Astigmatism question...fixing it?

So I wear glasses Because I have astigmatism in both eyes. From what Ive gathered, astigmatism is when your eye is not shaped exactly how it's supposed to, and it changes the way the light is reflected onto the receptors in your eye. I have been told previously by my eye Dr that if I do eye stretches it strengthens and uses the eye socket to theoretically reshape the eye thus aligning and improving vision.

.......I recently went back to the eye Dr and one of my eyes are better, the other eye has gotten a little worse. The eye that is better is my primarily used dominant eye. Has anyone ever fixed their astigmatism??? We're eye stretches the way you did it?... I've had glasses for 8 years, not totally bad vision but not 100% clear, obviously. Lol
