The Revo lens was originally developed by a NASA optical engineer during a research programme in the 60's.To begin with the Revo surfacing technique was used to coat orbiting spy satellites optical lenses to protect them from the suns damaging UV rays. It was only later that the same engineer came up with the idea of applying the same multi-layer coating to sunglasses.
Revo lenses are now available in many fashion and vintage sunglasses with or without polarization. You see them on vintage Wayfarer sunglasses, aviator sunglasses and sport sunglasses. The multi layer coating reduce lens glare and greatly reduces the UV rays which these days it is extremely important to protect your eyes against. Revo sunglasses have also become a desirable in fashion accessory as they look amazing and the cost is significantly more affordable than they used to be. Technology now exists to allow easy fabrication of the Revo lens. You can find them in yellow, orange, green, blue and even silver in many different shapes and designs.
The Revo vintage style sunglasses look so good that when ever you have them on you will be turning heads and you will look and feel so cool.
