In the modern ophthalmic market, UV protection in contact lenses is no longer a luxury feature but a critical health requirement. As a global OEM/ODM UV Protection Contact Lenses Supplier, Guangzhou Dewy Lenses Co., Ltd. recognizes the increasing consumer demand for ocular health preservation. Ultraviolet radiation (UVA and UVB) contributes significantly to the development of cataracts, macular degeneration, and photokeratitis.
Our white paper explores how we integrate advanced ultraviolet-absorbing monomers into the polymer matrix of soft hydrophilic lenses, ensuring that the protective barrier is permanent and does not compromise oxygen permeability or comfort.
Years of Manufacturing Expertise
Established in 1996, we have transitioned from a local manufacturer to a global high-tech leader, integrating product design, deep R&D, and mass-scale production of premium soft contact lenses.
Utilizing high-purity Benzophenone-based UV absorbers that are covalently bonded to the HEMA-based material. This ensures 90% UVA and 99% UVB blockage.
The roadmap includes the transition to Silicone Hydrogel materials, offering 5x more oxygen transmissibility while maintaining Class I UV blocking standards (ISO 18369).
Researching photochromic lenses that adjust tint based on light intensity, combined with blue-light filtering for digital-heavy lifestyles.
Our facility in Guangzhou represents the pinnacle of Contact Lens Factory 4.0. Equipped with fully automatic CNC production lines, we utilize an advanced semi-molding process that organically unifies lens appearance and formability. This ensures unmatched batch-to-batch consistency for our global OEM partners.
We provide full-spectrum branding services, from lens design to ivory board paper packaging. Our Custom Logo Colored Contact Lens Packaging solutions allow brands to enter the market with a professional, high-end identity.
Leveraging 27 years of data, we help partners develop daily, half-yearly, and yearly disposable lenses that meet specific regional physiological needs, such as high water content for dry climates.
Navigating the complex regulatory landscape of Class II/III medical devices. We provide full documentation for export to Europe, Southeast Asia, and the Americas.
For large-scale distributors and e-commerce aggregators, sourcing from an established Contact Lens Exporter involves more than just price. It requires a partner who understands:
A1: While sunglasses protect the entire eye area, UV-blocking contact lenses protect the cornea and internal ocular structures directly. For maximum protection, we recommend a "dual-layer" approach: UV lenses combined with wrap-around sunglasses.
A2: Unlike traditional lathe cutting, CNC semi-molding provides a smoother surface and more stable edge geometry. This results in higher comfort levels and consistent power distribution across the lens.
A3: Yes. As an OEM provider, we offer various material formulations, typically ranging from 38% (for durability/yearly) to 58% (for high comfort/daily) water content.
A4: We offer flexible MOQs for growing brands, with tiered pricing structures that reward high-volume long-term partnerships.
