Direct from our ISO-certified facilities. Fully customizable parameters, optimized water retention, and high oxygen permeability.
As an industrial-scale manufacturing leader, Guangzhou Chroma Lenses Technology Co., Ltd. is specialized in the research, development, and mass production of premium contact lenses and custom cosmetic color lenses. Based in Dongguan, China—the global center of high-tech manufacturing—our state-of-the-art facility integrates advanced polymer engineering, automation machinery, and robust supply chain models.
Through our specialized OEM/ODM services, we deliver high-quality custom options to distributors, vision brands, and healthcare retailers globally. We operate under stringent quality management systems to guarantee compliance with international health regulations.
In contact lens design, diameter plays a fundamental role in physiological comfort, stabilization, and corneal oxygenation. A 14.0mm diameter is widely regarded as the optimal dimensional target for cosmetic and corrective contact lenses. It corresponds precisely to the average horizontal visible iris diameter (HVID) of human corneas, which typically ranges from 11.5mm to 12.0mm.
By designing the lenses with a total diameter of 14.0mm and a base curve range of 8.5mm to 8.6mm, we achieve a balance that matches the physiological structure of the eye:
SEO Insight & Physiological Comfort: Lenses below 13.8mm can easily become decentered, causing visual distortion. Lenses exceeding 14.2mm (without proper oxygen permeability design) risk restricting tear exchange, leading to corneal hypoxia and dry eyes. Our 14.0mm series represents the ideal sweet spot for B2B distributors seeking consistent customer satisfaction.
Our factories produce lenses utilizing high-grade Hydrogel (Polyhema/Poly-HEMA) and advanced Silicone Hydrogel (SiHy) materials. Through precise polymerization and monomer cross-linking, we optimize water retention properties and mechanical strength:
| Material Spec | HEMA-MAA Hydrogel | Silicone Hydrogel (SiHy) |
|---|---|---|
| Water Content | 38% - 42% | 45% - 55% |
| Oxygen Permeability (Dk/t) | ~12 - 15 | 80 - 120+ |
| Modulus (Stiffness) | Lower (Soft & Adaptive) | Optimized (Easy Handling) |
Our ISO-certified facility features advanced quality control equipment and automated packaging systems to ensure every lens meets medical-grade parameters.
Automated precision injection molding maintains tight dimensional tolerances, preventing defects on the lens edge and surfaces.
Class ISO 8 air filtration environment blocks contamination during critical polymerization, washing, and filling stages.
Every production run undergoes strict diopter and geometrical testing to verify safety and visual clarity before shipment.
We are integrating Phosphorylcholine (PC) into the monomer composition. PC mimics the biological structure of ocular cells, reducing protein deposition and providing day-long hydration for dry-eye sufferers.
Our sandwich-molding color lock process prints patterns between polymer layers rather than directly on the lens surface. This prevents any chemical dye from interacting directly with the corneal epithelial cells.
We are reducing monomer waste by introducing bio-based polymers and closed-loop molding lines. These measures help control production costs while supporting ecological standards for eco-conscious markets.
Our global solutions are designed to simplify market entry for international contact lens brands. We handle the manufacturing complexities—including raw material sourcing, optical parameter calibration, customized visual packaging, and regulatory documentation—allowing you to focus on marketing and brand growth.
By integrating smart manufacturing processes, our facilities optimize both production output and raw material yields. The transition to automated casting molding systems has reduced structural micro-defects by 99.4%, resulting in consistent comfort and visual clarity across production lots.
Our cleanroom workflow covers the entire manufacturing process, from monomer preparation to sterilization and lot storage.
We perform optical power, hydration, and thickness verification on every production batch using calibrated instrumentation.
Operating in the medical device industry requires strict regulatory adherence. Guangzhou Chroma Lenses Technology maintains comprehensive compliance validation protocols to streamline the import process for global markets.
Compliance Standard: All products are manufactured in facilities certified to ISO 13485:2016 and hold CE certification under the European Medical Devices Regulation (MDR 2017/745). This guarantees safety, performance, and design consistency across shipments.
We supply dynamic packaging options to meet branding and shipping specifications:
We partner with international freight forwarders to provide air and sea shipping solutions, customs documentation, and localized regulatory compliance support for destination ports in Europe, North America, and Southeast Asia.
Key information regarding production compliance, custom orders, order minimums, and shipping timelines.
Complete product portfolio featuring advanced cosmetic designs, specialty patterns, and customizable retail packaging boxes.
