Lazy eye, Astigmatism, cross eyed, Migraine and migraine aura

I have them all, but am a bit stuck, I have spectacles with a prism as i have the lazy eye condition but have been reading that just wearing stronger glasses makes the condition worse, so not sure if i should start reducing the number of times i wear them. I do have migraines 10 times a year and migraine aura 3 times a year (approx) and have been told i have astigmatism (this i am not convinced of as I dont match the symptoms for that). I am getting a feeling that getting stronger glasses every couple of years and help my eyes to get worse and would like some advice. I just got my new reading glasses and struggle to read my monitor more than 50 cms away, close up seems fine.
