Michaela, how horrid, but it probably isn't neuropathy damage, as that usually takes some years to unfold. It may be just blood sugar levels that exert their darling little (temporary) changes on the lenses in your eyes. Because the specific gravity of the liquid in our eyes is changed by high BG, the poor lenses change their shape a bit. This screws up the vision.
It's completely reversible with six to eight weeks of lower and consistent BG.
If that's what this is, then key for you is getting your BG down and flat.
That means low carb, in my experience, ie dropping all starchy foods - bread, potatoes, rice, pasta, and fruit. Sorry if you know all this. If you don't, the Diet Doctor site a useful guide to low carb.
Your BG doesn't sound hugely high, bet it may be that your particular organism requires low BGs.
