HI I had blurred vision which was one of the first indicators of the Diabetes for me, I noticed at work the characters on the screen seemed blurred, and then when reading teletext or newspapers. I went along to optician thinking I needed some new glasses but he said no it was the sugar, and that my tear ducts were full of sugar, I had to bathe them everymorning for a little while. He would not give me any new glasses during this interim period as once it settles and the Diabetes comes under control it gets better. I do sometimes still get it if sugar is high.
