-How do you reduce it? Well, in the same way as you reduce your myopia, in small steps. If you have only a small amount of astigmatism, say .25D, you could drop your astigmatism correction straight away. If you have a lot, it will be more complicated to tackle.
-Astigmatism often reduces spontaneously as myopia is corrected.
