Astigmatism will not change with any exercise techniques. The main cause of astigmatism is congenital, which means that astigmatism can be present after birth when the shape of the cornea is basically set. Astigmatism can be retro-random, parsimonious, or oblique axis astigmatism. Astigmatism is generally stable and may change mildly with age or changes in eye habits, and changes in astigmatism cannot be corrected by exercise. For myopic astigmatism, if you pay attention to eye health and reasonable eye use, the change may not be too great, while farsighted astigmatism may gradually diminish in degree with age.
