Amblyopia is also known as "lazy eye," a disorder of the eye that is characterized by poor or blurry vision in an eye that is otherwise physically normal, or out of proportion to associated structural abnormalities.
Hyperopia, also known as hypermetropia or colloquially as farsightedness or longsightedness, is a defect of vision caused by an imperfection in the eye (often when the eyeball is too short or when the lens cannot become round enough), causing inability to focus on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. As an object moves towards the eye, the eye must increase its power to keep the image on the retina. If the power of the cornea and lens is insufficient, as in hypermetropia, the image will appear blurred.
Astigmatism is a refractive error of the eye in which there is a difference in degree of refraction in different meridians. That is, it is a deformation of either the cornea or the lens in the eye.

Astigmatism is when an optical system has different foci for rays that propagate in two perpendicular planes. If an optical system with astigmatism is used to form an image of a cross, the vertical and horizontal lines will be in sharp focus at two different distances.

Amblyopia: lazy eye. Untreated, the poor eye will go blind.
Hyperopia: farsightedness. Needs glasses.
Astigmatism: it's like sqeezing the lens in one direction or another. It's usually a defect in the cornea, though. Correctable with glasses.
