8. Vision Is Distorted
Whether it is blurry or you see floaters or flashes of light occasionally these are all signs that your blood sugar levels are higher than normal. Your vision becomes blurry as a result of the shape of the lens being altered when the levels of glucose in your blood are too high.
But the good thing is that this symptom can be reversed once your blood sugar levels return back to normal or as near to normal. However if the problem remains unchecked then of course this can lead to permanent damage to your eyes.
