Hello and welcome to the A/P!
I think I understand what you are talking about
...and yes, I have had the same weird vision disturbances.
I believe it stems from seeing something we are not sure is right/accurate...or having a concern about
our vision/perception...that then sparks some health anxiety.
We worry about
a neurological issue perhaps...or a health episode coming on...
This is common for those who suffer anxiety. We experience a normal bodily sensation and feel a bit 'off'...then the worries come flooding in.
If this is what you mean by your post...it could be that you could benefit from some help for health anxiety. If you are interested in learning more about
this...let me know, and I'll be happy to point you in the right direction to get started.
