Another vote for the springy Titanium frames. I suggest that you consider bifocals specifically for the bike. Reactolite or similar, anti-scratch, anti mist, anti reflection blah, blah.
Distance prescription for the main part and then either reading prescription or a cross between a monitor prescription and a reading prescription should allow you to see instruments and satnav, maps etc. You can tell the optician how high you want the reading prescription to start so that you can see everything you need to without it getting in the way of road vision.
Bifocals are easier to use, they cost a lot less than varifocals and if they don't look so good who gives a toss when you're riding. I had a pair like this for four years until I rode away from the STD this year and left them loose on the top of my bag :duh. Now awaiting a replacement set. Another Tosser at the "do" looked at them and pronounced them perfect for what he needed as well.
