So, I was DX'd with Type II last Monday (a week ago). I immediately changed my diet, started moderate exercise daily (I'm pretty out of shape, so I started light), and I'm testing frequently and taking my 15cc of Lantus daily. Everything seems to be going well, except…my vision is noticeably worse. It started on Sunday evening. I called my doctor, and she insists that the Lantus shouldn't be causing the problem. However, I just had my eyes checked in December (full test with dilation), and they were fine. Also, my BP was fine as of last week, and my exercise is not overly strenuous.

My next appointment with the doctor isn't scheduled until next week, and I don't yet see a need to go to the ER, but…what is messing with my eyes?

Does anyone have any experience that could shed some light on this?

Blurry vision - sounds very familiar. When I was first diagnosed, and my bg #'s were all over the board, I noticed my vision immediately. As I got the bg"s down and more in control, my eyesight straightened out. I went to the Dr and he said I did not need to spend money on glasses, wait till my bg"s really settled and then come back.I did and I did not need glasses. It was the taking of control that got my vision back normally. Good Luck to you.

Thanks for this info! I have been sitting here thinking I was going crazy with my eyes. I've had blurry vision all week. I even thought the other day I might need bifocals at 34! I was having that much trouble with my old prescription! I am happy that I am going to see the eye doc in 3 weeks then! Since my bs# are now in normal ranges and have been for a few weeks now with meds. (oral, thank goodness!) You've eased my mind considerably!

Hello - Before I knew that I was having problems with my blood sugars, my vision went blurry. I didn't think anything of it…I weat contacts, so I thought that maybe I accidentally got my left and right contact mixed up. But, this went on for 3 days, and got exponentially worse, to the point where I didn't trust myself to drive. Finally, I checked my blood sugar…475. It wasn't until I got to the Dr. and got put on insulin that it got better. So, I would definitely be checking my levels, because that's a huge culprit.

My levels are in the 100-250 range at this stage, but were much higher before diagnosed (A1C of 14)e. They were that high when I got my prescription in December.

i am so glad to hear this response. since i changed my diet 6 weeks ago my vision has also blurred at times and I have been wondering if its because I am slightly over 40, lol. glad to know that it is just might be my body adjusting. I am being rechecked next month and will mention it to my dr.
thx for the post

It sounds like you and I are in the same boat. I'm glad the discussion helped, and I'm equally glad to hear that others' experiences support the theoretical explanation of what the heck is wrong with my own vision. My next followup with my doctor is next week, but I will wait a few weeks before getting yet another eye exam.

KD is spot-on. I had blurry vision years ago and was a bit concerned too.
I learned that it was my High BGs at the time which changed the shape of my eyeball, changing the focal point. The clear jelly in the eyeball (the "vitreous matter") does take on high sugars, but does so very slowly as there is no blood flow directly in the vitreous. Since there is not a lot of circulation in the vitreous it takes a while for the BG level in the vitreous to change, either up or down.

It is recommended that when your vision is blurry that you work on getting your BG#s down closer to normal, and wait about 2 weeks for your vitreous BG level to decline before you go to get your eyes checked for prescription eyewear. Otherwise you may be wasting your money with a wrong prescription.

It's common to get blurry vision as your blood sugar gets lower, it's part of your body adjusting. Your eyes might have been fine when they were tested but that was when you had high blood sugars, your body would have adjusted to compensate. It has to do the same again.

Just as an FYI in case of emergency, you don't take 15cc of Lantus, you take 15 units. 15cc would be 1500 units and would kill you if somebody decided to give it to you in an emergency situation.
