BluBlocker™ high resolution lenses block 100% of UV light and 100% of blue light.  As a result, you will not squint on a sunny day at the beach, on a hike, or on the lake.  Crystal clear BluBlocker™ vision is unique to BluBlocker.  This is what the legendary BluBlocker reputation was built on.   The ultra-lightweight nylon frames are comfortable and don't slide or move on your face.  These are great for being active, playing sports, driving (sunny and cloudy days), and lounging poolside.  Drawstring pouch included.
