My gf recently purchased a Polished White/Grey Riddle. She already had a Pink Suede/G40 Black Gradient(05-910 ordered from the O site).
Today she asked me to swap the lenses. Everything went ok, until I wanted to put the G40 in the white frame. It just didn`t fit, it wouldn`t pop in at the center.
At a closer look I discovered that there is a minimal difference in thicknes at the top of the frame.
I rushed to my PC, checked out the database, cause my first thought was the grey lens must be asian fit. But bummer! There is no grey asian fit lens.
Both pairs are genuine.
I`m pretty confused... Any suggestions?
Thanks!

The acetate frames are heat-adjustable, so there might be some difference. Run a hair dryer over it and see if you can bend the frame a bit and get the lens in.

No point in doing that it’s a different cut lens even if you get it in with heat i wont stay in for long Just like the crosshair its a differ groove on the lens

Does this mean the riddle lenses are not interchangeable? I will give the hair dryer a try.
Thanks for your quick response!

oakdays is correct, there was a rolling change in the lens cut on the riddle, sounds like you have one before the change and one after.
