Is there such a thing as too much blue With ‘Rainwalker.’we answer with an emphatic. No. No. there is not. A polarized sky blue lens stretches wide. nearly from ear to ear??if you could somehow wear a perfect. cloudless day. this would be it. The frame and temples get a complementary azure aesthetic thanks to satin metallic blue paint. and everything is finished in a rubberized coating for an unrivaled full-coverage fit and feel. //
