Do Glasses Correcting Astigmatism Distort The Way Your Eyes Look?

Just curious if it makes your eyes look blurred or anything. Also, I was told I have really mild astigmatism and near perfect distance vision, but I got glasses though the doctor said I didn’t need to if I didn’t want to. My prescription states -.25 sph/ -.25 x60, and -.25 sph/ -.25 x100. All signs while driving looked blurry, but with the glasses look much clearer. Is it possible that my astigmatism is worse than the doctor thought? By looking at the prescription #s, is one eye worse than the other? I’m new to wearing glasses so I don’t know much about it. thanx.
