fwiw I've tried two or three different pairs of cycling glasses with prescription inserts, and the inserts always annoyed me because my eyelashes would bat up against them. I eventually switched over to genuine prescription lenses (glass ground by an optician, no insert) and couldn't be happier
...well, I suppose my wallet could be happier.
But going to an optician who is well-versed in cycling needs was a huge asset. I used SportsOptical.com in Denver. One of their observations was that because of the extremely high strength of my prescription -- myopia + astigmatism + age-related presbyopia (necessitating a very thick, highly curved lens with a bifocal component) -- there were very few frames on the market that could accommodate such a lens without compromising the optics.
Fortunately the Rudy Project Ketyum was one such frame, so I've been wearing those for almost a decade now.
