Two separates: Myopia is very near vision and need for glasses beyond a foot or so. You may can read when very close to you but cannot see beyond arms length. Astigmatism is an irregular contour of the cornea and causes waviness and blurring in the pattern of sight. You can have one without the other. Your eye care professional can examine you and correct most of these problems. Seeing it clearer?

Different eye shapes: Myopia (nearsightedness) is difficulty seeing far. It is caused either by having a slightly longer eye or a cornea that is steeper than average (or both). Astigmatism is caused by the cornea not being round (more football shaped), causing distorted vision. They can occur alone or together. The degree of cornea irregularity and length of eye determine how strong a prescription lens your eye needs.
