Project Overview

  • Target Market: United States & Global Expansion

  • Core Deliverables: Precision replacement lenses (Polarized/Non-polarized), Medical-grade silicone accessories, Custom sports prescription lenses, and Complete sunglasses solutions.

  • Collaboration Timeline: Since 2011 (15 Years of Strategic Partnership)

  • Manufacturing Partner: Karuson Eyewear Factory


I. Customer Background

Founded in 2010, Walleva Inc. (brand: walleva®) is a premier US-based sports eyewear brand. Operating through global third-party platforms and independent stores, Walleva has built a stellar reputation for excellence. Their rapid ascent to becoming a market leader was fueled by a vision for high-performance optics, supported by the robust manufacturing capabilities of a professional eyewear factory.


II. Core Collaboration Highlights

Phase 1: The Foundation—Reliable Quality from Day One

The partnership began in 2011 with a focus on specialized replacement lenses. As a nascent brand, Walleva needed an eyewear factory that could guarantee consistency even for small-scale, high-precision orders. By delivering reliable polarized clarity and rapid response times, Karuson established the foundational trust required for a decade-long journey.

Phase 2: Innovation & Scaling—Engineering "Excellence"

As Walleva grew, Karuson evolved from a supplier into a technical innovator. We introduced industry-leading technologies to their lineup, including

  • Advanced Coatings: High-performance Revo, Iridescent, and Full-frame goggle coatings.

  • Material Safety: Integrated food-grade silicone for all eyewear accessories, setting a new safety standard in the industry.

  • Massive Catalog Expansion: Grown from a few models to nearly 400 lens types, covering 17 major sports brands.

  • Premium Protection: Launched the Mr. Shield® polarized series, meeting ANSI Z87.1 standards with specialized oil and seawater resistance.

  • Engineering Breakthroughs: Developed a unique 230mm magnetic-screw helmet lens for the Giro Air Attack, a rare market find that garnered widespread consumer praise.

    Phase 3: Diversification—A Complete Ecosystem Solution

    To help Walleva dominate the sports niche, our eyewear factory expanded production beyond lenses. Karuson now provides a "Full-Service Matrix":

    1. Core Optics: Custom polarized and prescription lenses.

    2. Ancillary Parts: Precision screws, clip-ons, and frames.

    3. Apparel Sourcing: Leveraging our integrated supply chain for complementary sports gear. This "Core + Accessories + Services" model allowed Walleva to streamline their procurement and focus entirely on global branding.

    Phase 4: Technical Pioneering—The Rx Sports Breakthrough

    In 2016, Karuson broke new ground by becoming the first eyewear factory in the sector to develop sports-specific myopic polarized lenses. This innovation filled a massive market gap for prescription-wearing athletes, further cementing Walleva’s position as an industry pioneer.

  • Consumer Trust: Maintained top-tier ratings across all major e-commerce platforms for product durability and packaging.

  • Global Reach: Successfully expanded business operations from the US to every major international market.

The 15-year synergy between Karuson and Walleva serves as a definitive model of how a dedicated eyewear factory can empower a brand to achieve global market leadership.

Wholesale Foldable Kids Sunglasses – TR90 Flexible Frame, Custom Logo & Colors, OEM/ODM Available, Low MOQ

Sourcing kids' eyewear for your private label or retail line? This foldable kids sunglasses model is built on a flexible TR90 frame — a material buyers trust for low return rates, since it resists snapping under normal wear and holds up to shipping and handling far better than rigid acetate or PC frames.

The flat-fold hinge design reduces packaging volume for freight, and the gradient two-tone colorway is fully customizable: we can match Pantone codes, adjust the gradient ratio, or produce solid colors on request. Frame front, temple color, and lens tint can each be specified independently for private label differentiation.

Lenses are UV400 rated with test reports available on request, and frame material is compliant with standard children's product safety requirements (CE / REACH — confirm specific certification needs at inquiry). Logo customization is available via pad printing, laser engraving, or in-mold branding on the temple, with artwork proofs provided before production.
