The Costa 400 Howler Sunglasses are available in two different lens types—LightWAVE glass or CR-39® scratch-resistant plastic. Both lens materials are 100% polarized, 100% UV protected and offer heightened clarity, contrast and unbeatable optical definition. Manufacturer's lifetime warranty.

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 a fully functional, lightweight alternative to glass. This lens type offers all the same advantages of the LightWAVE glass but in a more affordable material.
