I think the best known environmental risk factor (to date) for myopia is lack of intense/outdoor light exposure. The pathway for this is reasonably well understood, namely: lack of intense light exposure leads to lowered dopamine, which is necessary to prevent eye growth, which in turn leads to myopia.
This based on relatively recent evidence, but it is of ...

A systematic review of the side effects of retainers said nothing about sleep related side effects, so they probably are not a significant problem.
