ALTERA® STEALTH EYEWEAR
Everything starts from a necessity.
Altera® creates Stealth, high-performance eyewear collection designed for multi disciplined sports. The frames incorporate aerospace-inspired leading edge design. Conceived to fit various designs — differing in shape and lens treatment, they provide multi-sport athletes with advanced, highperformance technology. An additional design makes it possible to fit any prescription lenses, by integrating the innovative Kinetic System, which can adapt a 6 base frame into a 4 base frame.

• ANTI-REFLECTIVE COATING – to reduce reflective light;
• HYDROPHOBIC COATING – to make the surface water-repellent and prevent dust particles from clinging to the lenses;
• OLEOPHOBIC COATING – easy-to-clean lenses;
• SEAWATER – to prevent damages from salt water.

SAFETYBUMPER

The Kinetic System can adapt a 6 base frame into a 4 base frame, making it possible to center prescription lenses, while providing the comfort of the 6 base frame enveloping design.
