I have a pair of Flak Jackets with Transition lens and my distance prescription. Do the job very well and seem very robust; in a couple of big crashes they “fell apart”, you collect up the bits and click it all back together.
I don’t use them that much in winter preferring a pair of clear varifocals in Tag frame, frame is expensive but very good at staying put on my head without having to push it back up my nose. I am lucky to have two pairs courtesy of some Vision Express generosity, I keep one set specifically for riding.
Top tip for any of these expensive lens options, do not rub the trail crap off with the back of your glove, napkins, tissues, jersey etc or they get trashed. I have forced myself to clean mud etc off with fluid (typically squash from the Camelbak) and dry with a lens cloth or buff.
