Reedmace w/ clear frames- Prizm Rx color selection is lousy

[Bagofchips]

This is a pretty narrow question but often the insight here is far better than Oakley customer care (whose answer was basically “just because”).

If you try to build some Reedmace prescription starting with the frames, there are almost NO Prizm colors available. Other frame colors in Reedmace or other models with clear frames don’t have this limitation.

Anybody know why? The workaround is a pain in the ass: buy the clear frames w/ no prescription then swap the Rx lenses outfitted on a different Reedmace frame color.
