Prescription sunglasses with photochromic lenses. (Under $200 at Costco if you can find a sunglass frame there that fits you.) Like most people I had written off photochromic lens technology decades ago (too slow to respond to light changes). But the current generation is much better (they've gone through something like eight of them by now) and I do a lot of utility cycling in the Pacific Northwest. And that means that you can go through everything from bright sunlight (OK maybe not bright by most peoples' standards :-) to overcast to darkness in a trip to the grocery store. Having a single pair of glasses that can take me through all of those conditions is surprisingly liberating. One limitation to be aware of is that the material in the lenses responds to ultraviolet light. Which means that they really only work outdoors. So you're still going to need a separate pair of sunglasses for driving.
