Late last night, one of my eyes felt strange. Cloudy/blurry. Very briefly when I closed the other eye, it was as though the affected eye had a veil over it - I could see, but it was noticeably darker in that eye. This happened for a few minutes, I went to sleep, woke up this morning and all ok but that eye does feel like I have something in it but can’t nothings coming out or visibly there.
I’m permanently tired and stressed, would this affect my vision at random? Or does this sound like some sort of emergency?
