The global cosmetic and medical contact lens landscape is undergoing a massive paradigm shift. No longer are buyers forced to choose between vibrant pigment styling and physiological comfort. Modern Hypercolor Contact Lenses leverage advanced HEMA-NVP and silicone hydrogel matrix structures combined with embedded sandwich printing technology to deliver striking cosmetic finishes while ensuring maximum oxygen transmissibility (Dk/t) and biocompatibility.
As a leading national high-tech enterprise, Guangzhou Dewy Lenses Co., Ltd. (established in 1996) has remained at the vanguard of this engineering revolution. By integrating automated CNC precision lathe-cutting, cast molding, and semi-molding processes, we deliver massive-scale OEM/ODM manufacturing capability that meets the stringent requirements of global optical brands, distributors, and pharmaceutical importers.
Explore our primary B2B product portfolio designed for high visual impact, safety, and ultimate wearability.
Established in 1996, Guangzhou Dewy Lenses Co., Ltd. is a leading high-tech enterprise integrating product design, research, and large-scale production of premium soft contact lenses and care products. As a high-tech national enterprise, we integrate product design, research, and large-scale production of soft hydrophilic contact lenses and care products. Our commitment to excellence ensures every lens meets the highest standards of comfort, clarity, and safety.
Equipped with fully automatic CNC production lines, we utilize an advanced semi-molding process that organically unifies lens appearance and formability. We cater to diverse market needs, offering premium yearly, half-yearly, and daily disposable lenses. Our custom dye formulation ensures that complex designs like hypercolor and three-tone lenses are entirely embedded inside the lens core, ensuring zero physical contact with the cornea.
Every single lens is subjected to a comprehensive, fully automated inspection and sterilization protocol.
Why global brands trust Chinese contact lens manufacturers for large-scale operations.
Guangzhou sits at the heart of the world's most robust electronics and medical injection-molding industrial ecosystem. Our proximity to high-purity monomer suppliers and logistics corridors minimizes transport costs and guarantees predictable lead times.
Our CNC tooling process allows for incredibly fine design tolerances of down to ±0.01 mm. This level of accuracy is essential for creating multi-focal designs, high-definition cosmetic pupil layers, and specialized prosthetic visual wear.
With multiple high-speed production lines operating in 100,000-grade sterile conditions, we can easily ramp up capacity to produce millions of lenses monthly. This level of scale prevents out-of-stock events for our global B2B clients.
Meeting medical device standards for frictionless import across Americas, EU, and APAC markets.
Exporting medical-grade contact lenses requires rigorous adherence to local health authorities. Guangzhou Dewy Lenses maintains certifications such as CE0123 / CE1639, ensuring compatibility with European Union directives.
Our manufacturing processes conform to ISO 13485 (Medical Devices Quality Management Systems), providing transparency during customs clearance and local regulatory audits.
Every market has unique consumer requirements regarding package labelling, language, and design. We offer fully custom OEM boxes, localized booklets, and distinct multi-language warning labels to comply with target market laws.
From single daily-disposable blisters to yearly glass vials and specialized travel kits, our packaging processes are adaptable and designed to preserve absolute sterility.
| Parameter / Standard | Technical Specification | Clinical / Market Context |
|---|---|---|
| Base Curve (BC) | 8.4 mm - 8.6 mm | Optimized for global anatomical averages to prevent lens slippage. |
| Diameter (DIA) | 14.0 mm - 14.5 mm | Provides natural sizing to enlarging visual effects (ideal for cosmetics). |
| Water Content | 38% - 42% (Yearly) / 55% (Daily) | High water content for daily disposables, low-dehydration rate for yearly lenses. |
| Material Matrix | HEMA + NVP Hydrogel & Silicone Hydrogel | Ensures high oxygen permeability (Dk) and protein deposition resistance. |
| Pigment Tech | Double-Sandwich Color Isolation | Pigment is locked inside the hydrogel polymer layer; 0% color fading or irritation. |
| Sterilization Method | Moist Heat Autoclaving (121°C for 20 mins) | Guarantees a Sterility Assurance Level (SAL) of 10^-6. |
Aligning with user search intent by matching product variations with target consumer segments.
Influenced by pop culture, the demand for natural-looking yet vibrant cosmetic lenses is growing. Three-tone color lenses seamlessly blend with the user's natural iris color, making them highly popular in North America and Western Europe.
For patients with corneal scarring or heterochromia, customized brown and prosthetic lenses restore symmetry and psychological confidence. Our micro-lathe production ensures precise color mapping and prescription integration.
Modern consumers prefer ready-to-use bundles. Providing accessories like silicone travel removers, tweezers, and mirror storage boxes allows online optical retailers to boost average order value (AOV) and build brand loyalty.

Critical answers to questions frequently asked by optical importers, retail distributors, and procurement managers.
We utilize a proprietary "Double-Sandwich Technology." In this design, the raw pigments (such as titanium dioxide, iron oxides, and copper phthalocyanine) are completely encased within layers of clear hydrogel (HEMA/NVP). The colored layer never makes direct contact with the wearer's cornea or palpebral conjunctiva, eliminating chemical irritation and pigment wear-off.
Yes. We offer complete OEM customization for diopter values ranging from 0.00D to -10.00D (and up to -15.00D on request) with step options of 0.25D or 0.50D. We can also adapt base curves (BC) and diameters (DIA) to meet specific local market distributions.
For custom outer packaging (paper boxes, sterile blister foils, or specialized kits), our standard MOQ is 1,000 to 3,000 units per layout design. We offer pre-designed template packaging options for smaller test-market launches.
All lenses are sealed inside medical-grade aluminum-plastic blisters containing buffered saline solution. They undergo wet-heat sterilization in industrial autoclaves at 121°C under pressure for a minimum of 20 minutes. This achieves a validated Sterility Assurance Level (SAL) of 10^-6, ensuring a safe shelf-life of up to 5 years.
Yes, our factory has maintained ISO 13485 certification for medical devices since our early years. Our cosmetic and prescription series hold CE0123 / CE1639 registrations, permitting direct sales in all countries recognizing the European Medical Devices Regulation (MDR) and related frameworks.
For standard inventory items, order preparation takes 7 to 15 days. For large-scale customized OEM/ODM projects (incorporating private label designs and customized base curves), lead times vary between 30 to 45 days, depending on raw material sourcing and production schedule slots.
