yep you can also get oedema or fluid retention on the retina so it is sometimes worth getting checked by a Dr or an optomotrist... there are ones that bulk bill out there so its definately worth doing! I was getting blurred vision after giving birth and went to the optomotrist thinking I'd have to get a new script for my glasses & apparently they corrected themselves during PG!! So I don't need glasses anymore! Its pretty crazy what our bodies do!
