Blurred vision

[Shaz3004]

I have started a low carb diet and my vision is a bit blurred. I read that it could be that when your blood sugars reduced that it takes a while for your eyes to adjust. Does anyone know about this? or can offer a reason for it, it’s been a week so far, two weeks into the diet. Thanks

This is part of a link from John Hopkins University:
Another potential effect from diabetes is swelling of the eye lens, leading to blurry vision. If your blood sugar levels change quickly from low to normal, the shape of your eye’s lens can be affected and your vision can be blurred. Your vision goes back to normal after your blood sugar stabilizes. “If you’re getting eyeglasses, make sure your blood sugar levels are controlled before your exam so that you can get the most accurate glasses prescription,”

Patients are all different so the time varies accordingly. It helps to be stabilised for a significant period. In your case it may be a few days more. It is scary, but been there and recovered!! Good luck!

I agree, know of several people to whom this has happened. Worst case was 12 weeks, but most were much less. Advice was to get cheap (pond Shop) spec to tide over the BG adjustment.
It didn't happen to me, but my HbA1C was only 53 when I started low carb.

My vision fluctuates and somewhere on this website there is a thread about changing and blurring vision via which I learned others have this problem too. My sugars are relatively stable, almost always in range. Although I don't have a cgm, I test my blood for the after-meal peak to see how high I go and about 3 hours after first bite to see if the insulin I took is lowering the blood sugar level as expected. When my sugar is near ten, my vision is worse, and when my sugar is in the 4s and 5s, it's best; then if by accident I go below below 3.3 I see stars. I'm always changing glasses. No complaints though - I can still see and don't have retinopathy.

It happened to me, but very soon sorted itself out. I hope yours will too.

Yep, prescription has changed a couple of times - the big change was right at the start but that worked through in about 4-6 weeks. I found that my older glasses were better than the most recent ones.

I used to get red stars. On rare occasions they would be blue - very strange!
