I just recently picked up a pair of the photochromic Oakley EVZero blades. They are look clear in low/no light conditions. They don’t get exceptionally dark in bright light, but they absolutely get dark enough to avoid any sort of eye strain/squinting, I was not expecting to enjoy them as much as I do. The only downside is that when they are clear they don’t look quite as good as a real mirrored lens, but it’s a small price to pay for how well they work.
