Nylon Sunglasses Lens Gradient Pink 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. Low internal stress design guarantees minimal optical distortion and zero edge color fringing.
Seamless Dual-Zone VLT
High-Temp Precision Dip-Dyeing achieves a flawless transition from Top CAT 2 (18-43% VLT) for glare blocking to Bottom CAT 1 (43-80% VLT) for near-field clarity. Strictly controlled batch symmetry with Delta E < 1.0 and zero visible color banding.
Ultra-Lightweight & Crack Resistant
Specific Gravity of 1.01 for a truly weightless wearing experience. Delivers exceptional mechanical stability, absolutely immune to edge chipping during CNC drilling and slotting for rimless designs.
UV400 Full Protection
Offers uncompromised 100% blockage of UVA and UVB rays (≤400nm, ≥99% blocking) consistently across both the dark and light transition zones.
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.

Features & Applications
Technical Features
- Optical Purity: An Abbe Value of 52 rivals crown glass for clarity. This high-grade nylon (PA-12) eliminates the visual distortion that typically drives customer complaints and damages brand reputation.
- Seamless Dual-Zone VLT: High-temp precision dip-dyeing achieves a flawless transition from Top CAT 2 (18-43%) to Bottom CAT 1 (43-80%). Strict Delta E < 1.0 batch symmetry completely eliminates rejected shipments due to visible color banding.
- Assembly Efficiency: Washable eco-ink horizontal axis lines provide precision alignment marks for CNC edging. This solves the industry pain point of tilted gradient lines and maximizes the rimless assembly yield rate for Independent Eyewear Designers.
- Scrap Reduction: Edge-chipping during CNC drilling and slotting is virtually non-existent. The ultra-low specific gravity of 1.01 g/cm³ delivers the mechanical stability needed to lower material waste during assembly.
- Regulatory Compliance: We guarantee 100% blockage of UVA and UVB rays (≤400nm) consistently across both transition zones. This full UV400 and FDA 21 CFR 801.410 compliance keeps Premium Eyewear Brands safe from regulatory roadblocks and liability risks.
- Scalable Manufacturing: Test specialized gradient designs with minimal financial risk. Pantone color matching and custom VLT zone ratios are available starting at a low 300-pair MOQ.
Perfect For
- Premium Eyewear Brands
- Independent Eyewear Designers
- Private Label Distributors
- Concept & Multi-Brand Stores
- E-commerce D2C Brands
- Optical Retailers
Dual-Zone VLT Reference
| Gradient Zone | VLT (%) | Category | Usage Environment |
|---|---|---|---|
| Top (Dark Zone) | 18% - 43% | CAT 2 | Direct sunlight, outdoor glare blocking |
| Bottom (Light Zone) | 43% - 80% | CAT 1 | 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
Fashion-forward gradient tinting requires a delicate balance between outdoor glare defense and near-field reading comfort without sacrificing the aesthetic vision of the collection.
Consistent dip-dyeing chemistry holds the color transition steady across every batch, so your design intent reaches the retail floor without alignment errors or shade variance. Custom Pantone-matched fades and tailored coating stacks are built entirely in-house at Xinxin, keeping your design-to-sample cycle tight and predictable.
