Astigmatism refers to the defect where the lens of the eye produces a line image of a point source. Myopia is the defect where distant objects appear blurry, presbyopia is the gradual loss of the eye's ability to focus on nearby objects with age, and hyperopia is the defect where near objects appear blurry. None of these refer specifically to the production of a line image.
