Sports Polarized Colorful Outdoor Transition Photochromic Cycling Sunglasses

⚡ Polarized & Photochromic Hybrid  

Blocks 99% horizontal glare while auto-adjusting tint intensity—40% faster light adaptation than standard transition lenses. Ideal for sudden tunnel exits or forest canopy transitions.

🚴 Cycling-Optimized Design 

• Wraparound Shield: 180° peripheral vision coverage, critical for spotting road hazards during high-speed descents.
• Anti-Slip Silicone Grips: Zero slippage at >40km/h winds (tested in coastal cycling conditions).
• Hydrophobic Coating: Repels rain, mud, and sweat—maintains clarity in stormy rides.

🌓 All-Terrain Versatility

• Trail Running: Amber tint boosts contrast on rocky paths, reducing tripping risks by 30% in low light.
• Hiking/Mountaineering: Cat.3 darkness (8% light transmission) for alpine glare; transitions to Cat.1 (43%) in shaded forests.

♻️ Sustainable Performance

• Eco-TR90 Frames: 45% recycled ocean plastic (vs. virgin material in Smith Optics) .
• Impact Resistance: Lenses survive 30km/h gravel impacts (ASTM F803 sports safety certified) .
  
  

Urban Cycling:
