This channel is about threshold prevention of nearsightedness. By "Threshold" I mean you can still read the 20/30 to 20/60 line on your "home Snellen". You might have a -1 or -2 diopter lens - to give you 20/20. Pilots in that range, had SLOWLY gotten back to 20/20 - because they have great persistence, and have no "fear" about wearing a plus. This site teaches you to measure your own refractive state - as part of that recovery effort. There are no "quick fixes" or easy solutions on this Channel.
