Revolutionary advances in lens manufacturing have allowed for extremely detailed customization of the lens surfaces on a case by case basis. These lenses are often referred to as a “digital”, "digital free-form" or "high definition digital" lenses. Compared to the best of traditional conventional lenses of just a few years ago, digital lenses deliver improved clarity, visual comfort and field of view. Lines will appear straighter, there is less wave and distortion when moving your head and the central clear zone… “the sweet spot”… is larger.
Nikon Design Engine
Each pair of Nikon digital lenses dispensed by Westwood Optical are custom designed by a computer in Japan. A range of details such as your lens prescription, frame size, frame shape and fitting characteristics are taken into account. The final design is then sent to Canada for processing by Nikon Lenswear Canada. Nikon refers to this process as the Nikon Design Engine.
