Evidence-backed Industrial Belt Guide

Where Eyewear Is Made in China

Danyang in Jiangsu and Ouhai District in Wenzhou are complementary verified eyewear sourcing regions. Danyang has strong evidence for lenses, frames, components and a broader visual-industry ecosystem. Ouhai has current evidence for frame and finished-eyewear production, quality services and export-oriented OEM or ODM activity. Buyers must match each supplier to lenses, frames, coatings or final assembly and verify the exact product and destination-market requirements. [1][2][3][4]

Manufacturing cluster vs wholesale market

Manufacturing cluster

Danyang supports lenses and broader eyewear manufacturing; Ouhai supports frames and finished-eyewear manufacturing.

Wholesale or trading market

Showrooms, eyewear-city merchants and export services support trade but do not prove production ownership.

Regional sourcing model

Complementary manufacturing regions requiring supplier-level process and regulatory checks.

Best for / less suitable for

Best for

  • Lens and optical-component research
  • Frame and complete-eyewear OEM or ODM
  • Retail and private-label eyewear programs
  • Buyers able to verify optical and material specifications

Less suitable for

  • Buyers treating frames, lenses and complete eyewear as identical capabilities
  • Safety or medical claims without regulatory review
  • UV400 or CE wording accepted without product-matched evidence
  • Orders without model-specific testing

How to verify that a supplier is connected to this cluster

  1. Define frame material and process, including acetate, metal, TR90 or injection requirements.
  2. Confirm lens material, optical power, optical-center accuracy, prism and coating.
  3. Test UV protection, polarization, light transmission and impact resistance where relevant.
  4. Check hinge cycles, screws, plating, corrosion, dimensional fit and nickel release.
  5. Identify destination-market standards and distinguish optical frames, plano sunglasses, safety eyewear and regulated optical products.
  6. Verify that each test report covers the exact model, material, lens, coating and color.
  7. Approve packaging, cases, labeling and a representative production sample.

Buyer risks and caveats

  • UV400 printing does not prove UV performance.
  • CE marking alone does not verify every eyewear requirement.
  • Lens, frame, coating and final assembly may be performed by different companies.
  • Regional evidence cannot validate a supplier's reports or regulated product claims.
