When I bought my Radar Lock Photochromic, I was given a 40% off coupon for almost any Radar Lock lens (anything except polarized and photochromic). My intended uses for this pair is basically everyday wear and exercise. I run in the weekends, usually around dusk and the evening. I also don't drive, so I spend a fair bit of time on my feet and in public transportation throughout the day. Given all this, is it pretty much down to aesthetics for my usages?
