Nylon Sunglasses Lens Dual Gradient 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. 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.

Production-Ready Integration
Everything you need to source with confidence
- Acetate Frames — Highly recommended. Excellent chemical resistance against acetate plasticizers. Completely immune to stress cracking caused by Acetate's cooling shrinkage during fitting.
- Rimless / Drill-mount — Supreme tensile strength ensures zero edge chipping during CNC drilling and slotting.
- Titanium / Carbon Fiber / Metal / TR90 Frames — Optimal compatibility, lightweight and corrosion-resistant, ideal for premium eyewear frame designs.
- Independent Pantone matching for both top and bottom gradient base colors (e.g., deep green to light green, or green to green dual gradient)
- Custom transition ratios and overlap control (e.g., 50/50 split, or 60% top color dominance)
- B-AR (Back-Surface AR) coating recommended to eliminate rear reflections
- Coating upgrades: HC / Oleophobic / Hydrophobic / Anti-static
- Custom packaging and labeling, including PE bag, plain box, individual color box, cloth bag, or brand LOGO packaging
- MOQ: 300 Pairs/Specification
- Sample Lead Time: 7–10 working days, allowing you to verify gradient quality before bulk order
- Bulk Lead Time: 15–20 working days (subject to quantity and customization complexity)
- Custom Options: OEM/ODM, 2-Tone Pantone matching, custom transition ratios, B-AR coating, laser logo, custom packaging
- Reports: Light Transmittance Test Report, UV Blocking Test Report, Impact Resistance Test Report, Color Consistency (Delta E) Test Report, Salt Spray Test Report
Features & Applications
Technical Features
- Optical Purity: An Abbe Value of 52 rivals crown glass for clarity. This premium nylon (PA-12) material eliminates the visual distortion that often drives customer returns for high-end optical brands.
- Precision Dual-Zone Tinting: Advanced double dip-dyeing ensures a flawless transition from a CAT 3 dark top to a CAT 2 lighter bottom. Strict Delta E < 1.0 color consistency entirely prevents assembly rejections due to muddy color mixing.
- Complete UV Defense: We guarantee uncompromised 100% blockage of UVA and UVB rays (≤400nm) across both gradient zones. This full compliance completely shields your distribution network from regulatory liability risks.
- Mechanical Durability: Post-sale warranty claims drop significantly due to reliable shatter resistance. Passing the FDA 21 CFR 801.410 drop-ball test, these lenses also virtually eliminate edge-chipping waste during rimless CNC assembly.
- Design Flexibility: Independent Eyewear Designers can easily bring unique frame concepts to life. Broad base curve availability (2C to 8C) ensures a perfect physical match across acetate, rimless, and titanium frame architectures.
- Manufacturing Scalability: Test specialized green gradient collections efficiently with minimal financial exposure. Scalable production featuring custom diameters up to 80mm and independent Pantone matching is highly accessible at a low 300-pair MOQ.

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.
