R&D & Material Science Technological Innovations Driving Daily Colored Contact Lens Evolution
The engineering frontier of daily colored contact lenses is rooted in advanced macromolecular chemistry and sub-micron surface manufacturing. At Mylensora Technology Co.,Ltd, our in-house engineering team continuously pushes the limits of material biocompatibility, visual optics, and wearing comfort.
1. Silicone Hydrogel Matrix Integration: Historic colored lenses relied primarily on standard HEMA polymers with low oxygen transmissibility (Dk/t around 10 to 18), limiting comfortable wear to 4-6 hours. Mylensora's next-generation silicone hydrogel daily color lenses increase oxygen transmissibility significantly (Dk/t exceeding 80+), delivering pure corneal oxygenation that prevents neovascularization and eye redness even during extended wearing cycles.
2. Multi-Layer Sandwich Encapsulation: Using precision computerized micromolding, our pigments are locked hermetically between two ultra-smooth polymer layers. This eliminates the frictional abrasion caused by exposed surface color particles against the palpebral conjunctiva, while maintaining optical clarity through high-precision refractive matching.
3. Advanced Hydrophilic Surface Treatments: By incorporating internal wetting agents such as PVP (polyvinylpyrrolidone) and utilizing plasma surface activation, our daily disposable lenses maintain low contact angles below 25°. This resists lipid and protein deposit formation and preserves tear film stability during screen time and dry air-conditioned environments.
4. High-Definition Multi-Matrix Aspheric Optics: Unlike standard spherical colored lenses that degrade in low-light environments when the human pupil expands, Mylensora designs incorporate aspheric surface correction. This controls spherical aberration, offering crisp, high-definition visual acuity while keeping the cosmetic color zone completely outside the pupil visual axis.
