Stick on bifocals with or without prescription lenses
I have progressive bifocals for my regular glasses.
But for my Rudy prescription inserts, I got distance only lenses and I use a cut down stick-on bifocal. I like it!
see this older thread "

I don't really want progressives on a bike. I like having all distance vision with a tiny reading bifocal. It was very weird the first ride or two, with the bifocal line in my vision. But after that, my brain adapted, and I never notice it now.
The prescription insert works great for me. The Rudy frames have interchangeable lenses. I have light yellow lenses for very dreary, cloudy days, extra dark mirror lenses for clear, bright sunny days, and photochromic lenses that transition to clear in a few minutes (and go dark in seconds). I use the photochromic most of the time.
