I haven’t been diagnosed officially with Raynaud’s, but my grandpa is, and I display all of the symptoms.
Anyway, when I’ve been in the cold for too long and haven’t been able to get warm, my vision begins to get fuzzy, similar to when you stand up too fast. If it gets bad enough, I go completely blind, sometimes. I would guess that, if it is caused purely by Raynaud’s, then it would be some of the blood vessels in the back of my eye shrinking.
Other than another topic in this forum, I haven’t seen anything about people’s eyes being affected as well. I’m just wondering if anyone may know anything, or if it really seems to be unique.
