AS SMART AS THEY ARE COOL
The Serengeti LUPTON men’s sunglasses with PhD™ 2.0 lenses are a game changer in eyewear. Built with environmentally-conscious nylon, the LUPTON are zero-waste nylon sunglasses that also feature soft temples and rubber on nose pads for comfortable, all-day wear. Putting on a pair of these is the smartest move you’ll make all summer.
Category 3 to 3 in mineral lens.
Category 2 to 3 in PhD™ 2.0 lens.
Very bright light conditions.
The non-polarized lens is ideal for Driving and Everyday use.
The polarized lens is ideal for boating activities.
Available in non-polarized and polarized ultra-light mineral and PhD™ 2.0 lenses.
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.
THE PERFECT BALANCE OF VISUAL AND PHYSICAL PERFORMANCE.
As quality and perfection are key for us, we dedicated this remarkable lens to our Sport collection.
Built with NXT® technology and made from Trivex material, the PhD™ 2.0 lens is extremely light and thin, 75% lighter than glass, ultra-flexible, while being highly impact and temperature resistant.
In fact, to begin with, Trivex material was used by the US military for fighter jet canopies and helicopter windshields. It has required 12 years of development: 10 within the military and 2 years for adaptation to the optical sunglass lens market.
This lens also offers a high optical clarity and avoids any distortion.
The PhD™ 2.0 features hydro- and oleophobic front-side coatings, which help repel water, fingerprints and debris.
The highly durable backside anti-fog treatment enables perfect vision and performance whatever the activity.
Molecularly infused in every Serengeti® lens
ADAPT TO LIGHT
As 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 CONTROL® TECHNOLOGY
Molecularly infused in every Serengeti® lens
MANAGE THE LIGHT
Specific 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 our biological clock. However, it is also a high-risk factor for age‑related macular degeneration (AMD).
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.
It enhances a natural color balance and improves contrasts and perception by acting like a “HD” visual equalizer to achieve the perfect mix of colors across all conditions. It selectively manages light wavelengths, distinguishing reds, greens, and yellows.
Landscapes that would be washed out, dull or flat with other lenses become defined, vibrant, and vivid — while your eyes remain cool and relaxed.
CONTROL THE LIGHT
Whether you’re in a high- or low-glare environment, you deserve lenses that give you the ultimate glare protection and with it, uncompromised clarity.
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.
When glare reflects off the road, water, snow or flat areas, parallel light rays can pass through unhindered, while distracting perpendicular light is reflected.
It offers UV protection up to 400nm.
This polarization technology relieves eye fatigue and impeded vision by eliminating disruptive glare. It also allows you to experience absolute clarity, revealing elements that you couldn’t see before.
Some products feature non‑polarized lens option.
MADE IN ITALY
Grilamid BTR XE 4010, the polymer’s scientific name, is a sustainable substitute for TR90. It is extracted from Castor Plant but offers the same characteristics as TR90 Nylon (durable, flexible, lightweight, can bend, less likely to break) without requiring the use of petrol.
The castor oil seeds contain a large share of oil which can be modified to create primary raw materials for various bio-polyamides.
With the partially bio-based material Grilamid BTR, an amorphous transparent bio-polyamide, the reduction in CO2 emissions compared to traditional transparent polymers, such as PMMA or PC, is more than 40%.
