Yup.
Just a note about your opticians appointment. Remember to tell the optician of your Diabetes status.
If you are suffering from blurry vision this may be due to high bg levels but it could also be due to improving bg levels as our eyes take a little longer to adjust to changes in diet/levels of glucose. Some people get over the blurry vision in days or weeks some people find it takes a little longer. So, if this is you, do not run at buying new specs because you may waste your money. If this is not you then all is good.
