The Costa Fathom 400 Sunglasses deliver unbeatable function, fashion, and value, all in one package! Fathom Sunglasses feature Costa's innovative Hydrolite™ construction with cold-molded frames for the perfect fit; three vents on each side for cool comfort; co-injected temples. In addition to the perfectly fitting, stylish frames, the Fathom 400 Sunglasses are available in two different lens types, LightWAVE glass or CR-39® scratch resistant plastic. Regardless of lens type, every pair of Costa's Fathom 400 Sunglasses is 100% polarized, 100% UV protected and offers heightened clarity, contrast and definition.

LightWAVE glass lenses are 20% thinner and 22% lighter than typical glass lenses but they still exceed federal standards for impact-resistance.

CR-39 scratch-resistant lenses are fully functional, lightweight alternative to glass. This lens type offers all the same advantages of the LightWAVE glass but in a more affordable material.
