Photochromic Sport Sunglasses F325
Photochromic antifog sunglasses F325 by Bertoni Italy:
Frame material: TR90 ( 70% Carbon-30% Nylon ).
Frame color: silver gradient to shiny white (F325CR) or carbon painting (F325D).
Lens color: photochromic antifog from clear to grey.
The temples are made in dual-injection, that makes them particulary strong without losing flexibility.
With the increasing and the decreasing of the exposure to UV rays, the photochromic lenses tend to become dark or clear automatically, always ensuring an excellent visual performance. These lenses are made in anticrash polycarbonate, to protect the eyes, in sunny days and in low and medium brightness conditions. In addition, they are treated with a special resin that can disperse the condensation that forms on the surfaces of the lenses in the transition from hot to cold.
The reaction time of the photochromic lenses is very fast: only 8 seconds to go from clear to dark, and 35 seconds from dark to clear.
The frame is made of non-deformable nylon, a plastic material with high impact resistance.
The lenses are interchangeable so easy to be replaced.
Suggested Sports: Motorbike, cycling, ski, running and free flight.
