Julbo Frequency Reactiv Light Amplifier sunglasses matt black/gray/multilayer red (J5673314)

The Julbo Frequency Reactiv Light Amplifier matt black/grey/multilayer red sunglasses provide advanced eye protection in dynamic lighting conditions during cycling and outdoor activities. This model features modern photochromic lenses that automatically adjust the tint level across categories 1, 2, and 3, ensuring optimal visibility in changing sunlight.

Reactiv Light Amplifier Lens Technology

The photochromic lenses in the Julbo Frequency Reactiv Light Amplifier offer a light transmission range from 17 to 75%, allowing smooth adaptation to current weather conditions. The built-in UV filter effectively protects the eyes from harmful solar radiation, while the advanced Light Amplifier technology enhances contrast and sharpness in variable light. The absence of a polarising filter ensures undisturbed perception of details on asphalt and cycling paths.

Materials and Construction Details

The frames are made from high-quality RILSAN material, known for its lightness, durability, and resistance to sweat and UV exposure. Thanks to the innovative Grip Nose bridge, the sunglasses remain stable during dynamic movements, and the Rilsan Clear® system supports the durability of the construction. Non-replaceable lenses and a specially designed frame profile emphasise the sporty character and reliability of the model.
