We know how myopia works now. Low dose atropine and glasses with fogged edges reliably slow or stop myopia progression. Myopia is not reversible by natural means. Sunlight is maybe related but it is more likely the proven mechanism of near work, specifically keeping peripheral vision in focus which tells the eye to grow longer (there is no brain involvement, the eye does this alone). Myopia discussions are terrible, they are filled with people offering advice and guesses on something they don’t know anything about, and people claiming it’s curable.
