Q: "Two weeks ago I was told by my Doctor that I have Type 2 diabetes. Since then my sugar levels have come down from 399 to 105 - 130 range. During the past two weeks my vision has become blurry. Some say this blurry vision will pass as blood sugars get more normal. What do you think?"
A: Blurred vision is a very common symptom when diabetes is out of control. When the blood glucose is high, there is also a higher glucose content in the lens of the eye. This causes the lens to absorb extra water, in an attempt to dilute the glucose in the lens.
As the blood glucose gets back to the normal range, the fluid leaves the lens.
Some people do not notice the blurred vision until their blood glucose is very high; others notice the blurred vision only when the blood glucose is returning to normal, as they are experiencing the change in fluid in the lens of the eye.
Your blood glucose was very high at diagnosis, so it is not surprising that you are experiencing blurred vision.
This process can take several weeks before the vision becomes stable, so eye doctors generally recommend that you not have your eyeglass prescription changed until your blood glucose has been stable for several weeks.
Always check with your physician and eye doctor to be sure.
