I don't have blurry vision but have maor eye pain and problems with spots. I have been to 11 specialist for this issue alone,mri,scans etc. They still are clueless of why I have this. I do have belpheritis and dry eye but it should not cause this level of pain. I have had a hard time getting a doc to connect the PN/RSD and the eyes. I have heard others mention though blurry with conditions like this. I hope you find a doctor to give you answers and relief. Also I wonder have you started any new meds that could contribute?
