A little brother to Costa’s Rincon frame, Rinconcito blends West Coast style lines and edgy curved temples. This medium style, named for the iconic Southern California right point break, features bio-resin construction, polarized 100% UV Protection Lenses, integral spring hinges, and Hydrolite® nose and temple pads. Costa 580® lenses ,which are premium polarized lenses for 100% UV Protection, are mirrored. Costa 580® lenses were designed by in-house light spectrum experts to enhance colors because standard sunglass lenses fell short. The lens' multi-patented technology manages light by: Absorbing Harmful High-Energy Blue Light (HEV) Enhancing Reds, Greens, and Blues Filtering Out Harsh Yellow The sunglasses have a C-wall coating for extra scratch resistance and a repelling water barrier. Reasonable offers accepted. Bought for my husband but did not like them so they were worn about 2 weeks. There are no scratches. His loss is your gain!!! The Costa cloth wipe and case are included.
