Nylon Sunglasses Lens 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-Zone VLT
High-Temp Precision Dip-Dyeing achieves a flawless transition from Top CAT 3 (8-18% VLT) for glare blocking to Bottom CAT 2 (18-43% 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 Clarity: An Abbe Value of 52 provides visual purity that closely rivals crown glass. This high-grade nylon foundation completely eliminates the optical distortion responsible for end-user returns.
- Tint Precision: High-temp dip-dyeing maintains a highly consistent Top CAT 3 to Bottom CAT 2 gradient fade. Strict batch color control (Delta E < 1.0) reliably prevents rejected shipments during final frame assembly.
- Comprehensive UV Protection: Uncompromised 100% blockage of UVA and UVB rays (≤400nm) remains constant across both the dark and light zones. This strict adherence to global safety standards insulates your business from regulatory liabilities.
- Assembly Efficiency: The ultra-low specific gravity of 1.01 g/cm³ delivers exceptional mechanical stability. This structural strength drastically cuts material scrap by preventing edge chipping during rimless CNC drilling.
- Impact Certification: Rigorous FDA 21 CFR 801.410 drop-ball testing guarantees robust shatter resistance. This verifiable mechanical durability directly minimizes post-sale warranty claims for premium eyewear collections.
- Flexible Scalability: Independent Eyewear Designers can easily prototype specialized frame interfaces using available 2C to 8C base curves. Custom Pantone matching and adjustable gradient zone ratios are highly accessible at a 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 gradient lens must carry a flawless visual fade to preserve the aesthetic intent of a flagship design. This optical-grade tinted component provides a reliable transition that filters direct glare while keeping lower-field vision clear.
Tighter color control and faster sample turnaround come from a fully integrated production chain, ensuring the shade your team signs off on is the lens your factory ships. Custom fade ratios and tailored coating stacks are the customization baseline—every spec carries from your brief to the finished sample without compromise, all built under one roof in Shenzhen.
