Nylon Sunglasses Lens Dual Gradient Blue 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-Color Transition
Advanced Double High-Temp Precision Dip-Dyeing achieves a flawless, harmonious transition from the top color to a contrasting bottom color. Strictly controlled batch symmetry with Delta E < 1.0 ensures zero muddy color mixing or visible banding at the intersection zone.
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 top and bottom color 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 closely rivals the clarity of crown glass. This high-grade nylon prevents visual distortion, drastically lowering defect-related return rates for luxury fashion labels.
- Cool-Tone Dual Gradient: Double high-temp dip-dyeing achieves a flawless fade from a deep blue top to a lighter bottom, delivering a premium fashion-forward aesthetic. Meticulous control eliminates cool-tone drift (such as unwanted cyan or purple shifts), keeping your production timelines intact.
- UV400 Compliance: Total blockage of both UVA and UVB rays (≤400nm) is consistently guaranteed across the entire blue transition zone. Strict adherence to international sun protection standards easily removes regulatory friction for global optical retailers.
- Mechanical Safety: Passed the FDA 21 CFR 801.410 drop-ball test with distinction. Outstanding impact resistance drastically minimizes warranty claims and protects your brand’s reputation for premium quality.
- Ultra-Lightweight Comfort: A specific gravity of 1.01 g/cm³ significantly reduces the overall weight of the finished eyewear. High mechanical stability also secures rimless frame assembly by virtually eliminating material chipping during CNC slotting.
- Dimension Flexibility: Confidently prototype diverse frame shapes with minimal inventory risk. Available in versatile diameters up to 80mm and customized base curves (2C-8C) starting at a highly accessible 300-pair MOQ.
Perfect For
- Premium Eyewear Brands
- Independent Eyewear Designers

- Concept & Multi-Brand Stores
- E-commerce D2C Brands
Dual-Color Gradient Reference
| Gradient Zone | Example VLT (%) | Category | Description |
|---|---|---|---|
| Top Color Zone | 8% - 18% | CAT 3 | Deep tint for direct sunlight and glare blocking |
| Bottom Color Zone | 18% - 43% | CAT 2 / CAT 1 | Contrasting tint for near-field clarity and aesthetic transition |
Note: The bi-color gradient transition is continuous with zero muddy color mixing. Delta E < 1.0 batch-to-batch consistency is enforced at the factory level.
Overview
Tinted gradient lenses must deliver a flawless color fade to support high-end eyewear designs without compromising on visual clarity. A precise dual-tone blue fade provides the aesthetic depth required for bold, fashion-forward frame collections.
High-grade dip-dyeing maintains a stable cool hue across every shipment, so your retail line avoids the QA stops caused by cyan or purple color drift. Customizing the tint profile and coating stack happens entirely in-house at Xinxin, turning your design intent into a finalized sample within a standard production cycle.
