Very common: It is very common to have refractive error but near-sightedness and astigmatism are more common that far-sightedness. There is also an association with keratoconus due to eye rubbing.

Astigmatism is a corneal or lens irregularity in focus and can present with a ghost image (double) with either eye open. Also, cataract can cause astigmatism and double vision with either eye open. It is very imporant to distinguish between single and both eyed double vision.

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?

????: Myopia or near sightedness and hyperopia, far sightedness, themselves don't cause blindness. They are treated with corrective lenses. However, extreme myopia or hyperopia can be associated with certain problems that can potentially blind you.
