ALL POLARIZED: We use glare-reducing, polarized lenses with UV400 protection that blocks 100% of those harmful UVA and UVB rays. ALL FUTURE: A futuristic one-lens frame that’ll convince people you traveled here from the future to warn us about the AI takeover. ABOUT GOODR: In 2015, goodr was created to solve a problem: running sunglasses were expensive, ugly, and over-engineered. To solve this, we set out to design a pair of running sunglasses that were affordable, stylish, and all-performance. And so, goodr was born. BOOM. Problem solved. You're welcome. TAG, you're IT in these purple shield sunglasses w/ half-rim frames & light pink reflective lenses. Channel your inner cephalopod's athletic abilities in these baddies. (Get real, does having eight arms give you an unfair advantage when playing tag?)
