The optics lived up to the maker's claims. My vision was quite sharp with no distortion anywhere. Best of all, they were extremely comfortable. Even after riding with them for 16 hours, I could not feel them. In fact, I frequently forgot I was wearing them. The color accuracy was excellent, but I eventually bought another pair in the rose-brown shade and prefer that because it better highlights the red and orange objects and lights that frequently distinguish hazards. The first pair had the larger (Argento) lens size, and I literally could not see the edges and often had to touch them to make sure I had them on. The second set, the Azzurro style, had a smaller lens, so I can make out the edge at the top if I look up hard. You need two hands to put them on because you need to spread the sprung temples, but if I'm riding with them at dusk, I can easily pull them off one-handed and tuck them away.
