the taller lens leads to increased viewing range in the upper peripheral region of your vision. Initially, this was an aspect that I didn’t anticipate noticing on my runs. Once I got out on the road however, it was very apparent — instead of my eyeline hitting the top of the frame when I glanced forward, I’d hit nothing but the lens. The taller lens, paired with the wrap-around design, actually made a much bigger coverage difference than I thought it would.
