Hyperopia: When the optics are too weak for the length of the eyeball, one has hyperopia or farsightedness.

 

Astigmatism: People with a simple astigmatic refractive error see contours of a particular orientation as blurred, but see contours with orientations at right angles as clear. When one has a cylindrical error, one has astigmatism.
