Winona is the new chunky acetate frame, combined with mineral lenses, of the Serengeti Main Line Collection. Its acetate construction plays with proportions, proposing a bold front while showing an extreme fineness when viewed from the side. Winona's strong personality is also highlighted by its angular profile, providing an assumed fashion look.

Features:

• Drivers Cat 2 to 3: Ideal for driving and everyday use in overcast to medium light conditions. Available in non-polarized and polarized ultra-light mineral and PhD™ 2.0 lenses. Absorbs 77% to 91% of the visible light, and blocks 89% to 96% of the blue light, according to the lens. The amber-colored Drivers lens naturally amplifies contrast and definition. This lens provides technicolor sensations of warmth and is ideal for driving because it enhances colors and contrast, while lightening and darkening to provide optimal light transmission in any condition.
• Ultra Mineral Lens: Our mineral lenses are made with borosilicate optical glass, from Corning®. A full 20% thinner and lighter, our 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 Technology: Serengeti® Photochromic lenses are activated by the amount of UV radiation in the atmosphere and engineered to transition from light to dark, gradually.
• Spectral Control Technology: Spectral Control® Technology filters up to 96% of blue light, allowing only the beneficial and regulating turquoise blue light to pass through, to reduce blue blur and visible noise. This protects your eyes from aging and damage to preserve your sight perfectly.
• Polarization Technology: Our polarization technology eliminates 99,9% of disruptive glare from the four types of glare: distracting, discomforting, disabling and blinding. This ensures, therefore, no more reflection from: vehicle headlights, intense lights, shiny surface reflections and the everyday outdoors.
