Costa Del Mar Fernandina 580G Polarized Sunglasses

Shoppers searching for Costa Del Mar sunglasses know the name stands for glass-clear polarized optics built for real time on the water, and the Fernandina carries that reputation in a narrow-fit frame designed to sit close and secure on smaller face shapes. Island Water Sports carries the Fernandina with genuine 580 lens technology, the polarized glass Costa is known for wherever glare off open water is a problem.

Frame and Lens Details

• Lens material: Polarized Plastic (580)
• Frame fit: Narrow
• Prescription ready: Yes
• Frame width 132.7mm, bridge width 15.8mm, lens width 57.3mm, lens height 43.0mm, temple arm length 130.0mm

These are the same measurements Costa publishes for the Fernandina model, so anyone comparing fit across the Costa lineup can size this frame against others they already own.

Who This Frame Fits

The narrow frame fit means the Fernandina is built for a smaller or narrower face profile, one of the three fit categories Costa uses across its entire sunglass line alongside Regular and Wide. Costa's own guidance is that fit comes from the combination of overall frame size and how the hinges and temple construction sit on the head, not just one measurement, so trying a narrow-fit frame on is the surest way to confirm comfort.

Everyday and On-the-Water Use

Because this frame is prescription ready, it can be fitted with corrective lenses for anglers, boaters, and beachgoers who need sharp polarized vision without switching glasses on and off the boat. Polarized lenses cut glare bouncing off flat water and sand, which is exactly the kind of environment South Florida shoppers are wearing these frames in day to day.

Care and Fit Guide

Costa recommends using its fit guide, Narrow to Regular to Wide, to select a frame that will actually stay comfortable through a full day outside rather than pinching by the afternoon. Store polarized lenses in a protective case when not worn and rinse saltwater spray off the frame and lenses to keep the hinges moving freely.
