What do you do when you have to go the the opthometrist for new glasses? Since doing the DAFNE course my control is much better, but my blood sugar levels vary between 3 and 10 daily, so I am not sure if the reading taken will be correct. I have had loads of trouble in the past when I wanted new glasses (frames) with the same lenses. Everytime they test my eyes the reading is slightly different and I have to do the whole diabetes explaining thing to get glasses that I can actually see through... Although I have had the same lense strength for 20 years, I now think I might need different ones. Age is a cruel thing...
