My sister has Sjogren's or some kind of similar autoimmune disorder since diagnosis of our autoimmune diseases is often imprecise and difficult to pin down.

I also developed some vision disturbance in my right eye right before my hernia repair. It was dilated and examined and nothing abnormal showed up but vision became dimmer and more cloudy. Sort of like looking through a dirty lens except it is clear according to optometrist who examined me. I have had diabetes for decades and think it might be related to some thing in optic nerve area but need to wait for further exam by regular ophthalmologist who has pix from previous exams to sort it out.
