Nylon Polarized Lens Gradient Color Purple 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 exceptional Abbe Value of 52 closely matches crown glass, offering the precise visual clarity your high-end customers demand. This premium nylon material prevents color dispersion and optical distortion at the lens edges.
- High-Efficiency Polarization: Integrated Japan-imported PVA film delivers a polarization efficiency of ≥99% to completely cut off blinding surface glare. This robust performance upgrade provides a critical selling point for outdoor and driving collections.
- Dual-Zone Light Attenuation: A flawless fade from a CAT 3 top to a CAT 2 bottom provides reliable overhead sun protection while maintaining near-field visibility. Strict Delta E < 1.0 batch symmetry completely eliminates rejected shipments caused by inconsistent purple gradients.
- Complete Eye Defense: Full UV400 compliance blocks 100% of harmful UVA and UVB radiation. Guaranteeing these safety certifications shields your brand from regulatory delays during global export operations.
- Assembly Efficiency: The ultra-lightweight 1.01 g/cm³ specific gravity provides high mechanical strength to prevent edge-chipping during CNC drilling. This durability significantly reduces material waste and lowers your overall production costs.
- Mechanical Safety & Scalability: Robust FDA 21 CFR 801.410 drop-ball compliance minimizes warranty claims for Premium Eyewear Brands. Custom diameters, bespoke base curves, and precise Pantone color matching are easily accessible starting at a flexible 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
Outdoor and driving collections demand a tinted lens that pairs continuous top-to-bottom shading with reliable glare reduction. High-end fashion programs require smooth color transitions that never compromise on visual clarity.
