High blood sugers or fluctuating blood sugars cause changes in vision. It is transitory. However I would suggest getting an opthomologist who deals with the retina, as you will need annual eye exams going forward. Trust me, you want thing caught BEFORE any vision is effected. Good luck! ;-)
I'm new here but very interested in this group since my own experience with eye problems due to high blood sugars (419) sent me home from work with a 12 week leave of absence because I could not see in the morning when I woke.
Several trips to the ophthalmologist I go to said I had a swollen lens that would take as long as three months to come back to normal after I got my blood sugars under control. I did that pronto and that's what actually caused my vision to go fluky, not when I had high sugars but when I brought it down to normal range with Lantus and pills. This all started October 6th and here it is Dec 6th and I still have the problem but I'm getting good readings after fasting. My H1c was 15.2 but dropped to 10.9 three weeks back when taken by the Endo Doctor that I asked for a second opinion. Has anyone ever experience this problem? Going out in bright sunlight and car headlights at night are also a problem. I hope some one can give me an insight on how long this takes to clear up.
It is different with everyone, but bringing from very high A1c levels to lower levels will have an effect on the eyes. The body is used to certain levels of hyperglycemia after time and once you change the amount of sugar in the system, it changes the chemical reaction to certain places in the body, mainly seen in the smallest blood vessels like the eyes. That said those changes are transitory and will improve with more consistent lower glycemic control.
No judgement but 15.2 is very very high and bringing it down is the best thing for your long term outlook. so congrats and keep up the good work, but only your eye dr will be able to tell you how your eyes are reacting to your changes and give an idea of how long it will take for the adjustments to settle down. Don't lose faith, you are doing the best thing for you. Good luck and keep at it. It WILL get better.
