Hi Marky, You must still be reeling after your diagnosis, but welcome to the club! Try not to feel overwhelmed, on the positive side type-1 is diagnosed pretty soon after ur blood sugars become abnormally high, so as long as u get things under control, you should avoid long term complications. At this early stage it's important you don't put too much pressure on yourself to get exact control, it takes time to get it right.
I had similar prob with my eyes at diagnosis in my teens 20 years ago, but other way round! I'm short sighted anyway, but I could see really clearly, it was great, didn't need glasses or lenses for couple of weeks, went back to normal when my blood sugars went from 17 to normal levels.
I recommend you look up the Insulin Dependent Diabetes Trust website-IDDT. Interesting reading and good advice. They also have a helpline number, it's on their website.
Never rated Diabetes UK much,they sit on the fence too often and give misleading advice to general public in my opinion-although I became a member recently, but only to get involved in our local group, which I am now a commitee member.
Hope u get to grips with your condition. The key is to control your condition and not let it or the professionals control you, easier said than done sometimes! Take care
