Constar launches silicone hydrogel colored lens technology

Gansu Constar Technology Group has launched a patented silicone hydrogel platform for colored contact lenses, aiming to pair high oxygen permeability with cosmetic color effects. The move could speed adoption of healthier premium colored lenses across regulated markets worldwide.

Why it matters: - Silicone hydrogel is widely viewed as a safer, more comfortable material for longer wear because it transmits more oxygen to the cornea. - Colored lenses have historically faced a tradeoff between appearance and eye health when pigments interfere with oxygen flow. - Constar's launch could push the premium colored-lens market toward higher-comfort, higher-compliance materials.

What happened: - Gansu Constar Technology Group announced the launch of its patented silicone hydrogel technology for colored contact lenses on Aug. 7, 2026, in Baiyin, Gansu, China. - The product is branded Patented Sandwich Comfort Technology. - Constar is one of China's largest contact lens manufacturers. - The company is offering the technology to OEM and ODM partners.

The details: - The technology uses a dual-layer encapsulation process. - Color pigments are sealed between two micro-layers of silicone hydrogel polymer. - The structure keeps dyes away from both the cornea and the eyelid. - Constar says the design preserves oxygen transmission while delivering color. - The company says the lenses can reduce dryness, extend comfortable wear time and lower the risk of hypoxia-related complications. - Silicone hydrogel is described as offering up to five times greater oxygen transmissibility than traditional hydrogel materials. - The colored lens line covers natural enhancement tints, seasonal fashion colors, sparkle gradients and specialty cosplay designs. - Product specifications and samples are available through the company's official channels. - Qualified physical samples can be delivered in about 10 days. - Full production runs take 30 to 45 days. - The company operates under FDA, CE 0197 and ISO 13485 certifications. - Constar also lists regional certifications including AKL for Indonesia, TGA for Australia and SFDA for Saudi Arabia. - The company says it is the only contact lens manufacturer in China to hold FDA, CE 0197 and ISO 13485 simultaneously. - Constar has six production facilities and combined capacity of more than 15 million lenses per month. - The company serves partners in more than 50 countries. - Constar was founded more than 40 years ago and is headquartered in Baiyin, Gansu Province. - More information is available on the company's official website.

Between the lines: - The launch targets a growing consumer preference for lens materials that prioritize eye health as well as appearance. - Constar is positioning itself as a cost-competitive supplier for global brands that need compliance documentation for multiple markets. - The company is using scale and certifications as a competitive advantage against established silicone hydrogel colored-lens makers in Japan and South Korea. - Constar's leadership expects silicone hydrogel colored lenses to become the premium standard within two to three years.

What's next: - Brand owners and distributors can request complimentary samples and technical specifications for evaluation. - Constar will likely use the new platform to expand OEM and ODM supply into more regulated markets. - Wider adoption could follow if the technology proves scalable across color and fashion lens categories.

The bottom line: - Constar is betting that colored lenses can be both more stylish and more oxygen-permeable, and it wants to make that combination the new premium default.
