Costa Del Mar review

Costa Del Mar suits glasses wearers who fish, boat or spend long days near water and have a mild prescription. Its prescription page offers Costa frames with the brand's 580 polarized lenses in single vision or multifocal designs, adding 100% UV protection, C-Wall scratch resistance and a backside UV anti-reflective coating. On November 13, 2026 it listed styles such as the Suenos at $249.00, the Broadbill II at $285.00 and the King Tide 8 at $382.00, with a 30% off promotion on prescription sunglasses. Returns are free within 30 days, and the site accepts vision insurance and FSA/HSA benefits. The main limit is the online prescription range: Costa only fills prescriptions from -5.00 to +1.25 online, and its 580G glass lenses require a visit to an authorized prescription dealer. You also email your prescription within 5 days after checkout rather than uploading it in the cart.
