INCLUDES: BLUE LIGHT BLOCKING (HEV coating) Optical grade CR39 lens Superior hard coat for anti scratch durability Anti-reflective coatings to mitigate reflections and glare. Super hydro-phobic and oleo-phobic coatings for anti smudge Handcrafted acetate designs utilizing state of the art CNC and finishing for fit, function, and durability. Possibly the one model that has the largest audience when it comes to fit. It’s like the elastic waist pant of eyewear…which is really degrading to the Miklos, but we’re just trying to make a point. People with larger faces like the thickness of the frames, and how solid they feel. Customers with smaller faces also like wearing a frame that stands out. Just depends on what you’re into. We’ve also taken liberty to engrave “Port” over the left eye, and “Starboard” over the right eye. It’s a boat thing. Not a yacht thing. All Caddis readers block blue light. Our included HEV coating blocks harmful high energy light screens emit. We're pro cool shit you're doing on your screens. We're anti eye strain, headaches & disrupted sleep. Block. Blue. Light. Now.
