Is this controlled for the partially UV blocking effect of lenses though? I.e. is it the prescription in the lenses that does it or the lack of UV rat exposure?

It has been shown again and again that the eyes require exposition to the sun to produce locally vitamin D to form themselves correctly [0], [1].

Go out and play (no citations needed)!

I don't follow this. The articles use blood serum concentrations of Vitamin D in their methodology, are you saying there is a separate Vitamin D production/concentration in the eye's vitreous?

It is not clear if vitamin D in the blood directly affects the formation of the eye or if the creation of vitamin D directly in the eye because of the Sun exposure do so. Here is an article[0] which is easier to read than a study.

It’s fun that one freak suggests regularly looking at sun (with closed eyes, of course), as one of his therapies for myopia. May be there’s something to it.
