Nylon Sunglasses Lens Gradient Color Brown 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 Purity: An Abbe Value of 52 closely matches crown glass for exceptional visual clarity. This premium nylon construction completely eliminates the optical distortion that typically drives customer complaints and damages brand reputation.
- Dual-Zone VLT Control: The seamless transition from CAT 3 (8-18%) sun protection to CAT 2 (18-43%) near-field clarity adds significant functional value to your designs. Our high-temp dip-dyeing process enforces strict Delta E < 1.0 color consistency, preventing costly assembly rejections.
- UV400 Compliance: We guarantee 100% blockage of UVA and UVB rays (≤400nm) across both the dark and light transition zones. This full compliance keeps your business safe from regulatory roadblocks and global export liabilities.
- Scrap Reduction: Maximize your rimless assembly yield rate by virtually eliminating edge-chipping during CNC drilling. The ultra-low specific gravity of 1.01 g/cm³ delivers a truly weightless wearing experience while maintaining supreme mechanical stability.
- Mechanical Safety: Protect your brand equity and minimize post-sale warranty claims with reliable shatter resistance. These gradient lenses strictly pass the FDA 21 CFR 801.410 drop-ball test alongside comprehensive CE, ANSI, and UKCA certifications.
- Scalable Manufacturing: Test custom gradient zone ratios, Pantone color matching, and bespoke base curves (2C-8C) efficiently. This flexible OEM production is highly accessible at a 300-pair MOQ, making it ideal for Luxury Fashion Houses and Premium Eyewear Brands launching distinct collections.
Perfect For
- Premium Eyewear Brands
- Independent Eyewear Designers
- Private Label Distributors
- Luxury Fashion Houses
- Concept & Multi-Brand Stores
- E-commerce D2C Brands
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
Continuous visual transitions define the true quality of a gradient profile. A premium tinted gradient requires precise control over color depth and optical purity to meet the strict aesthetic demands of high-end collections.
Precise dip-dyeing maintains strict batch-to-batch color consistency, ensuring your production runs smoothly without rejected shipments. For custom programs, our in-house engineering team translates your specific color brief and coating requirements into a sample-ready prototype before full manufacturing begins.
