This works for some people, not all. Reasons are unknown. Nevertheless, the EndMyopia "eye hacking" community has a wealth of empirical information about vision therapy, otherwise only available from very expensive vision therapists and specialist ophthalmologists. It requires an order of magnitude more effort/time than blindly following the guidance of random local optometrists. Even if you don't apply the methods directly, you can become a better educated consumer of professional eye-health services.
While the market for myopia is large and growing, the market for presbyopia is almost 100% of the HackerNews community. Similar techniques apply, in the face of sizable economic incentives to promote expensive progressive lenses. The advent of online glasses offers more options, e.g. dedicated computer glasses for a fixed focal plane, ChemistriE magnetic clip-ons.
In an industry which spends many hours daily using eyes for closeup work, "eye fitness" offers observable returns on vision literacy.
