Costa Del Mar makes polarized sunglasses with 580 lens technology, plus prescription sunglasses, optical eyewear, apparel and accessories built around fishing and life on the water.
The first number to watch is $50: Responsible shipping is free at that total and costs $4.99 below it.
Costa sorts its sunglasses by where and how they are worn: shoppers can filter by fishing environment (offshore, inshore or freshwater) and by light, from bright sun to low light and cloud. Collections include the Pro Series aimed at serious anglers, the Del Mar Collection, Untangled and the Pathfinder Series, and many frames are made from a bio-based material. Lenses block 100% of UV light and use a C-Wall coating against scratches, with glass versions offered as an upgrade.
For prescription wearers, Costa offers no-line progressive lenses, Transitions options and readers, and takes vision insurance and FSA/HSA funds. Frames can be engraved or personalized, a Frame Advisor tool and a virtual try-on help buyers compare styles, and the Crew Rewards Program adds member perks. The brand also publishes Costa Stories, a set of articles on fishing trips, safety and gear.
