I do not wear glasses, and no longer have my CL, but when I did have it I found it quite useable.
That said, it wasn't quite my cup of tea. Despite liking the overall size of the CL, I found the distortion in the viewfinder noticeable, the finder itself on the cool side (blue tint), and the rf spot not the easiest to line up (small and faint).
My main usage was with a 35mm as a street shooter, so mainly used the viewfinder for framing. Scale focussing eliminated the need to focus with the rangefinder patch
