OSCILLOPSIA
As well as Nystagmus…at one point I had Oscillopsia. This is something else that causes vision to ‘jiggle’.
Mine kicked in when I was walking around, it caused my field of vision to be unsteady …thankfully it resolved of it’s own accord.
There are medications to try for this diagnosis…
Oscillopsia is a vision problem in which still objects seem to jump, jiggle, or vibrate due to a misalignment of the eyes or systems controlling balance.
