The astigmatism chart was designed to evaluate whether a person has astigmatism, which is a condition which results in blurry or distorted vision.

Why astigmatism cause objects to appear blurry?
An astigmatism means that the shape of the optics cause the focus to be a line rather than a point (the lenses are not spherical). Thus the image produced by these lenses is imperfect, causing a blurred image/vision.
Can you get astigmatism later in life?
Astigmatism means that either the cornea or the lens of the eye is not shaped properly bending light as it enters and creating multiple focal points which are seen as blurriness. Astigmatism is something you're born with. Most people, many who don't wear glasses have some astigmatism, but not enough to notice or cause any problems. Astigmatism may get better or worse while our eyes are still developing usually between the ages of 8-22, but it won't develop suddenly. As we get older, our eyes start to degenerate and we need glasses for reading. A doctor prescribing glasses for reading will correct a very slight astigmatism as well; if you're wearing glasses anyway, you might as well have the best vision possible.

Why are soft contacts no good for astigmatism?
Soft lenses cannot correct astigmatism because it only has a sphere lens. For a lens to correct astigmatism it must have both sphere and cylinder lenses. Cylindrical lenses are used to correct the power of the astigmatism at a certain axis, spheres are only capable of correcting power. But it's not exactly true that soft lenses are no good for astigmatism. They are, we call them Toric contact lenses.
