Homonymous Hemianopsia. Occurred when I had a stroke during a heart procedure.
I have zero visual field on the left and I'm missing some top, bottom & on the right. I pretty much have only tunnel vision on one side.
I also have
$1 also caused by the stroke. I have colours & patterns similar to what you see in a kaleidoscope overlaid on top of my remaining vision that is more prominent in low light (I'm 100% blind at night conditions) or where there is a large patch of blank space, like walls & floors.
