PC Polarized Lens Gradient Color Gray Tinted
Engineered Optical Excellence
Every lens inherits five core performance pillars — from optical purity to impact safety.
Neutral Gray Gradient Tint
The top-to-bottom gray fade is built to the customer's zone targets across CAT 0–4 (final zone VLT/CAT confirmed at sampling), holding colors true while balancing overhead glare against lower-field clarity.
Commuter Glare Control
A premium polarizing film with ≥99% efficiency tames reflections from asphalt, car hoods, and glass facades.
Light Polycarbonate Gradient
Optical-grade 0.00D plano PC (Abbe 30, 1.20 g/cm³) offers an impact-ready, low-weight base that supports FDA drop-ball testing in production.
Gray Zones Held to Target
Spectrophotometer checks keep the gray fade and left/right symmetry on the customer-agreed Delta E target (reference: < 1.0) for every batch.
UV400 in Both Zones
UVA and UVB up to 400 nm are blocked at ≥99%, from the darker top to the lighter bottom.

Production-Ready Integration
Everything you need to source with confidence
- PC Full-Rim Frames — Recommended first choice. Have frame dimensions, the lens bevel profile, and glazing pressure checked against a sample to keep assembly from running overly tight.
- Other Full-Rim Frames in Scope — Also compatible with TR90 / Grilamid TR90 plus metal, titanium, stainless, and carbon fiber constructions; sample-verified glazing settings may be applied while eyewire closure tension stays controlled.
- Assembly Restrictions — Full-rim glazing only. Acetate frames are incompatible; any rimless drill-mount assembly is strictly prohibited.
- Pantone-guided development for the gray base tones and gradient transition approval, with repeat-order color matching
- Custom gradient zone ratio and zone transmission targets across CAT 0–4 (final zone VLT/CAT confirmed at sampling)
- Custom base curves, diameters, and B-AR (back-surface AR) coating for reduced rear-surface reflections in driving and outdoor use
- Coating upgrades: Hard Coat / Oleophobic / Hydrophobic / Anti-static
- Simple, premium, blister, or branded-logo packaging and labeling options
- MOQ: 300 pairs per style per color
- Sample Lead Time: 7–10 working days (reference; negotiable, quoted per confirmed specification)
- Bulk Lead Time: 15–20 working days (subject to quantity)
- Custom Base Curve / Color: 300 Pairs minimum
- Deep Custom: 500 Pairs minimum
- Custom Options: OEM/ODM, Pantone tone matching, gradient zone ratios, laser logo, B-AR and functional coatings
- Reports: Light Transmittance, UV Blocking, Impact Resistance, Color Consistency, Salt Spray, and Polarization Efficiency reports
Features & Applications
Technical Features
- Batch-Stable Gray Neutrality: Gray dye runs are watched for blue-cast drift, and spectrophotometer checks hold every batch to the customer-agreed Delta E target (reference: < 1.0), so replenishment orders match the signed sample rather than drifting toward a cooler shade.
- Consistent Gradient Placement: The dark-to-light transition line is set on the approved gradient master and held through production, giving frame programs predictable zone geometry instead of batch-to-batch fade variation.
- True-Color Glare Control: With a neutral gray spectral balance and a ≥99% efficiency polarizing film, the lens cuts reflections off asphalt, water, and glass while streetscapes and dashboards keep their natural color relationships.
- Feather-Light Impact Platform: The 0.00D plano optical-grade PC substrate (Abbe 30, 1.20 g/cm³) is specified to support FDA 21 CFR 801.410 drop-ball testing and keeps production frames light on the face.
- Export-Ready UV400 Package: Built-in absorbers block ≥99% of UVA and UVB through 400 nm, backed by CE / FDA / GB / ANSI / EN / AS/NZS documentation coverage for cross-border programs.
- Programmed Around Your Frame Brief: Optical Retailers and Sports & Automotive Lifestyle Labels can configure 2C–8C base curves, 71–80mm diameters, zone ratios, logo treatments, and B-AR or functional coatings from a 300-pair MOQ.

Overview
Drivers meet the sun at two heights — high at the wheel, low off the dash — and a gray gradient answers both without shifting any color. This is the neutral workhorse of a polarized line: quiet tint, true-color view, dual-zone comfort from morning drive to evening glare.
The fade is set once on the approved sample and held through every production run — the shade your team signs off is the shade that ships on reorder. Zone ratios, Pantone targets, and coating stacks are specified up front — Xinxin builds the whole program in-house, from brief to bulk.
Lens Category
| Gradient Zone | VLT (%) | Category | Usage Environment |
|---|---|---|---|
| Upper zone (reference layout) | 8% - 18% | CAT 3 | Direct overhead sun, sky and road glare |
| Lower zone (reference layout) | 43% - 80% | CAT 1 | Dashboard, near-field view, eye contact |
Note: Zone targets are developed to the customer’s specification across CAT 0–4; the final zone VLT/CAT and transition placement are confirmed at sampling.
