Can sight be correlated with my depression?

Okay, I know this sound really weird. So I have undiagnosed depression, but I'm quite sure I have it. I also wear glasses so my visions not great. But I've noticed something...on days where my depression is really bad, my eyes are just permanently slightly blurry. Even when I have glasses on. Kind of like what it looks like when you just wake up. Has anyone else noticed this or had this? I just want to know if this is normal for other people or just a coincidence.
