Ron, I assume by graduated you mean the trifocals. I have a set also and although supposedly being able to read with them I find them totally useless for anything close up, however they are the ducks guts for riding and reading the instruments. All those years I rode without being able to get my speed closer than around 3 or 4 kph and not being able to see the grey fine gravel on the road all because I couldn't see properly - makes the hair on the back of my neck stand up when I think about it now image
