HELP Eyeglasses causing head pain leads to migraine

Greetings - what do you guys do, I have been to may doctors...any eyeglasses, even with padding, seem to hurt my eyes after awhile, leading to migraine. I have both types of vision issues, have tried bifocal contacts...the vision correction isn't spot on (it medically can't be), but it is close, but the lack of totally clear vision, ALSO leads to nausea and migraine with the contacts, and I find the strength of the contacts, to fade quickly. Anything on my head is a trigger, I can't wear my hair back even. Any advice? THANK YOU in advance. -Lisa
