Swinging

Swinging is one of the exercises advocated by the Bates Method.

There could be some rationalisation for it : by allowing the Visual cortex to see different focal planes moving relative to each other, it gains information about the relative distances of those planes, which it would not otherwise have (due to Myopic blur). It might be able to use that extra information in some useful way.

It would do no harm to give it a try while you're looking out the window anyway, while observing the 20-20-20-Rule. Let us know if you find it helpful. If nothing else, it will give the neighbours across the road something to talk about.

You could try chanting a mantra at the same time. I can't think of a rationalisation for that, but it might entertain your cat.

The Myopia is Mental method extends the idea of swinging to make yourself aware of objects moving relative to each other as you walk. That is not dissimilar to the rationalisation above - it could conceivably give some additional depth information.
