District Vision Ashima Horizon Blade Alpine Moss D+ Copper Mirror

District Vision Ashima Horizon Blade Alpine Moss

The Ashima Horizon Blade was developed in collaboration with Ashima Shiraishi over two years of iterative testing, focusing on lens geometries optimized for outdoor climbing. Utilizing a 6-base frame construction, the frame incorporates extended peripheral lens coverage for enhanced visual protection. The lens design features four strategically placed ventilation holes near its center, engineered to improve airflow and reduce fogging under dynamic conditions. The 125mm temples are specifically constructed to accommodate helmet use, making the frame suitable for climbing and cycling applications. The D+ Copper Mirror lens mitigates reflected light and allows 10.03% of visible light transmission, 6.06% of blue light transmission, and blocks 100% of UVA/UVB rays, making it an optimal lens for prolonged outdoor use.
