Given that similar claims have been around for a long time and it still lacks published results, I feel people have reason to be skeptical.

I wonder if this "training programme" could be implemented or tested using a VR workspace and varying the (virtual) distance of the working field while adjusting size so that it remains clear. The virtual environment could be finely and dynamically adjustable (as opposed to having to change lenses) and progress could be measured in a consistent environment.

On second thought, if that worked, the Apple Vision Pro might sell some additional units.

China, which has extremely high myopia in its student population, decided to tackle the problem top-down by reducing the amount of homework and forcing kids to play outside. They have some success: https://pmc.ncbi.nlm.nih.gov/articles/PMC9412110/

The claims have been around a long time, but how many people actually follow the guidelines? There are lots of stronger factors preventing people from doing it: economic unrest, smartphones, fear of outdoors and pollution, stronger emphasis on education, etc.

By the same token, doctors claim we can address heart disease and obesity with exercise and diet, but things don't seem to be getting any better.

Anecdotally, after two years of working indoors every day, when I left my tiny apartment only to walk to the store, I had a career change and I had to see an optometrist who prescribed me glasses and insisted on not ignoring this because it's serious enough. I skipped getting glasses and started working outdoors (a high reach telescopic forklift operator). When changing employers only three months later I once again had to see an optometrist (a different one) and I had half of the myopia I had earlier and no recommendation for glasses.

Viture headsets include myopia adjustment up to -5 diopters.
