I just picked up a pair of Smith IOXs that came with a Green Solex and a Blue Sensor lens. I was impressed with the peripheral vision. Forcing my eyes all the way to the right and left (to the point of being painful), there is only half a pinky finger width of frame visible. The shortcoming on the IOXs in my opinion is the downward peripheral vision. Definitely not the best if you have a big nose can can't push them down without closing off your nostrils. Awesome lenses though and comfy as hell.
