These ones - black frame, prizm rose lens: http://www.oakley.com/en/a-frame-2-0-prizm/product/WGOO7044PZ
Bought these about 10 days ago on a flat light day when I was traveling and my usual Rx sunglasses were not cutting it. Used two days, a total of 6 - 7 hours. Great high-contrast lens for low light conditions, but they don't fit over glasses which I need to see my watch, maps, phone, etc. Now that I'm home and have my old pair that fits over glasses, time to pass these on.
