> the eyes require exposition to the sun to produce locally vitamin D to form themselves

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.
