Charles, you obviously have some background in Optometry -- right? Do you care to share it since the rest of us are mere consumers? Your experience with CRT, does it include the more recent products/processes, or is it based on the processes that date back to the 60's? The reason that I ask is that my (layman's) understanding is that the earlier attempts at CRT (aka: Orthokeratology) were limited by the hard lens material that could only be worn during the day when awake. The current products/process allow the lens to be shaped each night so I would expect the results to be more consistent then if a person was wearing the lenses for a day or two and then skipping a day.
