Hi Guys
Hope you's had a good Christmas and happy new year. I'm back looking some advice on Monday and Tuesday I took blurred/double vision made driving very difficult had to cover one eye couldn't focus so rang optician went got eyes tested expecting to get re prescription and glasses. During the test I couldn't get the dot into one dot and was seeing two the optician asked re health I said about waiting to go to hospital and he got me to test my blood there and it was normal but he seemed to think that fluctuations in sugar level can affect sight like that and is writing a letter to my doctor to advise it to be checked when at hospital. Now I've been fine the last two days but I'm really concerned that my license could be taken off me? Anybody any advice about any of this? I need my car for work so I'm very concerned what could happen thanks in advance x
Hi,
I believe that it is only diabetics on insulin who are likely to have problems with the DVLA - and then only if they have hypos that need assistance from other people to get the BG back up.
But of course, you shouldn't be driving while you have vision problems!
Big fluctuations in BG do cause blurry vision. It is to do with the sugar entering the eyeball and altering the refractive index of the fluid. I think. Anyone know better?
I have had it myself, once, when I was given an Oral Glucose Tolerance Test, and my BG shot up hugely, and then dropped again. My vision was blurry for about 48 hrs, during which I wasn't safe to drive.
Haven't had it since, even on the very rare occasion that my BG gets higher than 10.
So, in answer to your query:
Your optician is probably right that the vision prob was caused by raised BG.
But it will subside - so long as you keep your BG at lower, more stable levels.
The real question is what had you been eating prior to the blurry eye episode?
And yes, had a great new year and Xmas, thanks!
