Advisory Board Crystals eyewear, handmade in Japan. 

We designed these glasses from the ground up. Taking into account every aspect and detail. We worked with a former engineer who now does eyewear in Japan. He is obsessed with the weight ratio of how the glasses feel and sit on your face. Almost a year of development, these are our standard studio frames. Meant to be worn at any time, we used a state of the art photochromic NXT lens with inside and out AR coating which allows for the lens to get darker in the sun, and shift to a lighter green tint when indoors. Other details include old school construction with custom gold rivets, embossed gold logos and text, and laser etched Abc. on the lens. Please allow 7-10 days for shipping.
