..I have noticed subtle changes in my vision,in the last few months,most thing slightly out of focus a little,my eyes sore.I have had prescription glasses for years for reading,maybe it's just I am 59 now but I also understand if a diabetic has blood sugar that is too high for too long,something called diabetic neuropathy can result,damaging your eyes.It is really not too bad,I car read just fine with reading glasses.SO:I have a call into my Dr. this morning,they was said they will set it up.........If it is that neuropathy stuff,I guess it is very treatable,but the most important thing is controlling your blood sugar...........Mine was 134 today........BUT: A new 6 string mistress is still in the works,regardless..............
