Does Vriska sees the world like this in her left eye?

Not completely- She only has 7 spots to gather light through on one eye, rather than it being a huge composite net of hexagons. Chances are her brain wouldn’t quite parse it like THAT either. However, checking Hussie’s more detailed drawings…

Those are individual pupils with their own irises, so yes her way of seeing would be kind of weird, with her left eye having 7 different points through which Light enters. I don’t know enough about Biology to know how that’d work though.
