Since starting medication and adopting a low carb diet my vision is quite blurred at times, especially when trying to read tiny text (Collins Carb Counter is a waste of money as I can't read the thing). My doc said that it's just the change in sugar levels affecting the pressure inside my eyeballs and it will settle down. How long will this take? I need to make a diabetic eye appointment, I've always wore glasses and have had a stable prescription all my adult life, how long should I leave it to settle befor getting my eyes tested?
