What condition of the eyes is caused by the cornea not being spherical which causes an irregular focusing of light rays entering the eye?
Astigmatism is an inability of the eye to clearly focus images from any distance. This can occur because the shape of the cornea is not perfectly spherical.Hyperopia (Farsightedness) is a focusing problem usually resulting from an eye that is too small, or a cornea that is too flat.Myopia (Nearsightedness) occurs when the eye is too long in relation to it's focusing parts, or the cornea is to steep.
Why do people have astigmatism and Does it mean your eye is messed up?

Where in the eye does the refraction take place?
