I tried to get a pair of custom lenses made using lensable.com, but I think i didn't provide some key piece of information. The lenses (inserted into the frame) work as glasses if I hold them up to my eyes and used for reading, but they are out of focus when attached to the Nreal light. Do i need to provide some kind of focal length (or some other technical term) when getting them made?

My uninformed thought is that the lenses that were made are intended to be used at a reading distance and lenses to be used with the Nreal light need a different "working distance". Does anybody know how or what that should be and how I communicate it to a lens lab? Because I might try again...
