Biocompatibility & Engineering Micro-Encapsulation "Sandwich" Technology
How Vibebeautylens Technology Co., Ltd. guarantees ocular health through advanced polymer chemistry.
The primary concern for health authorities (such as the US FDA and European Medicines Agency under CE MDR) regarding cosmetic contact lenses is pigment leaching. Substandard private label manufacturers often print colors directly onto the lens surface, exposing the delicate corneal epithelium to toxic colorants and structural friction.
At Vibebeautylens Technology Co., Ltd., our manufacturing protocol utilizes a triple-layer Sandwich Color Encapsulation System. Organic, non-toxic bio-pigments are locked between dual transparent layers of hydrogel/silicone-hydrogel material. This prevents direct contact between color inks and ocular tissue, ensuring 0% pigment migration while preserving a smooth, wettable surface for all-day wearing comfort.
