Nylon Polarized Lens Gradient Color Green Tinted
Engineered Optical Excellence
Every lens inherits five core performance pillars — from optical purity to impact safety.
Supreme Optical Clarity
Engineered exclusively as 0.00D Plano Lenses with an Abbe Value of 52, rivaling crown glass for ultimate optical purity. Thoroughly eliminates the "rainbow effect" and edge color dispersion typically associated with high-base polarized lenses.
Molecular-Level Polarization
Integrates premium Japan-imported PVA polarized film with the nylon base at a molecular level, ensuring absolutely no delamination even under intense CNC rimless drilling. Delivers a polarization efficiency of ≥99% to cut off severe glare.
Seamless Dual-Zone VLT
High-Temp Precision Dip-Dyeing achieves a flawless transition from Top CAT 3 (8-18% VLT) to Bottom CAT 2 (18-43% VLT). Strictly controlled batch symmetry with Delta E < 1.0 and zero visible color banding.
Precision Alignment Marks
To solve the industry pain point of tilted gradient lines during CNC edging, all gradient blanks feature high-precision, washable eco-ink horizontal axis lines. This completely eliminates alignment defects and maximizes your rimless assembly yield rate.
UV400 & FDA Impact Safety
Offers uncompromised 100% blockage of UVA and UVB rays (≤400nm, ≥99% blocking) consistently across both zones. The ultra-thin 1.5mm profile easily passes the FDA 21 CFR 801.410 drop-ball test.

Features & Applications
Technical Features
- Optical Purity: An Abbe Value of 52 closely matches crown glass. This high optical purity prevents the visual distortion that typically drives customer complaints, keeping your premium eyewear collections highly regarded.
- Advanced Polarization: Premium PVA polarized film is integrated at a molecular level. This robust construction completely prevents delamination during complex rimless frame assembly, while the ≥99% polarization efficiency secures a distinct competitive advantage for your sunglass lines.
- Precision Tint Control: High-Temp Precision Dip-Dyeing achieves a flawless gradient transition from CAT 3 to CAT 2. Strict Delta E < 1.0 batch symmetry completely eliminates rejected shipments caused by visible color banding.
- Regulatory Compliance: Uncompromised UV400 protection fully shields your business from liability risks. Furthermore, a guaranteed pass on the FDA 21 CFR 801.410 drop-ball impact safety test completely removes regulatory roadblocks for global export operations.
- Assembly Efficiency: Edge-chipping during CNC drilling is virtually eliminated due to the highly stable 1.01 g/cm³ specific gravity. Washable eco-ink horizontal axis marks on all gradient blanks solve alignment defects and maximize the rimless assembly yield rate.
- B2B Customization: Independent Eyewear Designers can prototype new lines with minimal financial risk. Custom diameters, tailored base curves, and precise Pantone color matching are available starting at a low 300-pair MOQ.

Dual-Zone VLT Reference
| Gradient Zone | VLT (%) | Category | Usage Environment |
|---|---|---|---|
| Top (Dark Zone) | 8% - 18% | CAT 3 | Direct sunlight, outdoor glare blocking |
| Bottom (Light Zone) | 18% - 43% | CAT 2 | Near-field clarity, reading, driving view |
Note: The gradient transition is continuous with zero visible banding. Delta E < 1.0 batch-to-batch consistency is enforced at the factory level.
Overview
A flagship polarized line requires a visual profile that balances sophisticated aesthetics with essential glare control. The gradient construction provides a continuous transition for near-field viewing, while the advanced polarization cuts blinding surface reflections during outdoor wear.
Precision tint control yields consistent color transitions, preventing the QA failures that often derail mass assembly. Paired with tailored customization for specific shade matching, your original design carries cleanly from concept to finished product. Xinxin builds the complete lens in-house, ensuring every prototype perfectly mirrors the final bulk run.
