Hi there
when blood sugar levels are up and down, can cause eye pain and blurred vision! Do you have blood testing machine? just so that you can keep a eye on what your blood sugar levels are doing!
I know how you feel about the blurred vision and pain in your eyes, i have it for another reason!
I hope that your eyes will start to feel better soon! It is good that the eye tests are clear!
There are other people who can tell you more than i can as i am new to all the diabeties etc!
