This happens to me too, it is a very common symptom of high blood glucose.
It goes away when sugar is under control. The trick is to try to keep sugar levels in the normal range.
Hi again
the blurred vision happens to me anything over 10.5. I try to keep tighter control than that, but it does happen occasionally. Are you on meds? 15 seems very high, if it goes that high regularly you may need a change or increase in meds. Mandy.
Hi Molly: Yes I take Amaryl twice a day. I used to take Metformin but had to quit because of bowel problems. Amaryl does not work as good. My sugar goes above 12 if I cheat and eat wrong---like chocolate.. my downfall.
Glad to see someone else uses mmol. I have to convert if I am using USA readings.
Diagnosed 5 years ago., Diet and exercise for 2 years. Metformin for 2 years and now Amaryl.
