So, what is important is what sort of exercises are being used. From the paper, the types are
1. 3D visual training combined with ciliary muscle exercise training
2. Massage (point, eye muscle, head and neck, facial massage roller, automated eye massager)
3. Dazhui vibration (looks like acupuncture)
4. Auricular plaster therapy (some sort of acupuncture using magnetic seeds applied to ear)
5. Badminton training
6. Yoga eye therapy
7. Eyesight gymnastics with physical exercise for health maintenance
First of all, it would be reasonable to concentrate on the interventions where there is a plausible causal model. Should 1 and 7, and maybe 6 (depending on what exercises are being done) be looked at more carefully?
Be being a mere physicist cannot read the forest plots in Fig 2, to determine which of the studies had some positive effect. Can someone else do that?
I can't seem to find any studies with where significant amount of time are (at least 30 min daily) exercises like a simple focus distance changes. Do they exists?
Exactly. If I were to design eye exercises that had some causal effect on either preventing or reducing myopia, it would be very disciplined focus exercises. Likely customized to the person's current myopia level.
I asked a similar question last week, and someone answered [1] with some proposed resources, the first of which looks reasonable. No scientific studies though.
It's somewhat surprising that no quality scientific studies like this seem to exist. I understand that, to our knowledge, exercise can't influence the length of the eyeball, but some well-conducted studies to test that would still be nice.
