Need to give your Arnette Shoredich AN4255 sunglasses a new lease on life? These Mryok replacement lenses are a premium option. They're specifically designed to fit that model and come in a Polarized Silver Titanium tint. Mryok is serious about quality: these lenses are made from injected molded polycarbonate that's thicker and stronger, exceeding ANSI Z87.1 high-impact resistance standards (so they're safe). They're 100% UV protective, of course. The big features are the advanced coatings: they have a super hard 'Plus+' anti-scratch coating that reportedly lasts 3x longer than traditional lenses, a nano-coating that repels water, oil, sweat, and dust, and they're even resistant to seawater and soapy water - great for beach days. Being polarized, they cut glare and enhance contrast, making everything look clearer. The light transmission is about 18% for a neutral view. They also have XELD® taper correction and AR coating for superior clarity. Mryok backs them with a 1-year warranty against defects and promises efficient customer service. If you want durable, high-performance replacement lenses for your favorite frames, these are a solid choice.
