With the new Lambda Technology, Rodenstock promises sunglass lenses with high precision and optimum contrast power. Most regular sunglasses today reduce light by up to ninety percent. When light is reduced, we experience less detailed vision. Lambda Technology is designed to increase contrast with colors that enhance both depth and detail. Rodenstock’s color contrast index allows us to select the most suitable lens. The colors in Lambda Technology sunglass lenses are finely tuned to optimize contrast. The Rodenstock color contrast index helps to find the sunglass lens color that best suits a person’s needs, using a method that relates to different color perceptions and contrast levels. Contrast is created by reducing the blue light passing through the lens. Due to its short wavelength, most of the scattered light is blue light. Since scattered light carries no visual information, blue light reduces visual acuity. Sunglasses lenses based on Lambda Technology provide sharper vision because they minimize the amount of blue light passing through the lens. In addition, sunglass lenses made with Lambda Technology help to reduce glare in sunny weather by blocking reflected light, thus further improving visual acuity.
