What's your budget? As for reflective lenses, they are excellent for bright days, but are really poor the second a cloud covers that sunlight. Ideally, you either want multiple goggles with different shades of lenses or extra lenses. I prefer buying multiple goggles as you can find many at a cheaper price than a brand new pair of lenses. That way you can also have multiple brands and styles without the need for swapping lenses out. Although if you have Smith I/O, the lens swap is easy peezy.
If you want an all around lens for now, you should take a look at the lens' light chart and look for one that transmits around 50% of the light.
Also, Spherical lenses are going to offer the clearest and most peripheral range of vision over flat lenses like the Anon's that was posted above. However, spherical lenses will cost you more most of the time (there are always sales).
