I wouldn't recommend carrying them with you. I did that a few years back when I was struggling with my crowbars and variable weather. I broke a few pairs, even in my backpack. Smith does sell a hard case for goggles which I use if I'm wearing my pack.
Your eyes will adjust with time, but I personally would want to see terrain as best as possible. I ended up getting the IOx and their photochromic lens. Good luck.
