When it comes to sunglasses, the durability of the lenses is a crucial factor. Costa, a popular brand known for its high-quality fishing and outdoor eyewear, offers two types of lenses: 580G (glass) and 580P (polycarbonate). Understanding the differences between these lens options can help you make an informed decision about which Costa sunglasses are best suited for your needs.
Costa 580G Glass Lenses: Scratch-Proof Protection
Costa’s 580G glass lenses are designed to be highly scratch-resistant. These lenses feature encapsulated mirrors between the layers of glass, making them virtually impervious to scratches. The glass construction also provides superior optical clarity, allowing more light to pass through without scattering or absorption. While glass lenses are slightly heavier than polycarbonate, Costa has engineered them to be 20% thinner and 22% lighter than traditional polarized glass lenses, ensuring a comfortable wearing experience.
Costa 580P Polycarbonate Lenses: Durable and Impact-Resistant
For those seeking a more lightweight option, Costa offers 580P polycarbonate lenses. These lenses are highly durable and impact-resistant, making them a suitable choice for active outdoor pursuits. While polycarbonate lenses are not as scratch-resistant as glass, Costa’s 580P lenses feature a C-Wall Molecular Bond, which enhances their scratch-resistance compared to other polycarbonate lenses on the market.
