The VZUM ™ F-LENS is an interchangeable photochromatic lens that adapts itself to the intensity of the light present in the environment. It automatically changes colour, shielding off harmful UV rays of any sort.
Their temporary transformation takes place in a short period of time but it is, nevertheless, gradual and independent of any atmospheric factors.
The optical strain is therefore reduced to a minimum and the lenses remain active even on a cloudy day.
Optimal photochromic control is:
– Fast kinetics: activation and fading speed
– Large photo range: from cat. 0 (Tv 86%)
– Durability: long term resistance to radiation
Photochromatic lens. Guarantees excellent visibility, both in poor and intense light conditions.
CAT 0 ÷ 3 | TRA 23% ÷ 80%
