I like these Liberty Sport glasses from Lenscrafters. I got my first pair at Kaiser, but they stopped carrying them, so now I go to Lenscrafters. These are blended tri-focals, but fixed shade density. I don't know if they make Transition type lenses. My first pair had black frames, these are bronze. Dorky picture, but you get the idea. They cater to moto type riders, but work great for us pedal pushers too.
