The glasses fit my face well - the self adjusting light sensitive lenes are great and go back to near transparent quickly.  The thing I love is the clarity that I didn't have before with cheap range glasses.  With these glasses I can more acurately aim farter out making 15, 20, and 25 yard targets a possibility of getting better consistent targets.... before with the crappy $10 goggles the targets were so blurred I couldn't get consistent groupings past 12 yards - now I'm consistently improving my groupings as I master trigger control and the goggles are no longer my weak link.
