Description:

There's no such thing as an average day for your eyes. Light changes continually from sun-up to sundown. No matter what the weather may be, your eyes are constantly exposed to lighting conditions that strain and fatigue. Only one brand of sunglasses offers the ultimate protection, Serengeti. The unseen science behind Serengeti lenses is the most advanced in the history of eyewear. Road, water, beach or backcountry, Serengeti's Ronan sunglasses are ready for the adventure. A sleek design is joined by the rugged durability of an acetate frame and the fantastic clarity of optical glass lenses.

The lenses change as quickly as the scenery. When you're on the road, the light can be unpredictable. Your eyes demand a level of attention and care that only Serengeti photochromatic technology can provide. The molecules inside the lenses react to light - causing them to lighten or darken automatically. You'll notice your never feel strained or tired because the lenses are doing a lot of the work for them. The result is a crystal clear clarity that produces vibrant colors in all that you see.  Since the technology is inherent in the glass, it never wears off or wears out.

Features:

• POLARIZATION: When normal, parallel rays of light bounce off surfaces like windshields, windows, water or ice, they create random light waves. These reflected light waves produce glare that irritates your eyes. Working like microscopic Venetian blinds, the polarized filters in Serengeti's lenses “organize” the light, eliminating glare and reducing eye fatigue.

• PHOTOCHROMIC:  Serengeti's exclusive photochromic lenses constantly adjust to changing light conditions. Activated by the amount of ultraviolet light in the atmosphere, the lenses darken in bright sunlight and lighten in overcast conditions. And because the technology is engineered into the glass, it can never wear off or wear out. With Serengeti you're always wearing the right lens, no matter what the conditions.

• PREMIUM UV PROTECTION:  Every day your eyes are bombarded by potentially damaging ultraviolet rays from the sun. Many sunglasses filter some UV light, but Serengeti lenses block virtually 100% of UVA and UVB rays, exceeding all government and commercial standards. Lenses also feature an anti-reflective coating on the reverse side to block glare and back reflection.

• OPTICAL GLASS:  Made from distortion-free, precision ground and polished optical glass, Serengeti sunglasses give you the clearest image available. Scratch resistant and chemically tempered for strength, each and every lens is drop ball tested with a steel ball to ensure maximum impact resistance. With proper care, Serengeti lenses can last a lifetime.
