Technology beyond the naked eye
Serengeti lenses achieve such a high level of acuity because we only use the finest materials available. And the process by which Serengeti develops their lenses gives them exceptional color and contrast enhancement.

Serengeti's High Definition Lens
Serengeti's proprietary Spectral Control (TM) lens system provides contrast and color enhancement by selectively filtering certain colors from the visible light spectrum. This allows the most optimal colors through, creating an effect where colors are crisper and images are clearer, making it the ultimate high definition view.

Bright or Shade
Serengeti's exclusive photochromic lenses automatically darken in bright sunlight to give superior definition, while they lighten in overcast or shade conditions for extra contrast. And since the technology is infused directly into the lens, it will never wear off or out.

Block the Blues
Blue light waves cause a phenomenon called "blue blur", which occurs when they scatter off dust and moisture particles in the air and, essentially veil glare. Serengeti lenses block 95% of blue light, virtually eliminating the eye strain and fatigue blue blur can cause.

UV Protection Goes Beyond Standards
The government and commercial bodies have set standards for UV protection in sunglasses. Then there are Serengeti's standards. They're like yours standards. They go beyond the basic level of expectation, eliminating virtually 100% of UVA and UVB rays. The Serengeti lenses also feature an anti-reflective coating on the back side to block additional glare and reflections.

Eliminate the Harsh Glare
Glare is inevitable by-product of light rays bouncing off reflective surfaces. But Serengeti's polarizing film removes glare as an uncomfortable factor in driving, and the eye fatigue it can cause.
