All I can offer is my own experience
The last glucose tolerance test i had caused blurred vision (in case anyone hasn’t had one of these, its a lot of glucose in a drink, with blood glucose tested at 0 mins and 120 mins to see if the body copes with the glucose).
I went into the test with my usual good eyesight.
During the test my blood glucose went sky high then dropped.
A few hours later I noticed the blurriness. It was bad enough that reading was difficult, using a computer screen nearly impossible, and driving was definitely dangerous! I kept trying to blink it away, but it kept coming back.
Two days later, my sight was back to normal.
It is the glucose affecting the liquid in the eyes, and it clears when blood glucose stabilises.
It is a different thing from retinopathy.
If you go to an optician when your eyes are affected like this by raised blood glucose then you will get told what your prescription is that day - which may be different tomorrow, or in a few weeks when your blood glucose stabilises nice and low again.
Sometimes people post on the forum saying they got new glasses when their blood glucose was still high, then had to go back to their old prescription when their sugars settled.
Obviously, I can’t state with certainty that this will happen to you, but the odds are good
Just focus on getting that blood glucose back under control.
