Nylon Polarized Lens Solid Color Gray 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, this gray polarized lens features an Abbe Value of 52, rivaling crown glass for ultimate optical purity. Thoroughly eliminates the "rainbow effect" and edge color dispersion typically associated with high-base polarized lenses.
Molecular-Level Polarization
this gray polarized lens integrates premium Japan-imported PVA polarized film with the nylon base at a molecular level. Delivers a polarization efficiency of ≥99%, completely cutting off glaring reflections from water and snow while enhancing visual contrast.
Zero Internal Stress Design
Manufactured with an advanced low-stress injection process. This molecular synergy ensures zero edge chipping and absolutely no delamination of the polarizing film on this gray tinted lens, even under the intense tension of CNC drilling for rimless assemblies.
Strict Color Consistency
Utilizing Precision Dip-Dyeing and automated spectrophotometer monitoring, we ensure strict batch-to-batch solid base color consistency for these gray lenses with a strictly controlled Delta E < 1.0.
UV400 Full Protection
this gray polarized lens offers uncompromised safety through strictly controlled material properties, delivering 100% blockage of harmful UVA and UVB rays (≤400nm, ≥99% blocking) while easily passing the FDA 21 CFR 801.410 drop-ball test.

Overview
A flagship sunglasses line requires a dark neutral polarized lens that preserves natural color recognition under intense sunlight. This solid gray profile provides true-color perception and glare reduction, making it a reliable cornerstone for premium collections.
Tighter color matching and stable dye saturation prevent off-shade shipments that drift toward blue or purple and disrupt delivery schedules. Pantone-matched Couture Gray tints can be specified in your design brief — Xinxin manages the full customization flow in-house to deliver exact prototypes.
