ZIPPO OS-G1-BLK photochromic

ZIPPO OS-G1-BLK sunglasses for adults protect your eyes with a UV400 filter that blocks both UVA and UVB radiation. Photochromic lenses automatically react to light intensity, changing their tint from clear to smoky. The rectangular frames features a Night Fluo fluorescent effect, so they glow in the dark after exposure to light. Shatterproof polycarbonate lenses help reduce eye fatigue and improve colour perception.

Lens and frame technology

The heart of ZIPPO OS-G1-BLK sunglasses lies in their photochromic lenses. These lenses react seamlessly to the amount of ambient UV radiation and automatically adjust their level of tint. They remain clear indoors or in low light, while darkening to a smoky shade in direct sunlight. The polycarbonate lens material is highly impact-resistant and prevents the formation of sharp fragments in the event of damage. The Night Fluo finished frames fluoresce in the dark after exposure to daylight or an artificial light source.
