tennis Playing?

Well, I have an astigmatism and have like 20/80 or something or something around there. so i have been going to my eye doctor and got glasses and am trying on different contact lenses.
QUESTION with my condition, would contact lenses help me play tennis better? cus i tryed playing with them once and i seemed to play worse… is the prescription wrong? or would i start out worse and gradually play better than i was because i have to get used to playing tennis in them? would contacts help?
