Cloudstory PeakVision III — Photochromic Sport Sunglasses

The Cloudstory PeakVision III is engineered for athletes and outdoor enthusiasts who refuse to compromise between performance and visual comfort in changing light conditions. The photochromic NXT polymer lenses transition from light amber indoors to deep smoke Category 3 outdoors in under 15 seconds, reacting to UV intensity rather than visible light so they darken even behind automotive windshields. The wraparound frame is constructed from TR-90 thermoplastic, a material used in military optical equipment for its near-zero thermal expansion at temperatures from -40°C to 80°C — ensuring the frame never warps during desert heat or alpine cold. A Megol rubber insert runs along the inner temple and nose pad contact points, creating a friction grip that intensifies when wet, keeping the glasses secure during high-intensity runs, cycling sprints, and water sports. The eight-base curved lens geometry maintains a 15 mm eye-to-lens distance that eliminates peripheral distortion at extreme viewing angles. Ventilated temple arms channel airflow to prevent heat buildup behind the ears. The frame accommodates optional prescription insert clip for athletes requiring corrective lenses. Impact-resistant to ANSI Z87.1 safety standard. Hydrophobic lens coating repels rain, sweat, and water spray. Lens width: 70 mm. Bridge: 16 mm. Temple: 130 mm. Weight: 26 g.
