Makes no sense. Are you sure you weren't just looking at a picture
upside down?

The image that is focused on the retina of our eyes is upside down and
reversed right to left. It's the brain that reverses these around.
I've had several eye surgeries, and when there's a problem in the back
of your eye on the left side, it's the vision on the right that is lost.
