Serengeti Chadwick Shiny Black Shiny/Light Gold/Mineral Non Pola

A classic masculine design, with angular lines to create a chic frame with a unique character. Chadwick’s frame material is a combination of eco-friendly acetate and metal, added to this winning duo is mineral lens for the ultimate visual experience of the world around you. The engraved metal bridge is the final sophisticated touch to this timeless design. 555 nmCategory 3 to 3 in mineral lens.Category 2 to 3 in PhD 2.0 lens.Very bright light conditionsThe non-polarized lens is ideal for Driving and Everyday use.The polarized lens is ideal for boating activities.Absorbs 79 % to 92 % of the visible light, according to the lens.Blocks 88 % to 96 % of the blue light, according to the lens.555 nanometers marks the center of light’s visible color spectrum, right on the border of yellow and green. This is where the human eye sees best. In low light conditions, this lens allows more yellow and green to pass through, creating relaxing conditions for the eyes, while the light silver metallized mirror coating (available only on mineral lens) reflects glare.ULTRA-MINERAL LENSMineral lenses are made with borosilicate optical glass, from Corning. A full 20 % thinner and lighter, Borosilicate mineral glass lenses are finer than any other lens. Produced in the same process normally reserved for ophthalmic-quality corrective lenses, they provide the best visual acuity you could ever experience.Every pair of Serengeti mineral lenses is unique: each Photochromic lens passes through a Hydrogen-fueled Lehr furnace, which activates the Spectral Control technology - with varying temperatures that determine the proprietary lens hue.They are also chemically tempered to ensure scratch and impact resistance.To complete this unrivalled visual experience, an anti-reflective coating is added to the backside of the lens, canceling the scattering light that causes reflective glare.PHOTOCHROMIC TECHNOLOGYAs the pioneer of Photochromic technology, Serengeti leads the industry in creating lenses that adapt to any light condition in any setting. Serengeti Photochromic lenses are activated by the amount of UV radiation in the atmosphere and engineered to transition from light to dark, gradually.In bright conditions, UV radiation is more intense. The lens molecules expand in size, darkening the lenses. Less light can then pass through.In darker conditions, UV radiation is less intense. The molecules shrink and separate, lightening the lenses. More light can pass through.Your eyes are always protected and receive the optimal amount of light needed at any times and in all weather conditions.You are able to discern shapes and colors more quickly while eliminating eyestrain.SPECTRAL CONTROLSpecific and unique to Serengeti, Spectral Control technology provides you with the ultimate High Definition vision of everything in sight.Blue light is necessary to regulate biological clock. However, it is also a high-risk factor for age‑related macular degeneration (AMD).Spectral
