UV400 ultra strong protection monochrome TAC polarized sun lens

UV400 ultra strong protection monochrome TAC polarized sun lens is designed for harsh outdoor environments. It integrates cutting-edge technologies in optical engineering and materials science to provide all-round UV protection and visual optimization. It adopts a multi-layer composite structure of cellulose triacetate, combined with polarized light filtering technology and impact-resistant strengthening technology. While effectively blocking UV rays, the lens achieves a balance between glare elimination and color fidelity through precise optical adjustment. It is suitable for driving, water sports, high-altitude adventures and other scenes, providing professional-grade visual protection for all-weather outdoor activities.

Core features

1. Full-band protection system
The lens strictly follows international standards and forms a UV cutoff barrier at a specific wavelength through a special coating process. The measured UV blocking rate is extremely high. Its protection range covers UVA, UVB and UVC, which can effectively prevent eye damage such as cataracts and macular degeneration caused by long-term UV exposure.

2. Multi-layer composite polarization technology
The lens adopts a multi-layer composite structure: the core polarization layer is formed into a linear filter film through molecular directional stretching technology, which can filter horizontal polarization glare; the two middle layers of ultraviolet absorption layers use nano-scale metal oxide particles to achieve wide-spectrum ultraviolet absorption; the outer layer is covered with a high-hardness anti-scratch coating and an anti-reflection coating, and the surface friction coefficient is extremely low, effectively resisting wind, sand, and oil erosion. This structure can significantly reduce the intensity of road reflection under strong light and improve the clarity of water surface ripples.

3. Monochromatic optical system optimization
The neutral gray or brown monochromatic filter design is adopted. While maintaining appropriate visible light transmittance, the spectral response curve is adjusted to achieve low color deviation rate, ensuring a balance between natural color reproduction and contrast enhancement. This feature is particularly suitable for driving scenes - in a sudden change of light and dark environment, the lens can maintain visual clarity, while the anti-reflection coating significantly reduces the interference of windshield reflection.

4. Super-reinforced safety structure
The lens has passed strict impact resistance testing and has high impact resistance, which is equivalent to withstanding the impact of a tennis ball at a certain distance. Its impact-proof layer is made of polymer elastomer material, which maintains tensile strength in a wide temperature range and is suitable for high-dynamic sports scenes such as skiing and cycling. At the same time, the ultra-thin design and ergonomic curvature achieve the unity of lightweight and wearing comfort.

5. Multi-scenario adaptability design
The lens has passed multiple international certifications and meets universal standards. Its polarization angle has been professionally adjusted to eliminate water surface reflections when fishing and improve the recognition of fish floats; in snowy environments, it reduces the risk of snow blindness through glare suppression. In addition, the hydrophobic coating on the surface of the lens can make the contact angle of water stains larger, keeping the field of vision clear when driving in rainy days.

6. Industrial-grade durability guarantee
Using vacuum ion plating technology, the lens has low transmittance attenuation and high polarization efficiency after long-term exposure in ultraviolet accelerated aging tests. Its scratch-resistant coating can pass friction tests and resist scratches from hard objects such as keys and coins in daily use. With customizable curvature design, the lens can be adapted to a variety of carriers such as sports frames and optical frames to meet personalized needs.
