Serengeti Sassari Sunglasses, Polarized 555nm Blue

You will think the Sassari's were made for you with the new Wire-Flex technology. Designed to bend and contour to your face, the frame technology provides lightweight comfort for every situation. With the most optically superior lens on the market, no image goes unnoticed. All Serengeti lenses offer the latest in photochromic technology, which constantly lightens and darkens throughout the day to ensure you see every detail. As the pioneer of photochromic technology Serengeti leads the industry in creating lenses that adapt to any light condition in any setting. Darkening in bright sunlight and lightening in overcast conditions, photochromic technology allows your eyes to adapt to any light, in any weather. The result is a view of the world so crystal clear, you'll notice natural beauty you've never seen before. Serengeti photochromic lenses are activated by the amount of UV radiation in the atmosphere and engineered to transition from light to dark, gradually. Keeping your eyes and mind relaxed and focused on the road ahead. Energy from UV radiation causes the polarity of the silver salt lens molecules to expand in brighter conditions, creating a denser lens that absorbs more light. In darker conditions, the molecules compress and separate to allow in more light. Photochromic lenses optimize for the environment, providing your eyes with the exact amount of light needed at any time enabling your eyes to discern shapes and colors more quickly while eliminating eyestrain.

Serengeti Spectral Control technology removes wavelengths to give better saturation of what we need to see. Much like an audio equalizer filters sound frequency, our lens fine-tunes and filters shortwave blue light, allowing more red, green, and yellow to pass through. Landscapes that would be washed out, dull, or flat with other lenses become defined, vibrant, and vivid. Traffic signs and signals appear more distinguishable while your eyes remain cool and relaxed. Serengeti Spectral Control technology excels at diminishing atmospheric haze, filtering up to 96% of blue light to reduce blue blur and visible noise, while enhancing contrast and sharpness. Lenses selectively manage light wavelengths, distinguishing reds, greens and yellows, in any light condition. Providing improved depth perception and maximum color contrast. While some blue light (blue turquoise) regulates our biological clock, retina-harming blue-violet light is a risk factor for age-related macular degeneration (AMD). By filtering it out, Serengeti Spectral Control technology helps preserve your sight perfectly.

A headache from glare can ruin your day. With Serengeti Polarization technology, it becomes a thing of the past. When glare reflects off the road, water, snow or flat areas, parallel light rays can pass through unhindered, while distracting perpendicular light is reflected. This allows you to discover more clarity, while living free from glare and eye fatigue. When glare strikes, embedded Serengeti Polarization technology acts like a Venetian blind. While parallel light rays enter each lens, distracting perpendicular rays are reflected. Serengeti polarized lenses relieve eye fatigue and impeded vision by eliminating disruptive glare from: vehicle headlights, intense lights, shiny surface reflections and the everyday outdoors. This polarization technology allows you to experience absolute clarity, while discovering layer upon layer of details that glare would have otherwise kept hidden.

Grinding with diamond wheels. Microscopically infusing technology. 1000°C (1832°F) temperature. If there's a way to make their lenses more optically advanced, Serengeti will find it. 555 nanometers mark the center of light's visible color spectrum, right on the border of yellow and green. This is where the human eye sees best. That's why Serengeti 555nm lens was created specifically for optimal sight in bright climates. In low light conditions, this lens allows more yellow and green to pass through, creating relaxing conditions for the eyes. Because the brain can recognize these two colors most easily, yellow is widely used on caution signs while green on black are used on radar screens, night vision devices, LED displays, and DVD players. Very bright light conditions - ocean, driving and every day.As a beautiful variation of the 555nm, the 555nm Blue features a reflective blue dielectric mirror coating, which offers a category 2 to 3 555nm lens protection that reflects more glare and improves contrast.

Serengeti mineral lenses begin with borosilicate optical glass from Corning, which can withstand extreme temperature changes, allowing the best visual acuity you could ever experience. An anti-reflective coating is added to the backside of the lens, cancelling the scattering light that causes reflective glare. Plus, the lenses are chemically tempered to ensure scratch and impact resistance, then ground to perfection. Every pair of Serengeti mineral lenses is unique and comes to life through an intense hydrogen-firing process. Staying true to Serengeti's commitment to craftsmanship, they always give unparalleled attention to detail throughout every phase of the lens-making process. A full 20% thinner and lighter, Serengeti's Borosilicate mineral glass lenses are finer than any other lens. Produced in the same process normally reserved for ophthalmic-quality corrective lenses, they also provide the best visual optics in the industry. Each photochromic lens passes through a hydrogen-fueled Lehr furnace, which fuses each lens with the Spectral Control technology - with varying temperatures that determine the proprietary lens hue. The Sassari by Serengeti lenses have 25% transmittance lightened lens, 16% transmittance darkened lens, 9% blue light blocked lightened lens and 93% blue light blocked darkened lens.
