Mirrored sunglasses dazzle onlookers with their high-gloss reflective optical coatings, dubbed a flash coating or mirror coating. Worn by vision-seekers who don't want the world to see their true colors, these trendy shades often come with lenses that add a warm brown or cool grey tint to an already stealthy appearance. The mirror coating boosts visibility for thrill-seekers facing conditions as challenging as desert sandstorms, snowy mountain ascents, or scorching high-altitudes – conditions where ordinary sunglasses would leave wearers in the dark. What's more, mirrored sunglasses operate on a one-way principle: no matter how intently someone gazes into their lens, not even they will ever get a clear view of what's reflected back. Uniting police officers in style throughout the United States, these versatile shades have earned a colloquialism that's all too fitting – "cop shades". Popular fashionistas love mirrored sunglasses because they can rock them with ease, combining dual lenses in stylish metal frames or Wraparound sunglasses – smooth, single, semi-circular lenses that completely cover both eyes and wrap elegantly around the contours of their face. Wrapping this all together is a simple, sturdy frame that houses everything with an equally durable piece of plastic providing support beneath the nosepad, safeguarding each look as carefully as it conceals its owner's true identity from any curious bystanders who may happen upon them while cruising the high-octane world of extreme sports. But there's something even more striking – an innovation that leaves traditional reflective coatings looking antiquated in comparison. Simply layered one at a time to produce a mesmerizing sheen, modern mirror coatings can now achieve far superior protection against damage or decay, making them all but impenetrable in corrosive environments like saltwater where anything less might simply wither away within weeks. So just how does it get made? Easy - using sputter deposition or other clever processes that expertly prepare metals like titanium, chromium and Nichrome by carefully plating them on to make this highly sophisticated reflective mirror shine like new for many years yet. The process isn't a world away from its humble antireflective cousin: applying several precise alternating layers, the first being some kind of thin film metal - typically anything less than ten nanometers thick – gives us that radiant appearance people want today!
