I wear prescription glasses with transition lenses. My only choice is a croakie, works great.
Au contraire, mon frere. I mean, not "au contraire" that a croakie works great -- probably true. But "au contraire" to the idea that that's your only choice. Following the link that BikeNC gave, I went on to another site that had a nice looking selection of prescription safety glasses, all available with a variety of lens options. (
