We wholeheartedly believe here at Goodr that golf is fun. Why does it have to be so serious? Lighten up! For that reason, we have dubbed our golf-specific lens "Flamingo Eye(TM) Technology." All the HD contrast and performance without any of the self-importance. No Slip: special grip coating to help eliminate slippage when sweating. No Bounce: the frame is snug and light-weight with a comfortable fit to prevent bouncing while running. All Polarized: glare-reducing polarized lenses and UV400 protection that blocks 100% of those harmful UVA and UVB rays.
