Established in 1996, Guangzhou Dewy Lenses Co., Ltd. has stood at the forefront of the optical industry for over two decades. As a high-tech national enterprise, we specialize in the comprehensive integration of 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. By utilizing advanced semi-molding processes and fully automatic CNC production lines, we unify lens appearance with structural formability, creating products that are as healthy as they are beautiful.

In the era of rapid fashion and medical-grade demands, our "Smart Factory" model provides unmatched advantages for global partners.
Our factory employs modular production lines that can quickly pivot between bi-color, tri-color, and natural aesthetic designs. This flexibility allows us to handle both massive wholesale orders and specialized "Small Batch" custom runs without compromising lead times.
Leveraging China's robust industrial ecosystem, we source high-purity HEMA and silicone hydrogel materials through verified sustainable channels, ensuring consistent oxygen permeability and water content across all batches.
Integration of computer vision in our OQC (Outgoing Quality Control) phase ensures that 100% of lenses are scanned for microscopic defects, edge smoothness, and pigment centering, reducing return rates to near-zero.
Where Medical Science Meets Aesthetic Perfection
The core of our Bi-color lens dominance lies in "Sandwich Technology." Unlike cheaper alternatives, our pigments are encapsulated between two layers of clear lens material. This prevents any direct contact between the colorant and the cornea, ensuring zero pigment migration and maximum eye health.
The future of Bi-color lenses is high-breathability. We are currently scaling our production of third-generation Silicone Hydrogel lenses, which offer up to 5x more oxygen transmissibility than traditional HEMA lenses, allowing for extended wear without redness or fatigue.
Our R&D team is working on 3D Iris Scanning to create "Natural-Fit" bi-color patterns that mimic the unique textures of the human eye, providing a level of realism previously only available in custom prosthetic lenses.

As a leading China Bi-Color Contact Lenses factory, we provide more than just optics; we provide a gateway to market leadership for our clients.
1. Verification: Ensure the factory holds a valid Medical Device Manufacturing License.
2. Technology: Confirm use of "Sandwich" color printing for safety.
3. Samples: Always request OQC reports for sample batches.
4. Logistics: Verify cold-chain or temperature-stable shipping for long-distance transport.
Bi-color lenses utilize a two-tone gradient, typically combining a darker outer limbal ring with a lighter inner shade. This adds depth and dimension to the iris, creating a more natural yet striking transformation compared to flat single-color lenses.
Yes, we are a high-tech national enterprise with full certifications for medical device production. Our facility uses fully automatic CNC lines to maintain medical-grade precision.
Our lenses are available in daily, monthly, half-yearly, and yearly disposable formats. In sealed blister packaging, they typically have a shelf life of 3-5 years from the date of sterilization.
Absolutely. We provide end-to-end packaging solutions, from ivory board carton boxes to custom-designed lens cases and tweezers kits, allowing you to launch a complete brand ecosystem.
We use medical-grade, non-toxic pigments and lock them within the lens matrix using semi-molding technology. This ensures the eye is never in contact with the color layer.
