Undiagnosed vision problem

[Visionproblem]

I have an undiagnosed vision problem 24/7 never goes away only gets worse. I'm a 56 year old female problem began when I was 19. Eye do says healthy optic nerve, neurologist tested for ms, seizures, etc via MRI, MRA, spinal tap, eeg, blood work, medications including anxiety meds with no relief except Neurontin helped for a short time. He says he wished he could be my hero and give me diagnosis but he can't. I been to shrinks and they say it's medical not mental. It's not blurry it's like inability to visually vocus. I have an issue with depth perception and see snow on light backgrounds. I do have anxiety but no meds help it. It doesn't get worse during an anxiety attack. It gets worse after fevers, migraines, stress but not always. I had improvement but not completely gone during my 2nd trimesters of all three children.

Anyone else suffer like this???
