Hi Prue / Donna & welcome. Don't panic! What the information in leaflets and on the web doesn't always emphasise enough is that complications due to diabetes, such as sight problems, happen largely in poorly controlled diabetes and diabetes that has gone undiagnosed for a long time. So, the priority for you and your medical team is to find medication, blood testing regime, diet and activity levels that are appropraite for you and your situation. I'm guessing that your tablets are actually called metformin? It may take some time to find the right tablets and the right dosage, so you may have to return for "tweaking". Any questions, feel free to ask - there are many others who have personal experience of type 2 diabetes, unlike myself.
