Not double vision but pain,pressure,and hard focusing eye problems I have and developed about a year into this condition. I went to 50 eye apts,10 eye specialists,neurologists for mri etc. I would cry from the pain. Anyhow for me I was dx with blepherititis and dry eye but they said it would not cause the pain I was in. My neuro did mris and I had scans of my eyes with still no dx. Every eye med or other treatment made it worse. Anyhow over the last while my eyes have gotten to a better point and I can't say from what. I still have flares though and 24/7 pain but not to the extreme. I also have RSD and it may be in my eyes but that is hard to dx.
Since you stated you have sjogrens I remember since I have a lot of symptoms of that I was on a forum and some had eye problems as well such as dry eye you stated you have which I thought I read could impact vision? When I had my mri of the brain I had one about a year before because of my leg pain but the neuro still wanted to repeat it. Also of my ear because I had pain there. Do you have any pain with the eyes or in your head area? Have you had blood work done lately and your thyroid tested? I ask because one eye specialist said thyroid issues could impact eyes but then I was also thinking lets say you had blood sugar problem etc that could also
Sorry I am not much help but hope you get some answers
