The other option I haven't seen used may be to dark tint one lense. As I understand it, the eye that has the best vision will be dominant. If light is cut by a large amount, it should fool your brain into making the opposite eye dominant.

I think it would be worth trying, as the benefit may be better field of view.

It should be simple to stop by an auto window tint shop and ask for some small pieces of tint film. You'd want to cover the entire lense, I would think.
