PHOTOCHROMIC
Serengeti's exclusive photochromic
lenses automatically 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.
