History
While regular astigmatism (astigmatism, astigmatism) does not normally change over the course of life, irregular astigmatism can progress steadily. This is especially the case when there is a permanent malformation of the cornea, in which the center of the cornea grows conically forward (so-called keratoconus). If the astigmatism is not corrected, severe headaches must be expected, as the eye tries to focus on the incorrectly seen image on its own, but fails to do so.
Prevention
It is NOT possible to prevent astigmatism. However, progression or development of accompanying symptoms such as headaches in children can be prevented by early correction of astigmatism with glasses.
